Welcome to HIWIN
A linear guideway permits linear movement with the aid
of rolling elements. By using balls or rollers between the
rail and block, a linear guideway can attain an extremely
precise linear movement. Compared with a standard
sliding guide, the friction coefficient here is just one
fiftieth. The good efficiency and zero play mean that the
linear guideway can be used in various ways.

1. General information
1.1 Properties and advantages
1.1.1 Properties and advantages of linear guideways
1. High positioning accuracy
A carriage mounted with a linear guideway only has to overcome rolling friction. The
difference between the static and dynamic rolling friction is very small so the breakaway force is only slightly greater than the motion force. Stick-slip effects are not
experienced.
2. Long lifetime and highly precise movement
With a sliding guide, the different thicknesses of lubrication film may result in accuracy errors. The sliding friction and the fact that lubrication is often insufficient cause
a lot of wear and therefore decreasing accuracy. Contrasted with this, the linear guideway has very low rolling friction, coupled with extremely low wear. Guidance accuracy
remains virtually constant over the entire lifetime.
3. High speed and low driving force
The low friction coefficients mean that only low driving forces are needed. The required
power also remains low when reversing.
4. Same high load capacity in all directions
Thanks to the enforced guidance inherent in its design, a linear guideway can absorb
forces in a vertical and horizontal direction.
5. Simple installation and interchangeability
Assembling a linear guideway is a simple process. A high level of accuracy is achieved
with a milled or ground mounting surface if the assembly instructions are followed.
Standard sliding guides require considerably more effort to assemble as the sliding
surfaces have to be scraped. Individual components cannot be interchanged without
scraping. Linear guideways can however be interchanged with very little effort.
6. Simple lubrication
Insufficient lubrication on sliding guides destroys the sliding surfaces. Lubricant must
be used at a large number of points on the sliding surfaces. The linear guideway only
requires minimal lubrication which is provided by a simple supply line to the block.
HIWIN can also supply blocks with an integrated oil lubrication unit and interchangeable oil tank for long-term lubrication.
7. Corrosion protection
To achieve optimum corrosion protection, blocks and rails can be supplied with different coatings. The individual procedures selected depend on the application. Data relating to the ambient conditions and corrosive substances is needed for an optimum
choice of coating. The miniature linear guideways MG and PM are produced in stainless
steel.

General information
Load ratings
1.3 Load ratings
1.3.1 Static load rating C0
If a linear guideway is subject to disproportionately high loads or impact during movement or when stationary, local permanent deformation occurs between the block and
balls. Once this permanent deformation exceeds a particular level, it impacts on how
easily the guide moves. By definition, the static load rating corresponds to a static load
which causes a permanent deformation of 0.0001 × ball diameter at the point of
contact subject to the most loading. The values are stated in the tables for each linear
guideway. These tables can be used to select a suitable linear guideway. The maximum
static load to which a linear guideway is subjected must not exceed the static load
rating.
1.3.2 Permissible static moment M0
The permissible static moment is the moment that corresponds to the greatest
possible loading of moving parts by the static load rating in a defined direction and
magnitude. The permissible static moment is defined in three directions (MX, MY and
MZ) for linear movement systems.
MX
MY
1.3.3 Static structural safety
Static structural safety, which depends on the ambient and operating conditions, must
be taken into account for rail systems at rest or moving slowly. A higher level of structural safety is especially important for guides subject to impact loads, see Table 1.1.
The static structural safety can be calculated using Formula 1.1.

1.3.4 Dynamic load rating Cdyn
The dynamic load rating is the defined loading (in direction and magnitude) at which a
linear guideway achieves a nominal lifetime of 50 km 1) travel distance (HG, QH, EG, QE,
WE, MG, TM) or 100 km 1) (RG). The dynamic load rating is stated for each guide in the
dimension charts. This can be used to calculate the lifetime of one particular guide.
1) Note
The dynamic load rating of linear guideways is stated for a lifetime of 50 or 100 km
travel distance depending on the manufacturer. The following factors can be used to
convert the dynamic load rating.
Cdyn 50 km = 1.26 × Cdyn 100 km (series HG, QH, EG, QE, WE, MG, TM)
Cdyn 50 km = 1.23 × Cdyn 100 km (series RG)

1.4 Lifetime calculation
1.4.1 Definition of lifetime
Continual and repeat loading of the tracks and balls on a linear guideway causes signs
of fatigue on the track surface. Ultimately this results in what is known as pitting.
1.4.2 Nominal lifetime (L)
The lifetime may vary significantly even if the linear guideways are produced in the
same way and used under the same movement conditions. The nominal lifetime should
therefore be viewed as a rough estimate of the lifetime of a linear guideway.
The lifetime of a linear guideway is defined as the total travel distance covered until
pitting starts to form on the surface of the track or balls.
The nominal lifetime corresponds to the total travel distance which 90 % of a group of
identical linear guideways reach under the same conditions without failure.
1.4.2.1 Nominal lifetime calculation
The actual loading affects the nominal lifetime of a linear guideway. The nominal
lifetime can be calculated with Formulas 1.2.1 and 1.2.2 using the selected dynamic
load rating and equivalent dynamic loading.

L = Nominal lifetime [km]
Cdyn = Dynamic load rating [N]
P = Equivalent dynamic loading [N]
1.4.2.2 Factors affecting nominal lifetime
The type of loading, hardness of the track and temperature of the guide have a
considerable impact on the nominal lifetime. Formulas 1.3.1 and 1.3.2 show the
relationship between these factors.
Hardness factor (fh)
The tracks of the linear guideways have a hardness of 58 HRC. A hardness factor of
1.0 applies. If the hardness differs from this, the hardness factor shown on the right
should be used. If the stated hardness is not reached, the permissible loading is
reduced. If this happens, the dynamic and static load ratings must be multiplied by the
hardness factor.
Temperature factor (ft)
Standard rails can be used in an ambient temperature range of –10 to 80 °C. At
ambient temperatures up to 150 °C, linear guideways with a metallic end cap must be
used (identified in the type code by the addition “/SE”). Intermittent ambient temperatures of up to 180 °C are possible. However, we do recommend contacting our technical support team to be sure. If the temperature of a linear guideway exceeds 100 °C,
the permissible load and lifetime are reduced. The dynamic and static load ratings
must therefore be multiplied by the temperature factor.

General information
Lifetime calculation
Load factor (fw)
The loads affecting a linear guideway include the weight of the block, the inertia at the
start and end of movements and load torques which are caused by the projection of the
load. These load factors are particularly hard to estimate when accompanied by vibration or impact load. The load should therefore be multiplied by the empirical load factor. The load factor calculated should be doubled for short-stroke applications (stroke
= 2 × block length).

1.5 Operating load
1.5.1 Operating load
When calculating the loads acting on a linear guideway, various factors must be taken
into account, e.g. the focal point of the load, the motion force's point of entry and the
mass inertia at the start and end of movement. To obtain a correct value, each parameter must be taken into account.

1.5.2 Calculation of equivalent load during changing loads
If loading of a linear guideway fluctuates greatly, an equivalent load must be used in
the lifetime calculation. The equivalent load is defined as the load which causes the
same wear on the bearings as the changing loads. It can be calculated using Table 1.9.

1.6 Friction and lubrication
1.6.1 Frictional resistance
Using rolling elements in the linear guideway mainly reduces friction on the roll
friction of the rolling elements. This makes the friction coefficient of linear guideways
very low, up to one fiftieth of that of traditional sliding guides. Generally, the friction
coefficient is around 0.004 depending on the series. If the loading is only 10 % or less
of the dynamic load rating, most of the frictional resistance is caused by the wiper and
grease and friction between the rolling elements. If the operating load is more than
10 % of the dynamic load rating, the load provides the majority of the frictional
resistance.
1.6.2 Lubrication
Like any other roller bearing, linear guideways need a sufficient supply of lubricant. In
principle, both oil and grease can be used for lubrication. The lubricant is a design
element and should be taken into account when designing a machine.
Formula 1.5
F: Frictional force [N]
S: Frictional resistance [N]
µ: Friction coefficient
W: Load [N]
Lubricants reduce wear, protect against contamination, reduce corrosion and their
properties extend the service life. Dirt may build up on unprotected rails. This dirt must
be removed on a regular basis.
You will find information about the HIWIN lubricants in the accessories chapter on page
120. You will also find details about the HIWIN lubricants and lubrication of the linear
guideways in the “HIWIN assembly instructions for linear guideways” available
from www.hiwin.de.
HIWIN provides greases for various requirements:
○ HIWIN G01 heavy-duty applications
○ HIWIN G02 clean room and vacuum applications
○ HIWIN G03 high-speed clean room and vacuum applications
○ HIWIN G04 high-speed applications
○ HIWIN G05 standard applications
1.6.3 Oil lubrication unit E2
The oil lubrication unit E2 consists of a lubricating unit between the deflection system
and the end seal, and an interchangeable oil tank. The block does not need to be
disassembled in order to interchange the oil tank. Lubrication passes from the oil tank
via the connector to the lubricating unit which then lubricates the track of the rail. Due
to the specific design of the oil tank, the block can be assembled in any position with-
out influencing the lubrication effect. The oil lubrication unit E2 can be used at an
ambient temperature of –10 °C to +60 °C. The replacement intervals depend greatly
on the loads and the environmental conditions. Environmental influences such as high
loads, vibrations and dirt shorten the replacement intervals.
The oil lubrication unit E2 is available for the HG, EG and RG series. You will find the
corresponding dimensions, lubricant volumes and intervals in the chapters for the
corresponding series. Series HG page 39, series EG page 56, series RG page 105.

General information
Mounting position
1.7 Mounting position
1.7.1 Examples of typical mounting positions
A linear guideway can absorb loads from above/below and right/left. The mounting
position depends on the requirements of the machine and the loading direction. The
precision of the rail is defined by the straightness and evenness of the installation
surfaces, since the rail is attached to these while the screws are being tightened.
Profile rails that are not attached to an installation surface may have larger tolerances
in terms of straightness. Below you will find typical mounting situations: Details of the
assembly tolerances can be found in the chapters for the individual series.
A profile bar on a reference edge:
The reference edge is identified by arrows on the top of the rail. For very short rails,
identification is on the front side of the rail.

1.8 Assembly
1.8.1 Types of assembly
Depending on the accuracy required and the linear guideway’s impact and vibration
loading, the following three types of assembly are recommended.
1.8.1.1 Assembly of rails with reference edge and clamp
If the machine is subject to severe vibration, impact or lateral force, guides and blocks
may move. To avoid this problem and achieve a high level of rigidity and guidance
accuracy, we would recommend assembling the linear guideway with reference edges
and clamps on both sides.

1.8.4 Joint rails
Joint (multi-part) rails must be assembled according to the markings on them. The
joints of each section are identified in consecutive alphabetical order as well as by the
rail/pair number so that each rail section can be clearly assigned.
Each joint is printed on the top of the rail. This assists with initial assembly and can be
removed at any time using a suitable cleaning agent (e.g. methylated spirit). For paired
multi-part rails, the word “Paar” must also be stated in addition to the rail number.

General information
Sealing systems
1.9 Sealing systems
1.9.1 Sealing systems SS, ZZ, DD, KK
The HIWIN end seals firstly prevent the ingress of foreign substances such as dust particles, chips or liquid into the block's ball tracks and secondly reduce the amount of
lubricant lost. HIWIN provides various sealing systems for the various ambient condi-
tions of your application. The effectiveness of the end seal impacts directly on the
lifetime of the linear guideway and should therefore be taken into account at the
design stage and selected to suit the ambient conditions of your application.
SS (standard):
End seal with bottom seal
○ For applications with little dirt and dust
○ Only minimal increase in displacement forces
ZZ:
End seal with bottom seal and scraper
○ For applications associated with hot chips or sharp-edged particles of dirt
○ The scraper protects the end seal and prevents it from being damaged
DD:
Double end seal with bottom seal
○ For applications associated with a lot of dirt and dust
○ The double end seal effectively prevents the ingress of dirt into the block
KK:
Double end seal with bottom seal and scraper
○ For applications associated with a lot of dirt and dust and hot chips or sharp-edged
particles of dirt
○ The scraper protects the end seals and prevents them from being damaged
Availability of sealing systems SS, ZZ, DD and KK:
Sealing systems SS, ZZ, DD and KK are available for all series and sizes.
The exceptions are the MG and PM series, for which only the standard sealing system SS is available.

1.9.2 Sealing systems SW and ZWX for optimum dust protection
Sealing systems SW and ZWX allow HIWIN linear guideways to also be used in areas
with very high levels of dirt. The sealing systems offer optimum protection against
the ingress of dirt, dust and liquid. The end seal is resistant to oils and greases and
very resistant to wear.
Properties:
○ End seal with double sealing lip
○ Optimized bottom seal
○ Additional top seal
○ Optimized stainless steel scraper
Advantages:
○ Optimum dust protection
○ Lifetime extended ten-fold
○ Longer lubrication intervals
○ Lower maintenance costs
SW:
End seal with double sealing lip, optimized bottom seal and additional top seal
○ The additional top seal prevents the ingress of dirt via the top of the rail
○ The optimized bottom seal protects against the ingress of dirt on the rail flank
ZWX:
End seal with double sealing lip, optimized bottom seal, additional top seal and
optimized scraper
○ The additional top seal prevents the ingress of dirt via the top of the rail
○ The optimized bottom seal protects against the ingress of dirt on the rail flank
○ The optimized scraper also protects against dirt particles > 0.2 mm in diameter and
prevents damage to the end seal.
Dust test for sealing systems SW and ZWX
Thorough dust tests have shown that the lifetime with sealing
systems SW and ZWX is ten times longer than that with a
standard seal in cases of high dust levels.
Test conditions:
○ Sealed room in which MDF dust is swirled about
○ v = 1.3 m/s
○ Grease lubrication

General information
SynchMotion™ technology
1.10 SynchMotion™ technology
1.10.1 SynchMotion™ technology
The innovative SynchMotion™ technology reduces contact between the rolling elements and with the block. Like the ball cage of a standard ball bearing, the rolling
elements are kept a defined distance from one another using SynchMotion™ technology. Reciprocal friction, as is produced in standard linear guideways, is therefore
prevented and synchronous fluctuations are greatly reduced. No uncontrolled ball
movements occur, even at high speeds. SynchMotion™ technology also improves the
transport of lubricant within the block and the storage of lubricant.
Advantages:
○ Improved synchronous performance
○ Optimised for high travel speeds
○ Improved lubrication properties
○ Less running noise

2.2 Linear guideway, series HG and QH
2.2.1 Properties of the linear guideways, series HG and QH
The HIWIN linear guideways of the HG series with four ball tracks are designed for high
loads and rigidities. Due to the 45° arrangement of the ball tracks the HG series can
equally take loads from all directions. Low displacement forces and a high efficiency
are further features of the HG series. The ball retainers prevent the balls from falling
out when the block is pulled off the rail during assembly.
The models of the QH series with SynchMotion™ technology offer all the advantages of
the standard series HG. Controlled movement of the balls at a defined distance also
results in improved synchronous performance, higher reliable travel speeds, extended
lubrication intervals and less running noise. Since the installation dimensions of the
QH blocks are identical to those of the HG blocks, they are also fitted on the HGR
standard rail and can therefore be interchanged with ease. For more information, refer
to page 22.
2.2.2 Structure of the HG/QH series
○ 4-row recirculation ball bearing guide
○ 45° contact angle of ball tracks
○ Ball retainers prevent the balls from falling out when the block is removed
○ Various sealing variants depending on the field of application
○ 6 options for connecting grease nipple or lubrication adapter
○ SynchMotion™ technology (QH series)

2.2.3 Advantages
○ Zero play
○ Interchangeable
○ High accuracy
○ High loading capacity in all loading directions
○ Low friction losses even with preload thanks to optimized
ball tracks and 2-point contact
Additional advantages of QH series
○ Optimized for higher travel speeds
○ Extended lubrication intervals
2.2.4 Article numbers of the HG/QH series
For HG/QH linear guideways, a distinction is made between interchangeable and noninterchangeable models. The dimensions of both models are the same. The main difference is that the block and rail in the interchangeable models can be freely interchanged. Block and rail can be ordered separately and fitted by the customer. Their
accuracy extends to class P.
Given their stringent dimensional accuracy check, the interchangeable models are a
good choice for customers who do not use rails in pairs on one axis. Non-interchangeable linear guideways are always supplied preassembled. The article numbers of the
series include the dimensions, model, accuracy class, preload etc.

2.2.7.1 Definition
Every rail type can be preloaded. Oversized balls are used for this purpose. Normally a
linear guideway has negative clearance between track and balls to increase rigidity and
precision. The curve shows that the rigidity doubles at higher preload. For rails below
the nominal size of 20, a preload of no more than ZA is recommended to avoid the lifetime being shortened as a result of preload.

Note
1. The tolerance for E is +0.5 to –1 mm for standard rails and 0 to –0.3 mm for joints.
2. If the E1/2 dimensions are not indicated, the maximum possible number of mounting holes will be determined under consideration of E1/2 min.
3. The rails are shortened to the required length. If the E1/2 dimensions are not indicated, these will be carried out symmetrically.

2.2.11.3 Calculating the length of rails
HIWIN offers rails in customized lengths. To prevent the risk of the end of the rail
becoming unstable, the value E must not exceed half of the distance between the
mounting holes (P). At the same time, the value E1/2 should be between E1/2 min and
E1/2 max so that the mounting hole does not rupture.

Linear guideways
EG/QE series
2.3 Linear guideway, series EG and QE
2.3.1 Properties of the linear guideways, series EG and QE
The HIWIN linear guideways of the EG series with four ball tracks have a low installation height, making them ideally suited to applications with a low installation space.
Despite this, the EG series has the same properties as the HG series – good loading
capacity, low displacement forces and high efficiency. The ball retainers prevent the
balls from falling out when the block is pulled off the rail during assembly.
The models of the QE series with SynchMotion™ technology offer all the advantages of
the standard series EG. Controlled movement of the balls at a defined distance also
results in improved synchronous performance, higher reliable travel speeds, extended
lubrication intervals and less running noise. Since the installation dimensions of the
QE blocks are identical to those of the EG blocks, they are also fitted on the EGR
standard rail and can therefore be interchanged with ease. For more information, refer
to page 22.
2.3.2 Structure of the EG/QE series
○ 45° contact angle of ball tracks
○ 6 options for connecting grease nipple or lubrication adapter
○ SynchMotion™ technology (QE series)
Fig. Structure of the EG series
Fig. Structure of the QE series
2.3.3 Advantages
○ Zero play
○ Interchangeable
○ High accuracy
○ High loading capacity in all loading directions
○ Low friction losses even with preload thanks to optimized
ball tracks and 2-point contact
Additional advantages of QE series
○ Extendes lubrication intervals
2.3.4 Article numbers of the EG/QE series
For EG/QE linear guideways, a distinction is made between interchangeable and noninterchangeable models. The dimensions of both models are the same. The main difference is that the block and rail in the interchangeable models can be freely interchanged. Block and rail can be ordered separately and fitted by the customer. Their
accuracy extends to class P.
Given their stringent dimensional accuracy check, the interchangeable modules are a
good choice for customers who do not use rails in pairs on one axis. Non-interchangeable linear guideways are always supplied preassembled. The article numbers of the
series include the dimensions, model, accuracy class, preload etc.

Linear guideways
WE series
2.4 Linear guideway, series WE
2.4.1 Properties of the linear guideway, series WE
The HIWIN linear guideways of the WE series are based on proven HIWIN technology.
Their large rail width and low installation height permit a compact design and high
torque loading capacity.
2.4.2 Structure of the WE series
○ 45° contact angle
○ Low installation height
○ Wide linear guideway for high torque loading capacity
○ Large mounting surface on block
Fig. Structure of the WE series
2.4.3 Advantages
○ Compact and low-cost design thanks to high torque loading capacity
○ High efficiency thanks to low friction losses
50 % wider than standard series
2-row mounting holes
○ The block’s large mounting surface supports the transfer of higher torques
○ The 45° arrangement of ball tracks permits high loading from all directions
○ Optimized geometry and high loading capacity thanks to FEM analysis of rail and
block
60
2.4.4 Article numbers of the WE series
For WE linear guideways, a distinction is made between interchangeable and noninterchangeable models. The dimensions of both models are the same. The main
difference is that the block and rail in the interchangeable models can be freely
interchanged. Block and rail can therefore be ordered separately and fitted by the
customer.
Their accuracy extends to class P. Given their stringent dimensional accuracy check,
the interchangeable modules are a good choice for customers who do not use rails in
pairs on one axis. Non-interchangeable linear guideways are always supplied preassembled. The article numbers of the series include the dimensions, model, accuracy
class, preload etc.

2.5 Linear guideway, series MG
2.5.1 Properties of the linear guideway, series MGN
The HIWIN linear guideway of the MGN series is based on proven HIWIN technology.
The Gothic arch contact design absorbs loads in all directions and is particularly rigid
and precise. Given its compact and lightweight design, it is particularly suited to use in
small devices.

2.5.3 Properties of the linear guideway, series MGW
The HIWIN linear guideway of the MGW series is based on proven HIWIN technology.
The Gothic arch contact design absorbs loads in all directions and is particularly rigid
and precise. The MGW series has a wider rail than the MGN series so can absorb considerably higher load torques.

2.5.5 Applications of the MG series
The MGN and MGW series can be used in many sectors, e.g. in the semiconductor
industry, PCB population, medical technology, robot applications, measurement
devices, office automation and other sectors needing miniature guides.

2.5.6 Article numbers of the MG series
For MGN and MGW linear guideways, a distinction is made between interchangeable
and non-interchangeable models. The dimensions of both models are the same. The
main difference is that the block and rail in the interchangeable models can be freely
customer.
good choice for customers who do not use rails in pairs on one axis. The article numbers include the dimensions, model, accuracy class, preload etc.

2.5.12 Dust protection
The blocks of the MG series are equipped on both sides with an end seal to protect
against dirt as standard. Additional seals can be fitted underneath on the side of the
block. Bottom seals can be ordered using the “+U” identifier in the article number.
They are available as options for sizes 12 and 15. They cannot be fitted for sizes 7 and
9 due to the limited installation space H1. When fitting a bottom seal, the side
mounting surface of the rail must not exceed H1.

2.6 Linear guideway, series PM
2.6.1 Properties of the linear guideway, series PMN
The HIWIN linear guideway of the PMN series is based on the proven MGN series.
Thanks to the optimised ball return in the plastic duct, the synchronous performance
and quiet running are improved and the weight is reduced by around 20 %. The Gothic
race profile absorbs loads in all directions and is particularly rigid and precise. Given
its compact and lightweight design, it is particularly suited to use in small devices.

2.6.9 Dust protection
The blocks of the PM series are equipped on both sides with an end seal to protect
against dirt as standard. Additional seals can be fitted underneath on the side of the
block. Bottom seals can be ordered using the “+U” identifier in the article number.
They are available as options for sizes 9 and 12. They cannot be fitted for size 5 due to
the limited installation space H1. When fitting a bottom seal, the side mounting
surface of the rail must not exceed H1.

Linear guideways
RG/QR series
2.7 Linear guideway, series RG and QR
2.7.1 Properties of the linear guideways, series RG and QR
The HIWIN linear guideways of the RG series use rollers rather than balls as rolling
elements. The RG series provides extremely good rigidity and very good loading
capacity. It is designed with a 45° contact angle. Its linear contact surface greatly
reduces deformation from the loading produced and therefore ensures very good
rigidity and loading capacity in all 4 loading directions. The linear guides of the RG
series are therefore ideal for use in high-precision manufacturing.
The models of the QR series with SynchMotion™ technology offer all the positive
properties of the standard series RG. Controlled movement of the rollers at a defined
distance also results in improved synchronous performance, higher reliable travel
speeds, extended lubrication intervals and less running noise. Since the installation
dimensions of the QR blocks are identical to those of the RG blocks, they are also
fitted on the RGR standard rail and can therefore be interchanged with ease. For more
information, refer to page 22.
2.7.2 Structure of the RG/QR series
○ 4-row recirculation roller bearing guide
○ 45° contact angle
○ Ball retainers prevent the rollers from falling out when the block is removed
○ 6 options for connecting grease nipple and lubrication adapter
○ SynchMotion™ technology (QR series)
Fig. Structure of the RG series
2.7.3 Advantages
○ Zero play
○ Interchangeable
○ Very high load ratings
○ Very high rigidity
○ Low displacement forces even with high preload
2.7.4 Article numbers of the RG/QR series
For RG/QR linear guideways, a distinction is made between interchangeable and noninterchangeable models. The dimensions of both models are the same. The main difference is that the block and rail in the interchangeable models can be freely interchanged. The article numbers of the series include the dimensions, model, accuracy
class, preload etc.

2.7.7.1 Definition
Every rail type can be preloaded. Oversized rollers are used for this purpose. Normally a
linear guideway has negative clearance between track and rollers to increase rigidity
and precision. The linear guideways of the RG/QR series offer three standard preloads

Linear guideways
PG series
2.8 Linear guideway, series PG
2.8.1 Properties of the linear guideways, series PG
The HIWIN linear guideways of the PG series are a special type of the HG/QH series
with the integrated, magnetic distance measuring system MAGIC. The distance
measuring systems of the MAGIC series are optimised for measuring the distances
travelled in linear movements and particularly on linear motor axes. The measuring
system consists of a magnetic measuring gauge on a stainless steel carrier tape and a
sensing unit. The robust housing with excellent electrical shielding and real-time
signal output make the HIWIN MAGIC series the distance measuring system of choice
for demanding applications.
2.8.2 Structure of the PG series
○ HG/QH series block
○ HG series rail with additional groove for measuring scale
○ Encoder can be fitted on HG-20, HG-25, QH-20 and QH-25 size blocks
○ Assembly direction: Looking towards the reference edge of the block, the encoder
is fitted on the left as standard. The encoder cable is also on the side of the
reference edge
2.8.3 Advantages
○ Zero contact measurement with 1 Vpp or digital output
○ Digital resolution of up to 0.5 μm
○ Encoder and housing are not sensitive to dust, humidity, oil and chips
○ Encoder with metal housing and IP67 protection mode
○ Simple assembly
○ Signal output in real time
○ Special housing for EMC optimization
110
In the PG series, the stylus is fitted directly on the HG/QH series block. The magnetic
tape is integrated in an additional groove in the HGR rail. The MAGIC distance
measuring system is also available as a model not dependent on the rail. The customer
can specify where the magnetic tape and stylus are positioned. For details, please refer
to the catalogue “Electric drive technology – linear motors, torque motors, positioning
measurement systems”.
