Novibra type RA
FEATURES
RA uses the rubber profile in shear and compression, obtaining good vertical flexibility with the advantage of horizontal stability. For normal speeds of approx. 1500 rpm, the
RA type provides a degree of isolation of 75-85%. For even
better isolation, the alternative RAEM or M can be chosen.
Its unique construction and the latest production methods make Novibra type RA a high performance mounting having a number of advantages:
APPLICATION
For the effective isolation of vibration and noise on
different machines with rotating movements, like:
•
•
•
•
compressors
combustion engines
generators
converters
• pumps
• industrial and
marine gen-sets
• fans
Also suitable for use with presses, punches and other
workshop machines.
• Rubber features are utilised effectively combining
compression and shear.
• Tight tolerances on dynamic stiffness rate for accurate
vibration calculations.
• Wide load rating options, 40-2100 kg.
• Corrosion protected to cope with arduous environments
on land or marine applications (Fe/Zn 8C as per
ISO 2081).
• Stronger base metal withstands high shock loads
without deformation.
• Fitted as standard with a shock-proof device with resilient stop, making RA ideal for use on mobile or marine
applications. The RA-mounts can manage occasional
shock loads up to 5 g refered to the weight in hardness B.
The mount can withstand shock loads up to 2 g
without plastic deformation.
• Clear and durable product marking so that mountings
can be identified even after several years in operation.
• Domed shape cover to protect against oil contamination.

FEATURES
Novibra type BA utilises bonded rubber in shear to permit relatively high deflections to occur, thus providing
excellent isolation of low frequencies. (Type BA 20/2 is a
halfsection suitable for very light loads).
On revolving equipment applications the soft axis should
be at right angles to the shaft, whilst in mobile applications the stiff axis should be aligned in the direction of
travel.
For transit case applications the mountings need to be
arranged so that the horizontal stiffness is the same in all
directions.
APPLICATION
Novibra type BA is equally suitable for isolating vibrations from low speed machines and equipment whilst also
protecting sensitive and lightweight units from external
shocks and vibrations.

Type BA is very easy to install and ideal for applications
like:
• light fans and compressors
• portable gensets and pumps
• computers and electronic units
• transit cases
• measuring and test instruments
• gauging equipment

Novibra type HK/MK
APPLICATION
Novibra type HK/MK has a special resilient nature and
impact resistance which make it suitable for isolating
combustion engines in mobile applications as in ships,
heavy construction vehicles and tractors. HK is also suitable for isolation of cabs on the same type of machines.
The MK is supplied with shock absorbing washers, whilst
washers for the HK 150 and HK 600 should be ordered
separately.
FEATURES
Novibra Antivibration mounting type HK/MK is designed to permit high compression under vertical load but is
at the same time stable in the horizontal direction.
The conical shape makes the rubber work in both shear
and compression stresses in a favourable way.

Novibra type UH
FEATURES
Novibra UH is an anti-vibration mounting designed to
accommodate axial static and shock loads in both directions. The dynamic natural frequency is constant irrespective of the static load.
When fitted with overload/rebound washers, a high
strenght fail-safe installation is provided. Moreover, it is
possible to alter the characteristics of the mounting by
providing an extra dome-shaped washer on the top rubber-section, which will provide impact resistance against
deflection beyond the permissable limit.
Installation of the mounting can be done in an easy way
and reduces necessary build tolerances.
APPLICATION
Novibra mounting type UH is particularly suitable for
the suspension of both mobile and static cabins as well as
platforms on agricultural vehicles.
Whilst vibration and noise is effectively isolated the UHmounting also protects tanks and ancillary equipment
against metal fatigue caused by chassis distortion.
Specific applications can be found on :
• tractors
• combine harvester
• wheel-mounted loaders
• street sweepers
• compactors
• lifting cranes
• construction vehicles
• forestry vehicles
• off-the-road equipment
• fork-lift trucks
• excavators
UH is available in 2 standard versions allowing different
maximum loads i.e. type UH 50 for up to a load of 250 kg
and type UH 70 up to 400 kg per mounting.
Note: Maximum tightening torque of bolts:
• UH 50 80 Nm
• UH 70 120 Nm

Novibra type SAW
FEATURES
Novibra type SAW mountings consists of a cylindrical
shaped rubber section with integrally bonded interleaf
metal plates which is bonded to two square heavy duty
outer metal fixing plates. It has been designed for large
compressive thrust forces with minimum deformation,
whilst providing low shear stiffness rates.
The combination of a stable low installation height, high
compressive strength and low shear stiffness makes
Novibra type SAW a versatile high performance antivibration mounting. Installation is easy due to only 4 clearance
holes in each fixing plate.
APPLICATION
Novibra elements type SAW are heavy duty mountings
for high vertical static and shock loads in compression,
whilst at the same time providing high isolation values in
the horizontal shear direction.
By connecting 2 SAW-elements in series i.e. one on top of
another, an increased isolation efficiency is achieved in
both shear and compression planes to isolate very low frequencies. Where large deflections are required in the vertical plane Novibra type SAW mountings can be mounted
at a calculated angle configuration to provide the optimum spring rate between shear and compression stiffness.
Typical fields of application are:
• crushers
• edge runners
• mills
• grinders
• hoppers and feeders
• vibratory rollers
• screens
• other very heavy
machines and
equipment

Novibra Anti-vibration Plate
Suitable applications are:
• pillar drills
• transformers
• large pumps
• printing presses
• industrial fans
• horizontal drill presses
• textile machinery
• large forging presses
FEATURES
The Novibra Anti-vibration Plate, made of oil and grease
resistant rubber material, is available either as a single (4.5
mm) or as a double (8 mm) version. The single version
has ribs on one side only, while the double has ribs on
both sides applied in a 90 degree angle to each other.
APPLICATION
The Novibra Anti-Vibration Plate is intended, primarily,
for applications with low demands on vibration isolation.
Typical installations would be machinery generating
vibrations in the high frequency range, and also for tall
unstable installations, which require secure attachments
to the foundation.
Good performance is also obtained when using the
Novibra plate in the building and construction industry
as support pads between flooring and joists. This application provides for cushioning of loads and isolation of
high frequency vibrations within the building.
If insufficient deflection is achieved by a single layer, multiple layers can be used by separating each layer with a
steel plate for the purpose of weight distribution.
In order to avoid direct contact between machine and
foundation, a rubber bushing (e.g. rubber hose) should
be installed in the mounting holes prior to installation of
bolt and rubber washer. See ”Mountings instructions” on
this page.

Novibra type TF
FEATURES
The TF mounting can be installed in a matter of minutes
by following the instructions provided. There is no need
to fix the machines to the floor since the rubber sole of

Novibra type U
FEATURES
Novibra type U is a robust element consisting of 2 solid
U-shaped steel parts securely bonded with rubber. To
achieve higher resilience two holes in the rubber have
been provided under the innershanks. The upper steel
plate is to be mounted under the machine foot or baseplate by means of a bolt whereas the bottom plate should
be secured to the floor by e.g. an expansion bolt.
For certain applications a dowel pin may be adequate.
APPLICATION
Type U provides for a stable machine installation and is
therefore particulary suitable for the vibration isolation of
heavier machinery with relatively high interfering frequencies.
Typical applications can be found on :
• presses
• punches
• weaving machines
• carpentry machines
• church bells
• transformers
• printing machinery
• other heavy high speed

Novibra type SE
FEATURES
The SE-mounting consists of an annular rubber section,
securely bonded to a single steel support plate. A clearance hole is provided which can either be left plain or tapped to suit the application.
Since the rubber component is in direct contact with the
surface, friction is sufficient to prevent the equipment
from ”travelling”.
APPLICATION
Novibra type SE is most suitable for the isolation of high
frequency disturbances and also provides reduction of
structure borne noise.
Specific applications are:
• office equipment
• textile machinery
• domestic appliances
• electric motors
• weighing equipment

Novibra shockbuffer type ANB
FEATURES
Novibra buffer type ANB consists of a cylindrical rubber
body bonded to a square baseplate of steel. Each corner of
the baseplate has a fixing hole.
Special high-hysteresis rubber compound is used to ensure as much energy absorption as possible so that the volume of the rubber is used at an optimum efficiency.
It permits that for new machine developments simpler
designs and lighter calculated forces can be considered
which means lower costs.
APPLICATIONS
The Novibra shockbuffer type ANB is used to effectively
damp movements of machines or machine components
which need to be slowed down or stopped.
Fig 1. Traverse crane with shock buffer ANB.
Typical field applications would be:
• wagons
• cabinets
• traverse cranes
• forestry vehicles
• lifting cranes
• off-road material
handling equipment
• working beams
• falling goods
Through the excellent resilience of the rubber a high
degree of energy absorption can be achieved. The rubber
is stiffer for rapid dynamic processes than for slow static
applications. With the same deformation this means that
more energy is absorbed in fast processes than in slow
ones. Diagram 1 shows the impact of the energy factor.

CALCULATION EXAMPLES

EXAMPLE 1: FREE FALL CALCULATION
1850 kg weight is to be dropped 1.83 metres onto 4 ANB
buffers. What size ANB should be used? What force will be
transmitted to the floor?
Energy E = F · S (2) = 1.83 · 1850 · 9.81 = 33212 NM
Velocity at impact (shock velocity) V =
2 · g · h (7)= 2 · 9.81 · 1.83 = 6 m/s.

REFER TO ENERGY FACTOR GRAPH
If 50% deformation is allowed, the energy factor at 6 m/s
is 0.4.
Then dynamic energy 33212 Nm corresponds to 33212 ·
0.4 = 13285 Nm static energy and for 4 buffers the static
energy per buffer is 3320 Nm.
REFER TO FORCE-ENERGY DIAGRAM
Select ANB 200 which can each absorb up to 4300 Nm
at 80 mm compression (which is 50% of static height) or
will compress 76 mm at 3320 Nm.
Force at impact surface
= force at 76 mm deflection / 0.4
= 150 / 0.4 =375 kN per buffer
= 1500 kN for 4 buffers
Hence if 1850 kg is dropped 1.83 metres onto 4 x ANB 200
buffers they will each compress 76 mm and the total force on
the floor will be 1500 kN.
EXAMPLE 2A: CRANE BUFFER CALCULATION
A crane weighs 2000 kg and travels at 1.6 m/s. What size ANB
buffers should be used to stop it and what will the final force be?
The dynamic or kinetic energy E =
1 = m · v2 = 2000 · 1.62 = 2560 Nm (1)
2
2
REFER TO ENERGY FACTOR GRAPH
Assuming a 50% deformation, the energy factor = 0.75 at
1.6 m/s.
Hence the equivalent static energy is 2560 · 0.75 = 1920 Nm.
Then for 2 buffers the static energy is 960 Nm per buffer.
REFER TO FORCE-ENERGY DIAGRAM
ANB 150 buffers can be chosen with a deflection at 960
Nm of 49 mm, which is only 41% of a free height of 120
mm, whereas 50% had been assumed. With the energy
factor reduced to 0.72 (for 41% deflection at 1.6 m/s) the
static energy is:
15 %

Energy factor
Hence 2 x ANB 150 buffers will deflect 48.5 mm and transmit a
force of 71 kN or 7240 kg each, i.e. the structure must withstand
14.6 tons.
EXAMPLE 2B: CRANE BUFFER CALCULATION
How can the dynamic force calculated in example 2a be
reduced, and by how much?
The force will be reduced and the deflection will be increased if ANB 150 buffers are connected in series (i.e. 4
buffers instead of 2) as illustrated by fig. 2.
Then, assuming 30% deformation the energy factor at
1.6 m/s = 0.68.
Hence the equivalent static energy is 2560 · 0.68 = 1740 Nm
and for 4 buffers the static energy is 435 Nm per buffer.
The force-Energy diagram shows that at 435 Nm, buffer
ANB 150 deforms 35 mm. This corresponds to 29.2% of
a free height of 120 mm which is close to assumed value
30%.
Then the static force at 35 mm deformation is 26 kN and
the dynamic load at impact will be:
26 / 0.68 = 38 kN
Hence 4 x ANB 150 buffers connected 2 + 2 will give a total
deflection of 70 mm with a final force per double arrangement of
38 kN or 3870 kg, i.e. the structure must withstand 7.7 tons.
2560/2 x 0.72 = 922 Nm
REFER TO FORCE-ENERGY DIAGRAM FOR ANB 150
At 922 Nm static energy, the deflection is 48.5 mm (close
to 49 mm).
Then the static force at 48.5 mm deflection is about 51 kN.
Therefore the dynamic load (Force at impact) =
51 / 0.72 = 71 kN.

Novibra type HA
FEATURES
Novibra type HA is a height adjuster made in corrosion
protected steel. The steel is zink plated and chromated
according to DIN 50691/ISO 2081.
The height adjuster is supplied complete with washer and
nut for the fastening to the mounting and two nuts and a
lock washer for the engine foot fastening.
The HA height adjustment facilities precise coupling
alignment for engine installations and boat building
tolerances.
APPLICATION
Novibra type HA is available in 4 versions to suit the
small and medium range of Novibra AV-mountings, as
listed on table below. It also allows Novibra mountings to
be retrofitted to existing installations where original spares are unobtainable.
Notes :
• For optimum solutions where close coupling tolerances
are required, leave the mountings to settle for 24 hours
before final alignment of the engine installation.
E
C
• For securing the bolt into the mounting, it is
C
recommended to apply Loctite.
1
• For the dimensions HA 16/16 and 16/20 it is necessary
to use a larger washer than nr 4 in the sketsch, approx
30% of the diameter of the upper part of the cover.
3
A
1
• For mobile applications it is recomended to use a
washer (see part 4 in table below) that has the same
size as the diameter of the upper part of the cover for
the corresponding RA, RAB and RAEM mount.
