Compact ball screws offer quiet,
high-speed performance.
Compact FA Series ball screws incorporate NSK's new ball recirculation system and offer quiet, high-speed
performance. In order to respond quickly to a wide range of needs, NSK offers two-week delivery on common
sizes. These high-performing ball screws are ready for use in a variety of industries including: semiconductor
manufacturing, medical equipment and devices, factory automation and general industrial use.

Features
As much as
%
more compact
Quick delivery on common sizes
Domestic manufacturing and comprehensive stocking program ensure two-week
delivery and reduced shipping costs.
6 dB less noise
The noise level of ball screws has been reduced by 6 dB, about half of what is sensed
by the ear. Ball screws subsequently produce a quieter and gentler sound.
10%–30% more compact ball nut
The outside diameter of the ball nut is as much as 30% smaller than those of NSK
conventional products. This contributes to a more compact design of all sorts of
equipment and devices such as thinner XY tables.
-1
High-speed operation of up to 5000 min
The new ball screws offer 1.6 times faster rotational speed than conventional
-1
ball screws. They handle speeds up to 5000 min . This capability
dramatically expands the range of service conditions.
Note: Please refer to the dimension table for details of permissible rotational speed.
Grease fitting provided as standard equipment
The new ball screws are equipped with a grease fitting (M5 × 0.8). Lubrication
ports are provided in two locations to facilitate maintenance.
The ball screws can be easily connected to an integrated lubrication system.
* Grease fitting provided on the flange OD when equipped with K1™.
New type of contact seal
A new high-performance contact seal minimizes grease dispersion
and helps to maintain a clean work environment.
Extended product life
K1™ Lubrication Units, in combination with minimal grease, offer increased
product life and maintenance-free operation. K1™ Lubrication Units are
particularly useful in applications where lubrication is difficult to apply
or is a source of contamination. The K1™ Lubrication Unit is optional
on the Compact FA series and is not available in two-week lead time.
Contact NSK for more information.

& Silent
Low-profile design
The low-profile support
units specifically compatible
with the Compact FA series
are available for a uniquely
space-saving design.

Precautions
Design
(1) If a ball screw of which the left shaft end (opposite driven side) is Shape I and is supported by the
“fixed-fixed’’ supporting method, you should be aware that the operating life of the support bearings may
decrease due to thermal expansion of the screw shaft, depending on usage conditions. In this case, you should
consider a structure that can absorb thermal expansion of the screw shaft if necessary. Please consult with
NSK for a detailed examination.
(2) If using an NSK linear guide, the maximum speed of a linear guide of standard specifications under ordinary
conditions is limited to 100 m/min. A linear guide with high-speed specifications is available if higher operating
speed is required. Contact NSK for further information.
(3) For general precautions concerning ball screws, please see NSK Catalog No. E3161 ‘‘Precision Machine Components’’.
Usage and handling
Ball screws are precision products and should be treated as follows:
[Lubrication]
(1) Compact FA Series ball screws are packed and coated with lubrication grease at the factory
and require no further lubrication under ordinary circumstances. If the surface of the grease
becomes contaminated with dirt and metal powder under operation, clean it with white
kerosene and replenish with new grease of the same kind through the oil hole (grease nipple)
on the ball nut. Avoid mixing different types of grease.
(2) Lubricant should be checked after the first two to three months of operation. If excessively
dirty, we recommend you wipe away the old grease and replenish with a generous quantity
of grease. After that, grease should be checked and replenished once a year under ordinary
circumstances, but the period may vary depending upon the service environment.
[Handling]
(1) Never disassemble the ball screw, otherwise dirt may contaminate the inside of the
unit and affect precision or result in equipment failure.
(2) Compact FA Series ball screws incorporate a new ball recirculation system.
Consequently, only NSK authorized plants should conduct disassembly and
reassembly. If the nut accidentally comes off the screw shaft or is dropped, NSK
will check precision, problems or perform repairs at your expense.
(3) When the ball screw is erected upright, the screw shaft or nut could fall by the force of its
own weight and result in injury. If dropped, the ball grooves could be dented or recirculation
parts damaged, resulting in loss of function. This would require the ball screw to be
inspected by NSK. If so, be sure to send the ball screw to NSK and we will check it for a fee.
[Usage]
(1) Ball screws should be used in a clean environment. The ball screws should be provided with
a dust cover to prevent the entry of debris such as dust and metal powder. If foreign matter
is allowed to contaminate the ball screw, this could not only cause the ball screw to lose
some of its function, but also result in clogging and damaging the recirculation system parts,
or cause the table to fall or a similar serious accident.
(2) Compact FA Series ball screws are designed to be used in a service temperature
environment of 80˚C or lower. Do not allow the service temperature limit to be exceeded.
In some cases, using ball screws in temperatures above 80˚C might lead to damage of
recirculation system parts or seal parts. Contact NSK if 80˚C must be exceeded.
Compact FA Series options
Consult with NSK for information about optional specification not given in the catalog
such as shaft end machining, reverse direction ball nut, alternative grease, surface
treatment, alternative preload or alternative threaded lengths.

Low-profile Support Units for Compact FA Series
NSK has developed a series of low-profile support units to be used with the ball screws
of compact FA series. A combination of the ball screw and the support unit offers a
compact design for the downsizing of many kinds of machinery.
Features
The low-profile support units offer the low center height construction suited for the compact FA series ball screws.
Product configuration
All parts required for ball screw mounting are provided as a set (see the table below). The bearing housing of the fixed side
support unit contains a built-in angular contact ball bearing and oil seal and should not be disassembled.
