Needle Rollers
No backlash in any direction since Shaft / Bushings are 1 ~
6µm of preloaded.

Retainer
Made from one-piece casting of super
engineered plastic.
d1 Through Hole
High accuracy needle rollers are arranged in four directions against the square shafts.
Shafts / Bushings are designed to be 1 ~ 6µm preloaded.
Widely used in parts of semiconductor, liquid crystal manufacturing equipment and inspection device, lift / slide stages, robotic systems, press machines and
transfer mechanism as the guide with high rigidity, straightness and high speed.
Capable of torque loading without rotation due to square cross section with low yawing and pitching, maintaining smooth rotation and stable accuracy.

QCautions
323
-Administer lubrication maintenance as needed.
-When designing, position the bushing where the retainer does not fall out from the bushing at stroke ends.
-As the preload is still applied when inserting retainers, assemble and fit carefully in order not to apply any off-center insertion force as that may cause the damage to the retainers as well as damages on the rolling surfaces.
-Protect it with covers if any foreign objects or dust may adhere to the rolling surfaces.
-Avoid using in high temperature environments, keep below 80°C.
-Do not cold shrink fit the bushings and shafts.
Residual austenite will transform into martensite and will expand inner / outer dimension of bushings and shafts, rendering them unusable.
