RU42 High Precision Crossed Roller Bearing
RU 42（Integrated Inner/Outer Ring type） Since the mounting holes are provided, the model does not require a presser flange or housing. In addition, because it has an integrated inner/outer ring structure and is equipped with washers, its performance is minimally affected by the mounting procedure, ensuring stable rotation accuracy and torque.
RU42 can be used for both inner-ring rotation and outer-ring rotation.
Bearing characteristics:
1. High precision: P4 precision, P2 precision
2. Radial clearance:CC0: Negative clearance(preload) C0:Positive clearance
3. Fixing hole\'s direction:
Blank: the inner ring and outer ring both are counter bores and in the same direction.
G:the inner ring and outer ring both are counter bores but in opposite direction.
X: The outer ring is counter bore and the inner ring is thread holes(through holes)
Used for RU124~RU445
RU42~RU85 if no mark, the outer ring has counter bore and the inner ring has through-hole
APPLICATION:
widely used on high precision rotary table, robot joints, rotating units, sophisticated medical equipments, and measurement instruments.
