RU42 Crossed Roller Bearing – High Stiffness and Load Capacity
The RU42 crossed roller bearing (equivalent to CRBF2012ATUU) features an integrated inner and outer ring, providing exceptional stiffness and high load-bearing capacity. Its robust design ensures reliable performance in demanding precision applications.
Key Features:
- High Stiffness: Integrated ring structure enhances rigidity and stability
- Superior Load Capacity: Supports radial, axial, and moment loads efficiently
- Durable & Reliable: Engineered for long-lasting performance in industrial environments
Applications:
Widely used in industrial robot joints, rotary tables, reducers, CT scanners, machine tools, telecommunication equipment, radar systems, and other precision machinery.

Other models of the same series are as follows: RU42, RU6, RU85, RU124(G)/(x), RU148(G)/(x), RU178(G)/(x), RU28(G)/(x), RU297 (G)/(x), RU45 (G)
The difference between G and X:
G means that the mounting holes on the inner and outer rings are counterbored, and the countersunk direction is the opposite.
X means that the mounting holes on the inner ring are threaded holes, and the mounting holes on the outer ring are counterbores.
RU crossed roller bearings for manipulators are suitable for precision applications that require multi-directional load, such as robot arms, precision turntables, etc. The bearing itself adopts a negative clearance design, so the bearing is rigid enough to withstand larger loads and has higher accuracy (run-out is basically between 0.001mm and 0.01mm, bearing accuracy is above P5).
