RU124 Crossed Roller Bearing – Smooth, Precise, Low-Torque Design
The RU124 crossed roller bearing features spacers between vertically arranged rollers, preventing tilt and friction while reducing rotational torque. Its two-part inner or outer ring allows adjustable clearance, enabling high-precision rotation even under preload.
Why Choose RU124:
- Smooth Rotation: Spacers reduce friction and prevent roller tilt
- High Precision: Adjustable clearance ensures accurate movement
- No Roller Locking: Advanced design eliminates contact issues
- Reliable & Durable: Ideal for demanding industrial and precision applications
Applications: Robotics, rotary tables, precision machinery, medical equipment, aerospace systems

The difference between G and X:
G: the mounting holes on the inner and outer rings are counterbored, and the countersunk direction is the opposite.
X: the mounting holes on the inner ring are threaded holes, and the mounting holes on the outer ring are counterbores.
