RU85 Crossed Roller Bearing – High Precision, Easy Installation
The RU85 crossed roller bearing features an integrated inner and outer ring with mounting holes, eliminating the need for a fixed flange or support seat. This ensures stable rotation, reliable torque, and allows both rings to rotate independently.
Why Choose RU85:
- Quick Installation: Built-in mounting holes save time and space
- Stable & Precise: Maintains high rotational accuracy under load
- Flexible Operation: Inner and outer rings can rotate as needed
- Durable Design: Long-lasting performance in precision machinery and industrial applications
Applications: Robotics, rotary tables, machine tools, automation systems, and precision equipment

Features:
1. With high rotation accuracy, the RU series crossed roller bearings produced by Tedin Bearings can provide negative clearance types with accuracy levels of P5/P4/P2
2. Installation is simplified. RU cross roller bearings have mounting holes in the inner and outer rings, and no fixed flanges and support seats are required during installation. In addition, since the inner ring and outer ring are of an integral structure, the installation has almost no effect on accuracy and performance, so stable rotation accuracy and torque can be obtained, which is suitable for the occasions where the outer ring and the inner ring rotate at the same time.
3. It can bear large axial and radial loads at the same time.
4. Significantly save installation space, reduce shaft length, and processing cost.
5. Adopt nylon divider, low moment of inertia, low starting torque, easy to control angle indexing.
6. Optimized pre-tightening force, strong rigidity, and high precision of guiding roller operation.
