Product Introduction
The RU42 Crossed Roller Bearing is an integrated crossed roller bearing designed for compact precision rotary applications. Its cylindrical rollers are arranged alternately at 90°, allowing one bearing to support radial, axial and moment loads in multiple directions.
The RU42 features an integrated inner and outer ring with mounting holes, making installation easier without requiring a separate fixing flange or housing. It can be used for either inner-ring or outer-ring rotation and provides stable rotational accuracy and rigidity.
Applications
RU42 crossed roller bearings are suitable for:
- Industrial robot joints
- Precision rotary tables
- Indexing mechanisms
- Machine tool rotary units
- Inspection and measuring equipment
- Precision reducers
- Manipulator rotary mechanisms
- Semiconductor and automation equipment
Crossed roller bearings are particularly suitable where compact dimensions, high rigidity and multi-directional load capacity are required.
Product Advantages
1. High Rigidity
Cross-arranged cylindrical rollers provide strong resistance to radial, axial and moment loads.
2. Compact Structure
The RU42 integrates the inner and outer rings, helping save installation space.
3. Multi-Directional Load Capacity
A single bearing can handle radial, axial and moment loads.
4. High Rotational Accuracy
Suitable for precision rotary mechanisms requiring stable and accurate movement.
5. Easy Installation
Integrated mounting holes simplify installation and reduce the need for additional housing components.
