- Product Description
High-Performance Robotics Bearings for Industrial Automation
Modern industrial automation demands exceptional precision and reliability from every component. Robotics bearings serve as the critical foundation for smooth, accurate robotic motion across manufacturing, medical, and aerospace applications. These specialized components must withstand continuous operation while maintaining tight tolerances under varying loads and environmental conditions. At Luoyang Precision Bearing Co., Ltd. (PRS®), we engineer products that deliver consistent performance for your automated systems.
Understanding Robotics Bearing Technology
RE Series Crossed Roller Bearings
The RE series represents our core products solution for applications requiring high rotational accuracy. This design features:
Structure Configuration:
- Integral outer ring construction
- Split inner ring design (two-piece assembly)
- Crossed roller arrangement at 90-degree orientation
- Optimized contact geometry for multi-directional loading
Working Principle:
The crossed roller configuration allows simultaneous handling of radial, axial, and moment loads through a single bearing unit. Split inner ring construction enables easy installation while maintaining outer ring accuracy for precise shaft positioning.
Performance Advantages:
- 3-4 times higher stiffness compared to angular contact ball bearings
- Bidirectional axial load capacity
- Reduced overall system complexity
- Enhanced moment load resistance
Thin Section Ball Bearings
For space-constrained robotic applications, our thin section bearings provide:
| Parameter | Specification |
|---|---|
| Inner Diameter Range | 20mm - 600mm |
| Outer Diameter Range | 36mm - 700mm |
| Section Height | 8mm - 40mm |
| Seal Configuration | Double-sided seal |
| Precision Grades | P5, P4, P2 available |
These bearings reduce overall robot weight while maintaining structural integrity, enabling faster acceleration and improved energy efficiency.
