CRBH Series Crossed Roller Bearings
(Integrated Outer/ Inner Ring Type)
The inner ring and outer ring of the CRBH series crossed roller bearings are all integrated structure, their overall sizes are completely same with RB and RE series crossed roller bearings, but its outer ring have hole type structure for installing bearing rollers, so both the inner ring and outer ring can achieve high rotation accuracy, thus both the bearing inner ring and outer ring is available to rotating.
CRBH series crossed cylindrical roller bearings is mainly used for: rotation part of the machine tools, CNC rotary table, medical equipment, aviation equipment, precision turntable, etc.
Comparison of CRBH, RB, and RE Crossed Roller Bearings
| Feature | CRBH Series | RB Series | RE Series |
|---|---|---|---|
| Ring Structure | Both inner and outer rings are integrated (one-piece) | Inner ring integrated, outer ring split into two pieces | Outer ring integrated, inner ring split into two pieces |
| Mounting Holes | No mounting holes | No mounting holes | No mounting holes |
| Rotating Element | Both inner ring and outer ring can rotate with high accuracy | Inner ring rotates with high precision | Outer ring rotates with high precision |
| Rigidity & Accuracy | Very high rigidity and rotational accuracy due to integrated design | High rigidity, optimized for applications requiring inner ring rotation | High rigidity, optimized for applications requiring outer ring rotation |
| Design Flexibility | Offers greater design freedom since either ring can rotate | Best suited for designs where inner ring rotation is required | Best suited for designs where outer ring rotation is required |
| Applications | CNC rotary tables, medical equipment, aerospace, precision turntables | Machine tool spindles, indexing tables, robotics | Precision rotary mechanisms, measuring instruments, automation equipment |
Why Choose CRBH Crossed Roller Bearings?
CRBH series crossed roller bearings combine precision, rigidity, and flexibility in one compact package. Unlike conventional RB or RE bearings, the CRBH design allows both the inner and outer rings to rotate with exceptional accuracy, giving engineers and designers greater freedom in machine layout and system design.
Key Benefits for Your Applications:
- Dual-Ring Rotation Capability: Either ring can rotate smoothly, ideal for CNC rotary tables, precision turntables, and automated machinery.
- Simplified Installation: Outer ring mounting holes reduce assembly time and ensure reliable positioning.
- High Load Capacity & Stability: Optimized roller alignment delivers excellent radial, axial, and moment load support.
- Versatile Across Industries: Perfect for machine tools, robotics, medical devices, aerospace systems, and other precision equipment.
By choosing CRBH bearings, you gain a high-performance solution that maximizes machine efficiency, ensures long-term reliability, and supports compact, high-precision designs.
