Key Features of CRBH Series Crossed Roller Bearings

1. Multi-Directional Load Capacity

The CRBH series is designed to simultaneously support radial loads, axial loads, and moment loads, thanks to its unique orthogonal roller arrangement. This makes it ideal for precision mechanisms that encounter complex forces during operation.

2. One-Piece Ring Design for High Rigidity

Both the inner and outer rings of CRBH bearings are machined from solid, single-piece materials. This structure provides exceptional rigidity and contributes to high rotational accuracy while minimizing the impact of installation errors.

3. Thin-Section Profile

The CRBH series features a compact, thin-section design, making it especially suitable for applications with limited installation space. Despite its compactness, it offers excellent load capacity and performance stability.

4. No Mounting Holes – Flexible Installation

Unlike face-mount types, CRBH bearings are produced without mounting holes. This provides installation flexibility, allowing for customized mounting methods depending on the equipment design. The structure supports rotation of both the inner and outer ring.

Applications of CRBH Crossed Roller Bearings

Due to their high rigidity, compact design, and precision performance, CRBH series bearings are widely used in:

Industrial robot joints and rotating actuators
Rotary tables and indexing equipment
Medical equipment requiring precise movement, such as CT and MRI scanners
Radar and satellite communication devices
Rotary tools in CNC machines and automated systems
