CRB Series (Integrated Inner/Outer Ring Type) Crossed Roller Bearing

I. Structural Characteristics

Split Outer Ring and Integral Inner Ring Design

• The outer ring is divided into two parts, while the inner ring is a single-piece structure, facilitating installation and clearance adjustment.
• Features an equal cross-section thin-walled design, with both inner and outer ring thickness minimized to suit compact space applications.

Rolling Element Arrangement

• Cylindrical rollers are arranged in a 90° cross pattern, with spacers maintaining their spacing to prevent friction and locking phenomena.

II. Performance Advantages

High Load-Carrying Capacity

• Capable of simultaneously withstanding radial, axial loads, and overturning moments, making it suitable for heavy-load applications (e.g., cranes, construction machinery).

High Rigidity and Precision

• Offers 3-4 times higher rigidity than traditional bearings, with rotational accuracy reaching P4 and P2 levels, ideal for precision equipment (e.g., CNC machine tools, medical instruments).

Lightweight and Compactness

• Extremely thin walls and reduced weight make it suitable for weight-sensitive applications such as robotic joints and manipulators.

High-Speed Performance

• Low-friction design supports high-speed rotation (e.g., DD motors, high-speed indexing tables).
