RA Series Crossed Roller Bearings

RA Series Crossed Roller Bearing

Ultra-Thin Structure, High Precision, and Lightweight Design- Separable Outer Ring Type for Inner Ring Rotation

• RA series crossed roller bearings,
• RA-C series crossed roller bearings,
• CRBS series crossed roller bearings

 

The RA Series Crossed Roller Bearing is a high-precision rotary bearing developed for applications requiring minimal installation space, low weight, and smooth rotational accuracy. As an upgraded design from the RB type, the RA series features a reduced cross-sectional thickness while maintaining the same internal structure and high load-carrying capacity. This makes it ideal for compact and lightweight equipment where precision and rigidity are essential.

Key Features

Ultra-Thin and Lightweight Design:
The RA bearing has the thinnest cross-section among all crossed roller bearing types. Its compact profile allows installation in limited spaces without compromising rigidity, making it ideal for miniaturized precision systems.

High Rotational Accuracy:
Cylindrical rollers are arranged alternately at 90°, allowing the bearing to support radial, axial, and moment loads simultaneously with minimal friction. This cross-roller structure ensures high precision and smooth rotation even at varying speeds.

Excellent Rigidity and Stability:
Despite its slim structure, the RA series maintains high stiffness due to optimized internal geometry and precision machining. It performs reliably under combined loads and ensures consistent motion accuracy.

Low Friction and Long Service Life:
The precision-ground raceways and optimized roller alignment reduce frictional resistance, noise, and wear, leading to long-term stable performance even in continuous operation.
