Key Features of SX Series Crossed Roller Bearings

1. Simultaneous Load Support

SX crossed roller bearings are capable of sustaining radial, axial, and moment loads at the same time. This versatility makes them suitable for complex systems where multi-directional stability is required.

2. High Rigidity and Precision

The use of three locking rings (instead of traditional screw fastening) ensures uniform pressure distribution and helps maintain bearing shape during operation. Combined with internal preload adjustment, this results in exceptional rotational accuracy and high rigidity.

3. Stable and Smooth Rotation

By optimizing internal clearance and eliminating structural inconsistencies, the SX series offers stable and smooth motion, even under varying loads and high-speed conditions.

4. No Mounting Holes – Flexible Integration

The SX series comes without mounting holes, allowing for greater flexibility in mounting design. This structure supports both inner and outer ring rotation and is ideal for installations where compactness and stability are essential.

Applications of SX Crossed Roller Bearings

SX crossed roller rings are especially suitable for high-precision equipment with limited installation space, such as:

Joints and swiveling units of industrial robots
Swiveling tables of CNC machining centers
Rotary actuators and robotic arms
Precision rotary tables
Medical imaging devices
Precision measuring instruments
Semiconductor and IC manufacturing machines
