SX series crossed roller bearings, this type has a smaller cross-section than the RB series in the same journal case. Due to the ultra-thin design, there are no mounting holes for the outer and inner rings, and flanges and supports are required for installation. It is suitable for cases where the inner ring rotates.

SX series crossed roller bearing application:
It is suitable for cases where the space is limited, where the high rigidity and hig rotation accuracy is required. Such as joint rotation parts of industrial robots, rotary tables of machining centers, precision rotary tables, medical equipment, calculators, and IC manufacturing equipment.
SX011880 Crossed Roller Bearing provides high and stable running accuracy.

This kind of Cross roller Bearing have the following features:
1.High precision: precision at P4, P2
2. with excellent rotational accuracy
3. Installing simplifies operation
4. Bear large axial and radial loads
5.Small volume: this series bearings can save space for the machine.
6. High load capacity: this series bearings can support axial load, radial load, and tilting load.
7. Optimization of preload, rigidity, high precision guide rollers running
8. Carburizing steel provides excellent impact resistance and surface abrasion resistance
9. Simple but adequate lubrication
