SX Series Crossed Roller Bearings

SX Series Crossed Roller Bearings(Separable Outer Ring, Type for Inner Ring Rotation). Its structure is similar to RB series crossed roller bearings; the outer ring is separable and connected with three starting rings. At the same time, the inner circle is integrated with the main body. This model is used in locations where the rotation accuracy of the outer ring is required.

SX Series Crossed Roller Bearings

The SX series crossed roller bearings structure is similar to the RB series; the outer ring is separable and connected with three locating rings. At the same time, the inner circle is integrated with the main body. This model is used for occasions where the rotation accuracy of the outer ring is required.

Advantages compared to other bearings:

1. Capable to easily assembled in all directions of the main shaft, mass production can be achieved through standardization and serialization, and assembly and use are more convenient.

2. Capable to bear both radial and axial loads at the same time, so crossed roller bearings can be much more simplified than multiple sets of combined bearing structures.

3. Due to the high rotation efficiency and low heat dissipation of crossed roller bearings, the grease consumption is small.
