The Brief Description of Cross Roller Bearings:

Their rollers between the inner ring and the outer ring, the interval to intersect at right angles to each other are arranged. They can withstand the load from all directions (eg axial thrust load or momentum, etc.). Because the surface of the roller and the track into a linear contact and therefore, the bearing load and by the possibility of elastic deformation is small. This type of bearings are widely used in industrial automation, such as robots, machine tools and medical facilities, and need high rigidity, high speed close and still ensure accurate the occasion.

Bearing features:

1. High precision: precision at P4, P2.

2. High rigidity: this series bearings are with preload.

3. High load capacity: this series bearings can support axial load, radial load, and tilting load.

4. Small volume: this series bearings can save space for the machine.

Cross Bearing Advantages:

1. with excellent rotational accuracy

2. Installing simplifies operation

3. Bear large axial and radial loads

4.Significant savings in installation space

5. High speed capability

6. Shaft length and reduce processing costs, the geometry of thermal expansion is limited to changes .
