Introduction Of Cross Roller Bearing
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.
Features Of Cross Roller Bearing
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 hanges .
7. Nylon spacer, low inertia, low starting torque, easy to control angle indexing
8. Optimization of preload, rigidity, high precision guide rollers running
9. Carburizing steel provides excellent impact resistance and surface abrasion resistance
10. Simple but adequate lubrication
