Applications of CRB Series Crossed Roller Bearing
CRB series crossed roller bearings; the outer ring is divided into two pieces; the inner circle is an integral structure, and it is most suitable for the occasion where the inner circle has high rotation accuracy. This type of bearing is widely used in industrial robots, work machinery, medical facilities, etc., where high rigidity, tightness, and speed can still ensure accuracy.
Product process and test
1. Surface: Make sure the machine is cooled, and control the surface bending and parallel difference. Pickling flaw detection for the first product to see whether there is burning damage or crack.
2. Outer ring: Control ellipse, triangle, and size. Repeated grinding if it is high.
3. Inner ring: Control ellipse, wall thickness, and taper. The vertical difference should meet the requirements if it is high.
4. Raceway: Because of the particularity of this product, it needs to grind at a fixed distance and ensure that cooling is in place.
