SKF Miniature Bearing Deep Groove Ball Bearings for Sliding Doors Processing form

The processing forms of deep groove ball bearing parts are as follows:

1. Multi-process processing: Generally, bearing production requires 20 to 40 processes, and as many as more than 70 processes.

2. Forming processing: The working surfaces of bearing parts are all rotary forming surfaces, which are suitable for processing by forming methods.

3. Precision machining: Most of the surfaces of bearing parts must be ground, and the grinding dimensions and geometric accuracy are measured in μm.
