Q: Why Do You Need to Set Bearing Clearance

A: 

The internal clearance of the bearing is closely related to the life, temperature rise, vibration, and noise of the bearing. Including radial oil gap and axial oil gap. The radial oil clearance is divided into five groups of 2, 0, 3, 4, and 5. Group 0 is the basic clearance, and its value increases sequentially.
