Why does the sliding bearing use clearance fit?
The shaft should be rotated inside the sliding bearing without the clearance fit.
This is different from the rolling bearings, the shaft and rolling bearings of the inner ring is interference fit, because the shaft should be rolling bearing with the inner ring together to rotate.
Sliding bearing is a sliding, if the excessive interference or with great friction, will hinder the movement of cars bearing, and the wear is serious, is not conducive to the long-term use of parts.
