Germany IVE bearings

The fit between the inner diameter of the bearing and the shaft, as well as the outer diameter and the shell, is very important during bearing installation. When the fit is too loose, relative sliding occurs on the mating surface, which is called creep. Once creep occurs, it can cause wear on the mating surface, damage the shaft or casing, and wear powder can invade the interior of the bearing, causing heating, vibration, and damage.
When the interference is too large, it will cause the outer diameter of the outer ring to decrease or the inner diameter of the inner ring to increase, which will reduce the internal clearance of the bearing. In addition, the geometric accuracy of the shaft and shell processing will also affect the original accuracy of the bearing ring, thereby affecting the performance of the bearing.
