Bearing Radial Clearance
The clearance is the distance between outer ring, inner ring and rolling element. It is an important factor that has significant influence on noise, vibration, heat and fatigue life of a bearing. As such, it is critical to select the proper clearance considering the bearing fit, load, speed and operating temperature. When measuring the internal radial dlerance, the bearing is subject to a standard load in order to ensure full contact between all bearing comonents. Under such a loa d, the measured clearance is larger than the actual; this is due to elastic defoma tion. The difference is compensated by the factors given in the table below.
