HRB bearing clearance choice is reasonable or not directly determine the length of the bearing life. Choosing HRB bearing clearance, should consider the following aspects: 1, the bearing of the working conditions, such as temperature, load, speed, etc. ; 2, on bearing operational performance requirements ( Rotating accuracy, friction torque, noise, vibration) ； 3, bearings, the difference in temperature between inside and outside ring lead to bearing clearance decreased; 4, bearing and shaft and the shell hole for fit to the bearing clearance decreased; 5, due to the shaft and the shell material expansion coefficient is different, lead to bearing clearance decrease or increase; 6, according to the experience of the use, the ball bearing is the most suitable work clearance is zero; Roller bearings with a small amount of work clearance shall be maintained. Work clearance, refers to the bearing in the actual operation conditions of clearance. There is a clearance is called the original clearance, is refers to the clearance of the bearing before installation. Clearance is greater than the original installation clearance, clearance work less than normal clearance. Choice of clearance, the main work is to choose the appropriate clearance.
