The bearing clearance plays an important role in the use of the process of the bearing, the bearing clearance is not working properly, then, will directly affect the efficiency in the use of the bearing, the general situation, bearing in the safe operation of the state, running slightly negative clearance when the maximum bearing life. But in practice it is very difficult to maintain this optimal state once certain conditions of use is changed, the negative clearance is increased, thereby incurring a significantly reduced bearing life or fever. So usually select the initial clearance, the running clearance is taken to be only slightly greater than zero.
Bearing under normal conditions, the ordinary load with speed and temperature normal, simply select the corresponding ordinary clearance, to make available the appropriate operating clearance. Since the bearing clearance bearing is very important, so we are in the process of using the bearing should pay more attention to the normal use of the bearing clearance, so as not to affect the normal use of the bearing due to the bearing clearance is not working properly, serious but also affect the bearing life, should cause us great emphasis.
