Many customers will ask, what are the reasons for the overheating of angular contact ball bearings? Summarize the following main factors for you: 1) The incorrect installation position of the bearing will increase the axial force between the end face of the ball and the inner ring and the outer ring stopper of the bearing seat, which may increase the heat of the bearing. Therefore, when installing an angular contact ball bearing, it is not allowed to directly strike the bearing, and it is necessary to ensure that the bearing force is kept uniform; 2) When selecting an angular contact ball bearing, a bearing with appropriate precision should be selected according to the application scenario; 3) Spindle problem If the bearing is overheated, it may be caused by the bending of the main shaft or unreasonable installation, which may cause the bearing to heat up. What we need to do is to repair the main shaft; 4) An important reason for the overheating of angular contact bearings is that the bearing space is relatively precise and the clearance is relatively small. , so in order to avoid overheating of the bearing, we should choose a bearing with a suitable tolerance; 5) Improper lubrication will cause the bearing to heat up. When we buy angular contact ball bearings, we should use the specified brand of grease, and do not mix different greases. The general service life of grease is 90 days, and expired bearings cannot be used, otherwise it may cause the bearing to overheat; 6) Improper assembly of angular contact ball bearings may also cause the bearing to heat up; 7) If the bearing runs for too long, it will cause bearing-related components Abrasion will cause heating of the inner and outer rings of the angular contact ball bearing; 8) Excessive axial force of the bearing may also cause the bearing to heat up. We need to check the axial force of the bearing in time to avoid the problem of bearing heating; 9) Another reason is the heating caused by the damage of the angular contact ball bearing itself. At this time, the bearing needs to be replaced. The torque is accurate, the rotation can be stable, 37 years of precision angular contact ball bearing supplier!
