First, pay attention to installation force. If there raceway pit pressure interval, indicating that the load is beyond the elastic limit. This is due to static overload or severe shock (such as tapping with a hammer during installation of bearings, etc.) caused. The correct installation method is only to be press-fit force of the loop (the inner ring mounted on the shaft when not to push the outer ring).

Second, pay attention to the mounting direction angular contact bearings. Angular contact bearings with an elliptical contact area, and only in one direction on the axial thrust. In the opposite direction when the bearing assembly, due to the ball raceway at the edge of the loading area will have its groove worn belt. Therefore, the installation should pay attention to correct installation direction.

Third, pay attention to the. Ball deflection traces of wear and tear, not the direction parallel with the raceway that is not installed on the bearing. If the skew amount> 16000, the bearing temperature rise and lead to serious wear and tear. Its causes may be bent shaft, shaft or box there are glitches, lock the clamping surface of the mother is not with the axis perpendicular to the other thread. Therefore, the installation should pay attention to check the track jump situations.

Fourth, we should pay attention to the correct match. Bearing, the outer circumference of the assembly-like contact surface appears worn or discolored, by bearing their match with loose parts caused. Abrasion produced by a pure brown oxide abrasive, and the results will cause further bearing wear, heat and noise and produce a range of issues such as track skip, so the assembly should pay attention to the correct match.

Another example is a serious bottom roller ball wear track, indicating that the match tight due to the bearing clearance becomes smaller, and the torque increases, the bearing temperature rise due to bearing wear and fatigue soon lapsed. At this point, as long as the appropriate recovery radial clearance, reducing the amount of interference can solve this problem.
