Second, check the bearing have chewed and wear; Check the bearing inner and outer ring, rolling body, maintains its smoothness and presence of cracks on the surface of the discoloration, rust, peeling, pits, overheating defects, such as excessive measuring bearing clearance; Look for wear, pit shaft sleeve, peeling, if there is more than a new bearing should be replaced. Bearing with the bearing installation bearing inside diameter and shaft, with the outer diameter and the shell is very important, when cooperate with too loose, mating surface will produce relatively sliding as the creep. Once produced will wear matching surface, creep damage shaft or shell, and wear into the bearing internal powder and fever, vibration and damage. Interference is too big, can lead to small outer diameter or inner circle diameter, reducing the bearing internal clearance. For selecting suitable for purposes of bearing, want to consider the nature of bearing load, size, temperature condition, the rotation of the inner ring outer shape various factors.
