Motor bearings, which are mainly used in soft dry oil or antirust paste hardening, should be immersed in hot engine oil at 100m / 200 ℃, clamp the motor bearings with pliers and clean the oil on the motor bearings with brushes.

The soft dry oil or antirust paste melts when heated to 100 Mel and 200 ℃, and is easily flushed out of the gap in the motor bearing.

Sometimes as long as the motor bearing is shaken many times in the oil, the oil will flow away from the gap.

When cleaning the centripetal spherical motor bearing of the motor, the ball, bead frame and inner ring should be transversely turned out of the outer ring and then immersed in hot oil, and the roller, bead frame, inner ring and outer ring should also be separated when cleaning the bearing of the short cylindrical roller motor.

When cleaning hot oil, the temperature of the oil should not exceed 200 ℃.

If the direct heating with open fire, we should pay attention to prevent the oil from burning, motor bearings should be suspended in the oil pan, sinking will cause overheating and reduce hardness.
