General motors at 2000 hours after the use of cleaning and oiling. There are two kinds of methods for cleaning bearing:
A hot oil cleaning method, due to prolonged use, soft stem bearing the anti rust oil or cream should be hardened, immersed in the hot oil 100 - 200 ℃, pliers with bearing, oil brush brush clean bearing. Do anti rust oil or soft paste was 100 - 200 ℃ heating to melt, easy from the bearing gap scouring out. Sometimes as long as the bearing in oil repeatedly shaking. Oil will flow through from the crevice.
In the spherical bearing cleaning the old motor or import motor, should take the ball, bead frame, the inner ring in the horizontal transfer from after immersion in hot oil, short cylindrical roller bearing cleaning should also roller, bead frame, the inner ring and the outer ring off.
In hot oil cleaning, oil temperature should not exceed 20 ℃. If using direct fire heating, care should be taken to prevent the burning of oil, the bearings should be hung in the pan, the bottom will cause overheating and reduce the hardness.
Two, like cleaning the bearing soaked in kerosene 5 - 10 minutes, hand pinch the inner ring, the outer turning the other hand, the bearings on the anti rust oil or cream do you fall down. Then the bearing into the oil cleaner, the use of soft scrub brush, put the ball and in the gap of the oil washed clean, then put 1 gasoline, remove and place them on a clean sheet of paper. Spherical ball bearings and cylindrical roller bearing cleaning when the ball, bead frame, the inner ring and the outer ring was torn off and cleaning.
