First, heat the oil cleaning method because prolonged use, soft dry oil or rust paste hardened bearings, should be soaked in hot oil in 100-200 ℃, bearing with pliers, hair brush with a clean oil on the bearings. Soft dry oil or rust cream is heated to 100-200 ℃ to melt, it is easy from the cracks in the wash out of bearings. Sometimes as long as several times in the oil bearing rock. Oil will go from the gap.
In cleaning the old motor or imported to the spherical bearing motor, it should be the ball, bead frame, the inner from the outer lateral roll-out and then immersed in hot oil in a short cylindrical roller bearings roller should be cleaned when , bead frame, inner and outer ring torn off.
In the hot oil cleaning, oil temperature should not exceed 20 ℃. If the direct heating with open flame, should be taken to avoid burning the oil, the bearing to fly in the pan, sink to the bottom will cause overheating and reduce the hardness.
Second, as bearing on the kerosene cleaning method to soak 5-10 minutes in one hand and pinch the inner ring, outer ring rotating the other hand, bearing on the anti-rust oil or cream will dry fall. Then the bearing into the cleaner kerosene, scrub with a soft brush, the ball and clean oil within the gap, and then washed 1 into the gasoline, removed and placed in clean paper. To the spherical ball bearings and cylindrical roller bearings will be washing ball, bead frame, the inner and outer ring torn off cleaning.
Mounted on the shaft bearing cleaning, mainly by pouring oil or oil spray gun method, easily washed off the oil after the first use of petrol with kerosene; difficult cleansed of oil, first with100-200 ℃ hot oil washing or spray gun oil, gasoline and then wash. Be careful not to use sharp tools to scrape bearings: a hard knot of grease or rust, so as not to damage the bearing rolling elements and parts of the ring groove finish, clean the bearing with a clean cloth.
