In a new buy bearing above, the vast majority are coated with grease. Oil and grease used to prevent the bearing from rust, does not act as a lubricant, therefore, must be thoroughly cleaned in order to install and use. The method of cleaning is: Where anti-rust oil-sealed bearing can be used as gasoline or kerosene cleaning. Where thick oil and antirust oil petroleum jelly anti-rust bearings, such as industrial use on the 10th heating of the oil or transformer oil dissolved cleaning (oil temperature must not exceed 100 ° C), the bearings are immersed in oil. People to be anti-rust grease melted out and cool, then gasoline or kerosene to clean. Where gas agents, anti-rust water and other water-soluble rust-proof materials, anti-rust bearings, available soap cleaning agent, such as 664, perusal, 6503, 6501 cleaning agent.
Use gasoline or kerosene cleaning, first-hand pinch the bearing inner ring, the other hand, slowly turn the outer ring, until the rolling element bearings, roller, cage the oil is completely washed off, and then cleaning the surface of the net bearing outer ring . Cleaning should also be noted that, at the beginning should be slowly rotating, reciprocating, rocking, and shall not use excessive force on the rotation, otherwise, the bearing raceway and rolling element is easily attached to the dirt damage. Large number of bearing cleaning, in order to save gasoline, kerosene and to ensure the quality of cleaning can be divided into coarse and fine cleaning in two steps.
