Preparation of the rolling bearing before installation

( 1) Before the bearing is installed, should use the appropriate measuring tools according to the provisions of the technical requirements on the design drawing check the shaft and hole and machining quality of parts ( Such as dimensional accuracy and shape accuracy and surface roughness, etc. ) 。 ( 2) Shaft and hole assembly there such as bruising, burr, rust stain on the surface or solid particles ( Such as abrasive dust, sand, clay) Such as existence, not only can make the bearing installation difficulties and make the installation position is not correct, and solid particles such as falling into a bearing inner grinding effect, when bearing rotating grinding or bruising bearing surface of the work, so must be carefully checked before the installation, if found to have the above defects, should be revised. For example using oil file to remove burrs, bump touch mark, rusty spot, with fine abrasive cloth lighting, and like a clean solid particles, dirt, etc. ( 3) Should be assembled with clean the surface of the gasoline, kerosene, toluene and xylene solution washing clean, with dry clean duster cloth, and then coated with a thin layer of lubricating oil, it can make the operation more convenient installation. ( 4) When installed in the open the bearing assembly, put it into the liquids such as gasoline with handle gently gently turning, to ensure the cage, encapsulated oil on the surface of the rolling element and raceway thoroughly washed clean. ( 5) When cleaning a lot of bearing, with the first temperature is 90 ~ 100 ℃ heat oil pour hot to melt encapsulated oil, and there is no edge and does not use net exfoliation tools to dig all the old oil, then pour hot a few minutes, then rinse with kerosene oil, clean with gasoline last again. After washing clean, the bearing on film gloves should be worn in the workbench of dry clean cloth or paper. ( 6) Note with sealed bearing do not clean with this law, sealed internal cleaning should remain the same.
