Analytic: NSK bearings cleaning installation considerations - bearing knowledge

( 1) Cleaning of NSK bearings, with temperature is 90 ~ 100 ℃ heat oil pour hot to melt encapsulated oil, at the same time with seamless all mouth and no net exfoliation tools to dig the old oil, then pour hot a few minutes, then rinse with kerosene oil, clean with gasoline last again. After washing clean, the NSK bearings on film gloves should be worn in to the worktable of dry clean cloth or paper. ( 2) NSK bearings in prior to installation, 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. ) 。 ( 3) NSK bearings installed in the open the package and 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. ( 4) 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. ( 5) Note with NSK bearing seal do not clean with this law, the seal of the internal cleaning should remain the same. ( 6) Shaft and the bearing hole assembly there such as bruising, burr, rust stain on the surface or solid particles ( Such as abrasive dust, sand, clay) NSK bearings such as existence, not only can make the installation difficulties and make the installation position is not correct, and solid particles such as NSK bearings will fall into the grinding effect, when NSK bearing rotating grinding NSK bearings or bruising of the 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.
