Japan NSK bearing the preparing work before installation

A, NSK bearings in Japan 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. ) 。 Second, the shaft and bearing 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 Japanese NSK bearings in installation and the installation location is not correct, and solid particles such as falling into Japan NSK bearing inner grinding effect, when Japan NSK bearing rotating grinding or bruising Japan NSK bearing surface of the work, so must be checked carefully before installing, 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. Three, with clean the surface of the assembly shall be clean gasoline, kerosene, toluene and xylene solution clean, with dry clean duster cloth, and then coated with a thin layer of lubricating oil, which can make the operation more convenient installation. Four, when installed in the open the Japanese NSK bearings encapsulation, 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. Five, the cleaning of Japan 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 again finally. On film gloves should be worn after washing clean, Japan NSK bearings on the worktable of dry clean cloth or paper. Note with seal, Japan NSK bearings, not with the provisions of cleaning, the interior of the seal should remain the same do not wash.
