NTN cylindrical roller bearing need to do what preparation work before installation

( 1) Prior to installation, should be in NTN cylindrical roller bearing with 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 the 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 NTN cylindrical roller bearing in installation and the installation location is not correct, and solid particles such as falling into NTN cylindrical roller bearing inner grinding effect, when NTN cylindrical roller bearing rotating grinding or bruising NTN cylindrical roller 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 NTN encapsulating cylindrical roller bearing, 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 NTN cylindrical roller bearing, with the first 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. After washing clean, on film gloves should be worn to NTN cylindrical roller bearing on the worktable of dry clean cloth or paper. ( 6) Note NTN cylindrical roller bearing with seal do not clean with this law, the interior of the seal should remain the same do not wash.
