High temperature FAG bearing the preparing work before install

Requires both high rigidity, high temperature bearing shaft bearing system requires quality light, as far as possible in order to overcome the contradiction, can take measures such as reducing the surface roughness and improve the surface strengthening the support stiffness, in order to improve the use of hollow shaft to reduce the system quality, etc. ( 1) In the high temperature bearing before 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. ) 。 ( 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 FAG bearing installation difficulties and make the installation position is not correct, and solid particles such as falling into a high temperature bearing inner grinding effect, when FAG bearing rotating grinding or bruising high temperature 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 FAG bearing 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. ( 5) When cleaning a lot of high temperature bearing, first with a temperature of 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 old oil, then pour hot for a few minutes, then rinse with kerosene oil, clean with gasoline again finally. After washing clean, on film gloves should be worn to FAG bearing on the worktable of dry clean cloth or paper. ( 6) Note with high temperature bearing seal do not clean with this law, the seal of the internal cleaning should remain the same.
