SKF bearing the preparing work before installation

SKF bearing cleaning steps: first, SKF bearing will be removed when checking, with photography method such as first and then record the appearance. In addition, to confirm the amount of residual lubricant and lubricant sampling, and then clean the bearing. This is a list of the bearing cleaning process: 1, SKF bearing points of cleaning the rough washing and fine washing, can be put in use at the bottom of the container and on the metal frame. Coarse, washing oil using a brush to remove grease or adhesive. If at this time in oil bearing, pay attention to the rolling surface due to foreign bodies such as damage. Fine cleaning, slowly rotating bearings in the oil, must be carefully. Bearing cleaning of note: 1, the use of cleaning agent for neutral aqueous diesel or kerosene, according to the need to sometimes use warm lye, etc. No matter use which kinds of detergent, often should filter clean. 2, after cleaning, immediately on the SKF bearing coating anticorrosive oil or antirust grease. Bearing under 3, in order to determine whether to use, to inspect the dimension precision, rotating accuracy, internal clearance and mating surface, raceway surface, cage and seal rings etc. Judgment standard according to the mechanical properties and important degree and inspection cycle. If you have the following injury, bearing shall not be used again, must be replaced. ( 1) Before the SKF bearing 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 SKF bearing installation difficulties and make the installation position is not correct, and solid particles such as falling into a SKF bearing inner grinding effect, when SKF bearing rotating grinding or bruising SKF 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 SKF 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 SKF 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, 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.
