Comprehensive observation: NSK Bearings Rolling preparations before installation
(1) before NSK Bearings installation, you should use the proper measurement tools by drawing on the technical design requirements set out, check the shaft and housing bore machining quality and related parts (such as dimensional accuracy, shape accuracy and surface roughness, etc.). (2) on the mounting surface of the shaft and the bearing hole if bumps, burrs, rust or solid particles (such as grinding dust, sand, clay), etc. exist, not only will NSK Bearings difficult to install and the installation location is not correct, and solid particles such as NSK bearings will fall within an abrasive effect when NSK bearing rotation will work rubs or scratches the surface of NSK bearings, it must be checked carefully before installation, such as any of the above defects, should be amended . For example, by removing the oil filing burrs, projections touch marks, rust, and polish with fine emery cloth, and if the cleaning of solid particles, dirt and so on. (3) mounting surface should be cleaned with a clean gasoline, kerosene, toluene or xylene solution, such as clean and dry with a clean cloth, and then coated with a thin layer of oil, so make the installation more convenient. (4) Open NSK Bearings temporary installation package, it would be immersed in the above liquid gasoline to hand gently rotated to ensure that cage, rolling elements and raceway surface of the package to be cleaned thoroughly clean oil and the like. (5) cleaning a large number of NSK Bearings, first with a temperature of 90 ~ 100 ℃ hot oil poured hot oil to make the package to melt the same time with the mouth and not drop crumbs seamless tool to dig the net all the used oil, then pour hot a few minutes, then rinse with kerosene to oil, gasoline and then finally clean again. After washing clean, you should wear gloves NSK Bearings film on the clean table cloth or paper to dry. (6) Note with seal NSK Bearings unavailable Law cleaned, sealed inside should remain as non-cleaning.
