Bearing other than quality, is also a very precise parts, both as a high-performance KOYO bearings, if you use improper use, not only does not meet expected performance results, and are vulnerable to bearing damage, in terms of lubrication must have attention.
Prevent corrosion of the bearing by hand when taking bearings directly, full hand washing liquid, and coated with high quality mineral oil before operation, paying particular attention to rust in the rainy season and summer. In some special operating conditions, KOYO bearings can get a life longer than traditional calculation, especially under light load conditions.
Under proper use, the bearings, can have very long life. if injury occurs prematurely, is most likely the selection error, caused by improper use or poor lubrication.
Therefore, when installing the KOYO bearings, we need to record the machine type mount, use conditions and tie around. Research Summary by type of bearing damage, use environment when a problem occurs in order to prevent the recurrence of similar situations.
Accurate control of cutting fluid concentration, when machine shutdowns, and use cutting fluid flush with surface of machine tools and machine cover to open, moist air to disperse the machine working area. To prevent galvanic corrosion occurs on the metal surface with a layer of waterproof lubricant. And the machine should be strictly grounded alone is not enough to ground the electrical cabinet, to prevent bacteria from breeding and reproduction, should be cleaned or replaced periodically cutting fluid, clear cutting in a timely manner, and to use soft water (pure water with low mineral content) of diluted cutting concentrate.
