KOYO rolling mill bearing installation quality of the service life of the important influence

KOYO bearing before installation should be clean. When installed, you should use the special tool to auxiliary sell straight uniform pressure into the, don't use hammer percussion, specifically prohibit direct tapping on the rolling mill bearing. When bearing race with a hole loose, should be to repair or replace the bearing seat holes, do not use on the surface of bearing with pitting or pad barely use copper method. Rolling mill bearing removal should be used when appropriate to pull pull the bearing, do not use a chisel, hammer percussion bearing, etc. To KOYO bearing installed on axis, he has to remove the bearing a coat of fixed pin, the shaft neck at the same time clean exterior burnish is smooth, and in the shaft neck oil anti-rust and lubrication ( Allows for a slightly bearings on the shaft rotation) 。 Coating on surface of the bearing and the bearing lubricant, bearing load bearing. Pushed to the required location for installation. Fixed bearing bolts do not tighten, let KOYO bearing coat rotation reaction in the bearing seat. Also installed on the same axis and on the other side of the bearing, axis, turn a few laps, automatic alignment position for rolling mill bearing itself. Then good bearing bolts. Eccentric sleeve. The eccentric sleeve installation is firm, finally lock eccentric sleeve on the socket head cap screw. KOYO bearing two kinds of commonly used lubricants lubricating oil and grease. When the peripheral speed of the shaft is smaller than 4 - 5 m/s, or the car cannot be used lubricating oil, lubricated by grease. Grease lubrication sealing structure of the method is simple, the grease is not easy to drain, little affected by temperature, plus a grease can use a long time. The normal working of rolling mill bearing should be uniform, smooth, not harsh voice instead of the normal working of KOYO bearing has a wide variety of intermittent, impact or harsh voice. First have to get used to the normal working of bearing ring, and then you can grasp the judgment is not normal working of bearing, and then through the accumulation of practical experience, and further can analyze what kind of what kind of bearing abnormal sound corresponds to the abnormal phenomenon. KOYO bearing abnormal sound a lot of categories, it is difficult to talk, mainly by experience accumulated.
