NSK bearing installation and disassembly techniques

A lot of people in the installation of NSK bearings use improper installation method, cause the damage of the bearing. So how to correctly install NSK bearings? Hope everyone more comprehensive understanding of the bearing installation and removal, installation, can according to its type and size, select machinery, such as heating or hydraulic method. But in any case, all can't knock directly bearing ring, cage, rolling body or seals. When installed on the bearing force, never can be passed on from a roller bearing ring to another bearing ring, otherwise it may cause damage to the race. For clearance fit the bearing ring, it is recommended that the fitting surface with a thin layer of peristalsis etchant, in case of friction between mating surface corrosion. The correct installation, for the use of NSK bearings is very important. I hope you can in the later use with correct installation method. Series 390000, outer spherical bearing is through the eccentric sleeve bearing inner ring with fixed axis, eccentric sleeve on the socket head cap screw fastening effect. With Allen wrench to loosen the lock screw on the eccentric bearing sets, and then with a small iron rod inserted into the roof sink hole on the eccentric sleeve, against the direction of the axis of rotation to play loose eccentric sleeve. Unscrew the fixed bolt of the bearing. From the bearing, together with the bearing on the shaft will be unloaded. Should be on the other end of the shaft bearing bolt loosening, lest bearings on both ends don't strength and damage to each other. Before installation imported bearings on the shaft, you must first remove the bearing a coat of fixed pin, the shaft neck at the same time clean exterior burnish is smooth, and shaft neck with anti-rust and lubrication oil ( Allows for a slightly bearings on the shaft rotation) 。 Coating on surface of the bearing and the bearing lubricating oil, put the bearing into the bearing seat. Pushed to the required location for installation. Fixed bearing bolts do not tighten, let bearing coat in bearing internal energy. Also installed on the same shaft, on the other side of the bearing and shaft turning laps, make automatic alignment position bearing itself. Then good bearing bolts. Eccentric sleeve. The eccentric sleeve installation is firm, finally lock eccentric sleeve on the socket head cap screw.
