SKF bearing installation method

For tapered hole SKF bearing, the installation of the inner ring always USES the interference fit. Unlike cylindrical hole SKF bearing, SKF bearing taper hole interference level is determined by the selected axis fit tolerance, but by SKF bearing in the cone shaft and shaft sleeve or withdrawal of the forward distance on the decision. SKF bearing radial internal clearance along with the advancement of SKF bearing on the cone shaft neck and narrow. By measuring the decrease value, the interference which can determine the degree of tightness and cooperate. Install the self-aligning ball SKF bearing, CARB toroidal roller SKF bearing, spherical roller bearings SKF bearing and high precision cylindrical roller with conical hole into the SKF bearing, to determine the radial internal clearance decreased value or cone base on axial forward distance, measure the amount of interference. Clearance decreased value and axial forward distance instruction, see related products. Small SKF bearing small SKF bearing can use nut, to advance to the cone base. In the case of the collar, then use the sleeve nut. Small sleeve nut available back into SKF bearing hole. Available to hook spanner or pneumatic wrench and tighten the screw as well. Before installation, should be on the surface of shaft and sleeve slightly a little oil. Large and medium-sized SKF bearing large SKF bearing the installation force increased significantly, and should use the hydraulic nut and/or filling method. The above two methods can significantly simplify the process of installation. Operating hydraulic nut and filling equipment for the oil injection method is used, there is supply. Detailed information about these products, see the line record the relevant part of the 'maintenance and lubrication products'. When using hydraulic nut SKF bearing installation, it must be positioned in the thread section of the journal or the sleeve on the thread of the ring piston abuts on the shaft of SKF bearing inner ring, nut or retaining ring on the shaft end. Through the pump oil into the hydraulic nut to safe and accurate force installation, move upward in axial piston. Spherical roller, using hydraulic nut, SKF bearing installed on the filling method is used, the oil under the high pressure injection of SKF bearing and shaft neck, forming a layer of oil film. This layer of oil film split mating surface, significantly reduce the friction between the mating surface. In the SKF bearing directly installed to the cone axis neck, generally in this way, but also used in specially designed for filling method to prepare the set of SKF bearing installed on set and pass the set. Oil pump or the necessary pressure lubricator, the groove on the shaft or sleeve and oil channel, the oil injection between mating surface. SKF bearing design layout, must consider the necessary groove is arranged in the shaft and the channel. Spherical roller SKF bearing installed on the grease groove of withdrawal, with the oil into the matching surface, and, in turn, tighten the screws, to press the withdrawal sleeve into SKF bearing hole.
