NSK bearings installed good or bad, will affect the accuracy of NSK Bearings, life and performance. Therefore, fully research the installation of NSK Bearings NSK Bearings installed in accordance with the standards of operation, including the following items. The NSK bearings have been greased and bilateral with seal or dust cover, seals NSK bearings before installation without washing. NSK Bearings shall be installed according to the nature of NSK bearing structure, size and NSK bearing components with pressure should be applied directly to the tight fit ferrule end face shall not pass through the rolling pressure, the NSK bearings installed generally use the following method:thrust bearing
a press-fit
The NSK bearing inner ring with the shaft of a tight fit, the outer ring and the the NSK bearing hole is more loose fit, available presses NSK bearings be pressed onto the shaft, then the shaft is loaded together with NSK Bearings NSK bearing hole press-fit in the the NSK bearing inner ring end face, to pad a soft metal materials to do the assembly sleeve (copper or soft steel), the assembly casing diameter should be slightly larger than the jo urnal diameter, outside diameter diameter than the NSK bearings within circle the ribs slightly smaller, to avoid pressure on the retainer. Tight fit the NSK bearing outer ring with NSK bearing hole, inner ring and the shaft is more loose fitting, NSK Bearings NSK bearing hole first pressed into At this assembly the outside diameter of the casing seat hole should be slightly smaller than the diameter of the . NSK bearing rings and the shaft and the housing bore is a tight fit, install indoor ring and the outer ring to be pressed into the shaft and the housing bore, the assembly casing structure should be able to charge tight NSK bearing end face of the inner and outer rings .angular contact ball bearing
b heating with
By heating NSK Bearings NSK bearing, thermal expansion will be a tight fit to change for the loose-fit installation method. Is a common and effortless installation m ethod. This method is suitable for the installation of the larger amount of interference NSK bearings before mounting the heat to of NSK bearings or separable NSK bearing ferrule into the tank in the uniform heating to 80-100 ° C, and then removed from the oil onto the shaft as soon as possible. After cooling on, is to prevent the inner ring end face and shaft shoulder fit is not tight, NSK bearing cooling axial fastening. Heating NSK bearing NSK bearing NSK bearing outer ring and light metal is a tight fit, hot charging method, can be avoided with the surface by abrasion. NSK Bearings heating with fuel tank in the tank away from a certain distance at the bottom should be a network gate or hanging with hooks NSK bearings, NSK Bearings can not be put on the bottom of to prevent Shen impurities into the NSK bearings or uneven heating, must have a thermometer, and strictly control the oil temperature must not exceed 100 ° C, to prevent tempering effect, reduce the hardn ess of the ferrule.ball roller bearing
installation of c. tapered bore bearings
Tapered bore bearings can be mounted directly on a tapered journal, or loading of tight on the sleeve and the the withdrawal sleeve of cone, with the tightness of available NSK bearing radial clearance reduction measure, therefore, the installation should measure the the NSK bearing radial clearance, the installation process should always measure the clearance in order to achieve the required clearance reduce the amount of up to installation usually locknut installation, also can be used to install heating method.
d. thrust bearing installation
The the comprehensive thrust bearing and shaft with generally transition fit seat with NSK bearing hole with general clearance fit this NSK Bearings easier to install, bi-directional thrust bearing central axis of the spring on the shaft fixed to to prevent rotation r elative to the shaft. NSK bearings installed, under normal circumstances, is the axis of rotation of the majority, and therefore for the inner ring and shaft with win match, the NSK bearing outer ring and NSK Bearings room with clearance fit.bearings high speed
