Because TINKEN bearing Angle contact ball bearing and tapered roller bearings in radial and axial internal clearance between a definite relationship, so, need to specify a numeric value can. General is designated to internal axial clearance. By the following method can then be from zero clearance from the state to a specified value: loosen or tighten the axis of stem nut or box in the ring when screw, or in a circle and its support bearing between calibration gasket or insert pads. Used to adjust the clearance and measurement set the practical method of clearance, depends on the amount of bearings for installation.
And other cylindrical aperture to bearing different, a single Angle contact ball bearing TIMKEN import and circular cone roller bearings internal clearance, only in a bearing on another bearing the adjustment to establish. Usually these back-to-back or face to face bearings is matching, one of the bearing axial displacement lap is, until it reaches the selected clearance or the load. Clearance or the load choice, depends on the performance of the layout of the bearing and the requirements of operation condition. The load bearing pre-loading detailed content, see "bearing the load control" section. Therefore, the following Suggestions involve Angle contact ball bearing and circular cone roller bearings of the bearing of the layout of the internal clearance adjustment.
Install proper clearance to value, can according to the load bearing temperature conditions and to determine. According to the size of the bearing and the layout, the shaft and bearing the box and two manufacturing materials bearing the distance between the initial clearance for in practical operation may become larger or smaller. For example, the temperature difference between the internal and external circle thermal expansion will cause the operation of the middle reaches of the gap narrowing, so the initial clearance must be quite large, can avoid timken bearing deformation and the adverse consequences.
There is a kind of method is used to remove in the wheel hub dial indicators, check the wheel bearing layout set axial clearance. The important thing is, in the adjustment of the tapered roller bearing and measuring TIMKEN import clearance, shaft or bearing box in different directions to rotate for weeks, and to ensure the ball at the end of the inner circle and the margin of the appropriate contact. If the contact inappropriate, the measurement result is not accurate, it cant reach the expected adjustment purpose
