Axis of the bearing inner ring and tight fit, the outer ring bearing hole is relatively loose fit of then on-separable type bearings installed, press the bearings can be installed on the shaft, then shaft with bearings mounted to the bearing bore with period, if the bearing is small, can also be used with soft metal hammer tap sets
Force the bearing ring to the end, but the percussion force to be evenly distributed in the bearing rings on.
Bearing outer ring and the bearing hole for the tight fit, the inner ring and the shaft to a more loose fit, it can be installed on the bearing shaft.
When the bearing ring and shaft or housing bore have a tight fit, the application of a special set of drums at the same time to install the bearing pressure to the shaft or bearing housing.
Separate type of bearings installed as inner and outer rings, respectively, can be easily mounted to the shaft or bearing housing. That should be noted at this time is to be installed to the inner shaft has been installed into the outer ring of the bearing box, try to keep it concentric to prevent abrasions rolling elements and raceways.
When the bearing of a larger size, due to the larger force required for installation, or heavy duty work and thus bearing a greater interference with the use of cold problems during installation, you need to pre-heat the bearing after the bearing inner ring or the installation. Installed in the hot, the heating temperature should be strictly controlled. Heating the bearings, the maximum heating temperature should not exceed 1200C, should normally be 80 ~ 1000C. With a dust cover or seal the bearing can not be heated, otherwise it will result in the loss of lubricant. Induction heating can be wives, and oil bath heating method.
