The tight fit of the bearing inner ring and shaft outer bearing hole is loose with the non-separable type bearings installed can be used to press bearings will be installed on the shaft, and then the shaft together with the bearings packed together into the bearing hole if the bearing is small, can also be used relatively soft metal hammer tap the ferrule end face, forcing the bearing to the for the percussion force must be evenly distributed in the bearing rings.
The bearing outer ring and the bearing hole for a tight fit to the inner ring and the shaft is loose with the first load bearing days of the shaft.
Bearing ring and shaft or the bearing hole is a tight fit, the application of a special installation barrel while the bearing pressure to the shaft or bearing housing.
The installation of separation of bearings can be easily due to inner and outer rings were installed to the shaft or bearing housing should be given attention is already installed inner shaft insert has been installed good outer ring of the bearing box , try to keep it mind, to prevent abrasion of the rolling element and raceway.
When bearing foot grave, from the days required to install power, or to withstand the bearing of heavy-duty work with the interference larger and thus using the cold state installation difficulties, you need to advance the bearing inner race or bearing heating after the installation. The installation of the thermal state, the heating temperature should be strictly controlled. Heating 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 cause the lubricant loss. Heating can be electric induction wives, and oil bath heating.
