SKF bearing inner ring and the shaft is a tight fit, the outer ring of the bearing hole is non-separable type bearings to install a more loose fit, available presses the bearing be installed on the shaft, then the shaft together with the bearing onto the bearing seathole, if the bearing is small, but also can be a relatively soft metal hammer the putter ferrule end face to force the bearing to as, but striking force must be evenly distributed on the sleeve ring.
SKF bearing outer ring and bearing holes for a tight fit, the inner ring and the shaft than loose fitting, bearing mounted on the shaft. When SKF bearing rings and the shaft or bearing holes are a tight fit, the application of a special installation sets of barrels at the same time bearing pressure to the shaft or bearing housing.
Separated type bearings in SKF install the inner and outer rings were fitted to the shaft or bearing housing, should attract the attention of the already installed the inner ring of the shaft will insert mounted the good outer ring of the Order of the box , try to keep it concentric prevent abrasions rolling element and raceway.
SKF bearing size is larger, due to the required installation of a larger force, or under heavy load bearing with the interference thus adopting Cold problems during installation, you will need to pre-heating of bearing inner ring or bearing prior to installation.
The installation of the hot, the heating temperature should be strictly controlled. Heating bearings, maximum heating temperature shall not exceed 1200C, should generally be in the 80 to 1000C. Bearing with shields or seals can not be heated, otherwise it will cause lubricant loss. Heating can be electric induction wives, and oil bath heating method.
