SKF bearing inner ring and shaft tight with the installation of the outer ring of the bearing hole is loose with non-separable type bearings can be used press bearings will be installed on the shaft, then the axis together with the bearings packed together to bearingholes, if bearing small, can also be used relatively soft metal hammer tap the ferrule end face forced bearings to as percussion force must be evenly distributed in the sleeve ring.
SKF bearing outer ring and the bearing hole for a tight fit, the bearing inner ring and the shaft is loose with the first installed in the shaft. SKF bearing rings and the shaft or the bearing hole is a tight fit, the application of a special installation sets of barrels at the same time bearing pressure to the shaft or bearing housing.
Separation of bearings in SKF installation can easily be 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 the outer ring of the bearing housing try to make it keeping concentric to prevent abrasion of the rolling element and raceway.
Required installation force, or under heavy-duty bearings with SKF bearing larger surplus larger and thus the cold state installation difficulties, you need to advance the bearing inner race or bearing seat heating before 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.
