Installation of the TIMKEN separation bearing inner and outer rings can be easily packed separately 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 boxtry to make it keeping concentric to prevent abrasion of the rolling element and raceway. TIMKEN bearing inner ring and shaft tight with non-separable type bearing outer ring of the bearing hole is loose with the installation,
      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.
      Tight fit on the TIMKEN imports bearing inner ring and the shaft, the outer bearing hole is loose with the non-separable type bearings installed can be used to press bearings will be installed on the shaft, then the axis together with the bearings packed together to the bearing Block holes, if bearing smaller, 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 bearing rings.
The 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.
TIMKEN 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 the bearing pressure to the shaft or bearing housing.
TIMKEN bearing a larger size, due to the required installation force, or under heavy-duty bearings with the surplus larger thus cold installation difficulties, you need to advance the bearing inner race or bearing 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.
