How to install TIMKEN cylindrical bore bearings

For the installation of TIMKEN separable bearings, the inner ring and outer ring can be easily installed on the shaft or bearing seat respectively. At this time, it should be noted that the shaft with the inner ring installed is inserted into the bearing housing with the outer ring installed. When , try to keep it concentric to prevent the rolling elements and raceways from being scratched. When installing a non-separable bearing with a tight fit between the inner ring and the shaft of the TIMKEN bearing and a loose fit in the housing hole of the outer ring, the installation of the separable bearing can be easily installed on the shaft or the bearing seat separately because the inner ring and the outer ring are installed. Above. At this time, it should be noted that when inserting the shaft with the inner ring installed into the bearing housing with the outer ring installed, try to keep it concentric to prevent the rolling elements and raceways from being scratched. When installing a non-separable bearing with a tight fit between the inner ring and the shaft of the TIMKEN imported bearing and a loose fit in the outer ring bearing seat hole, the bearing can be installed on the shaft by a press first, and then the shaft together with the bearing is installed on the bearing. In the seat hole, if the bearing is small, a soft metal hammer can also be used to tap the end face of the ring to force the bearing, but the tapping force must be evenly distributed on the bearing ring. When the outer ring of the bearing and the bearing seat hole are tightly fitted, and the inner ring and the shaft are loosely fitted, the bearing can be installed on the shaft first. When the TIMKEN bearing ring is a tight fit with the shaft or the bearing seat hole, a special mounting sleeve is used to press the bearing onto the shaft or bearing seat at the same time. When the TIMKEN bearing size is larger, the required mounting force is higher When it is difficult to install in a cold state, the bearing inner ring or bearing seat needs to be heated in advance before installation. During hot installation, the heating temperature should be strictly controlled. When heating the bearing, the maximum heating temperature should not exceed 1200C, generally 80~1000C. Bearings with dust caps or seals must not be heated, otherwise the lubricant will be lost. The heating method can use electric induction beauty, oil bath heating and other methods.
