How to install correctly the bearing thrust washer?

bearing thrust washer is an annular part of thrust rolling bearing with one or several raceways.

As we all know, the installation of bearings directly affects the operation of bearings. If the installation is not correct, the method is incorrect, not only can not achieve the expected effect of the bearing, but also affect the service life of the bearing. This article describes the correct installation position of the different shaft rings in the bearing. ​The intermediate ring is used between the two rows of rollers in the two rows of two-way thrust rolling bearings, and there are bearing thrust washer on both sides of the intermediate ring. The adjusting seat ring, because it has a seat ring on the back of the ball, is suitable for permanent angular displacement between the axis of the bearing and the axis of the valve seat.

The self-aligning seat bearing thrust washer is used for the bearing thrust washer between the self-aligning seat ring and the thrust bearing surface of the housing. Its surface is a concave spherical surface matching the spherical backrest of the self-aligning seat ring.

The main form of the bearing seal is to install a device with a sealing effect on both end faces of the rolling bearing. With the development of industry, bearing seals have gradually entered people's vision. It is a technology that has received much attention in recent years. Before the development of bearing seals, all bearings were open bearings. The seal ring structure of the bearing seal is different, and the sealing effect is also different. If there is a gap between the seal ring of the bearing seal and the rotating shaft, it is called a non-contact bearing seal. In this type of sealing, the smaller the gap, the better the sealing effect, but the smaller the gap, the lower the rotational speed of the rotating shaft.

The larger the gap, the worse the sealing effect, and the higher the rotation speed of the rotating shaft. There is no gap between the seal ring and the bearing seal shaft, called contact seal. The bearing seal uses a contact seal. The contact surface of the sealing lip and the rotating shaft determines the sealing effect. The larger the contact surface, the better the sealing effect. However, the lower the allowable speed of the rotating shaft, the smaller the contact sealing surface, the worse the sealing effect, but the higher the allowable speed of the rotating shaft.
