Thrust bearing characteristics and installation precautions

The thrust ball bearing is a separate type of bearing, and the shaft ring and the seat ring can be separated from the components of the cage and the steel ball. The shaft ring is a ferrule that cooperates with the shaft. The seat ring is a ferrule that cooperates with the bearing housing hole, and there is a gap between the shaft; the thrust ball bearing can only bear the axial load, and the one-way thrust ball bearing can only bear Axial load in one direction, two-way thrust ball bearings can withstand axial loads in two directions; thrust ball bearings can not limit the radial displacement of the shaft, the limit speed is very low, one-way thrust ball bearings can limit one of the shaft and the housing Axial displacement of the direction, the two-way bearing can limit the axial displacement in both directions.

Thrust roller bearings are used to support axial and radial combined loads with axial loads, but radial loads must not exceed 55% of axial loads. Compared with other thrust roller bearings, this type of bearing has a low coefficient of friction, high speed and self-aligning performance.

Understand the characteristics of the thrust bearing, and then introduce the precautions for the installation of the thrust bearing:

1. Distinguish the tight ring and loose ring of the bearing (according to the inner diameter of the bearing, the hole diameter difference is O.1~O.5mm).

2. Distinguish the static parts of the mechanism (ie, parts that do not move, mainly refers to the assembly).

3. In any case, the loose ring of the bearing should always rest on the end face of the stationary part.
