Q: What is the difference between footstep bearing and thrust bearing?

Update Time:2020-04-07
A: Thrust bearings are also means footstep bearings

Thrust bearings are generally composed of two thrust washers or more thrust washers and several rolling elements. Generally, thrust washers are divided into shaft pieces and seat pieces. The most common type of rolling elements is made of iron or copper The quality cage is combined into a whole. The most common type of bearing is steel ball thrust bearing.

Thrust bearings are special bearings used to withstand axial forces, that is, bearings with forces in the direction parallel to the shaft.

working principle

Thrust ball bearing is a separate bearing. The shaft ring and seat ring can be separated from the cage and steel ball components. The shaft ring is a ring matched with the shaft, the seat ring is a ring matched with the bearing seat hole, and there is a gap between the shaft; the thrust ball bearing can only bear axial load,

One-way thrust ball bearings can only bear axial load in one direction,

Bidirectional thrust ball bearings can withstand axial loads in both directions;

Thrust ball bearings cannot limit the radial displacement of the shaft, the limit speed is very low,

One-way thrust ball bearings can limit the axial displacement of the shaft and the housing in one direction,

Bidirectional bearings can limit axial displacement in both directions.

Thrust roller bearings are used to withstand axial and radial combined loads, but the radial load must not exceed 55% of the axial load. Compared with other thrust roller bearings, this type of bearing has a lower friction factor, higher speed, and self-aligning performance.
