Is there a difference between bushings and bearings?

There is a difference between bearings and sleeves. The sleeve is actually just a type of sliding bearing. The main function of the bearing is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The shaft sleeve is a cylindrical mechanical part that is sleeved on the rotating shaft and is an integral part of the sliding bearing.

The sleeve is placed on the shaft to protect the shaft. After wear, the sleeve can be replaced to avoid direct wear of the shaft and reduce maintenance costs; the bearing is a rotating body that supports the shaft and can reduce friction.

The similarity between the shaft sleeve and the bearing is that both bear the load of the shaft. The difference is that the shaft sleeve has an integral structure, and when rotating, there is relative movement between the shaft and the shaft sleeve; while the bearing is split, and when rotating, The inner and outer rings of the bearing move relative to each other.

Bearings are an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

The shaft sleeve is a cylindrical mechanical part that is sleeved on the rotating shaft and is an integral part of the sliding bearing. Generally speaking, the sleeve and the bearing seat adopt an interference fit, while the shaft sleeve adopts a clearance fit.
