Dalian journal bearing and thrust bearing

Rolling bearings are divided into two categories according to the main load direction:

Radial bearing

The radial bearing can bear the load perpendicular to the shaft. Some radial bearings can only bear pure radial load, while most radial bearings can also bear axial load in one direction. In some cases, they can also bear axial load in two directions

thrust bearing

The thrust bearing mainly bears the load along the axial direction. According to the design of pure axial thrust bearing, some bearings can bear additional axial load or combined load. The thrust bearing cannot reach the same high speed as the radial bearing of the same size.

The contact angle determines which category the bearing belongs to. Bearings with contact angle ≤ 45 ° are radial bearings and others are thrust bearings.
