Classification and characteristics of rolling bearings

Sort by roll shape

Rolling bearings can be divided into ball bearings and roller bearings according to the shape of the rolling body. Ball bearings can be divided into deep groove ball bearings and centripetal thrust ball bearings according to the ring structure; Roller bearings according to the shape of roller can be divided into cylindrical roller bearings, tapered roller bearings, needle roller bearings, self-aligning roller bearings, etc.

Classified by direction of load

According to the direction of load, it can be divided into radial load bearing and axial load bearing thrust bearing.

Other types of classification

According to the number of rolling body columns, it can be divided into single row, double row, three row, four row and multi-row bearing; According to whether the inner ring or the outer ring can be separated, it can be divided into separated type bearings and non-separated type bearings. There are special purpose bearings such as railway rolling stock bearings, ball screw bearings, precision spindle bearings, etc.
