Load Size Load size is often the determining factor in bearing size selection. Roller bearings have a greater load capacity than ball bearings with the same external dimensions. Generally, ball bearings are suitable for light or medium loads, and roller bearings are suitable for heavy loads.

For pure radial load, deep groove ball bearings and cylindrical roller bearings can be used. For pure axial load, thrust ball bearings and thrust cylindrical roller bearings can be used. When there are radial loads and axial loads (combined loads), angular contact ball bearings or tapered roller bearings are generally used. If the radial load is large and the axial load is small, the bearing person will be professional on WeChat! Deep groove ball bearings and cylindrical roller bearings with ribs on both the inner and outer rings can be selected. If there is also large deformation of the shaft or housing and poor installation alignment, spherical ball bearings or spherical roller bearings can be used. If the axial load is large and the radial load is small, thrust angular contact ball bearings can be used. If four-point contact ball bearings also require aligning performance, thrust spherical roller bearings can be used.
