1. Standard type
2. Flanged outer ring
3. Extended inner ring
4. Expanded type in which one ring has a radial thickness that is larger than normal compared with the bearing width.
5. Thin section type in which both rings are extra thin in the radial direction. They can also be classified as: open, shielded, or sealed.
