In engineering, the most common type of bearing system used is rolling element bearings. May be shielded and sealed. Angular contact bearings Allow higher axial loads than deep grove ball bearings, the axial loads may be of similar magnitude to the radial load. Matched pairs are available to allow for accurate shaft positioning axially. High load carrying capacity when axial load exceeds radial load.
Cylindrical roller bearings Large radial load but only a very light axial load carrying capacity.
Very high radial loads and a light axial load carrying capacity. Operates at a lower speed than cylindrical roller bearings and can tolerate some shaft misalignment. Tapered roller bearings Supports very large radial and axial loads but has a lower operating speed than angular contact bearing. Provides a very rigid shaft support. Needle roller bearings Similar to cylindrical roller bearings but has a very small bearing outer diameter.
