Double-row ball, self aligningSuitable for radial and thrust loads. Useful where it is not possible to ensure accurate alignment of shafts or if shaft deflection is significant.

Bearing Types and Characteristics
Single-row deep groove ballPrimarily intended for radial loads but will tolerate some axial load Locates axially in both directions. Suitable for high speeds.
.
Single-row cylindrical rollerGreater radial load capacity than ball bearing of same dimensions but susceptble to vibration damage. Some axial load can be accommodated provided that inner and outer rings have at least one flange each The inner ring shown has no flanges so no axial load can be accomodated.
.
Single-row needle rollerRollers have high length/diameter ratio otherwise similar to cylindrical roller type. Useful where radial space is limited. Suitable for very high speeds.
Single-row tapered rollerSuitable for radial or thrust loads or a combination. High load capacity. Must be fully located and used as a loaded pair for satisfactory performance.
Double-row ball, self aligningSuitable for radial and thrust loads. Useful where it is not possible to ensure accurate alignment of shafts or if shaft deflection is significant.
.
Spherical roller, self aligningSuitable for heavier radial and axial loads than the double row self-aligning type.
.
.
Single-row ball, angular contact Provides greater un-directional thrust capacity than the single deep ball bearing. Must be located axially and used as a loaded pair.
.
Single-row ball, thrust ball Suitable for heavy uni-directional axial loads at low speeds. For dual direction loads a double direction thrust ball bearing (or a pair of single-row) is required. Not suitable for radial loads.
