Self-Aligning Ball Bearings
With a spherical raceway and two rows of balls, these bearings compensate for shaft misalignment.
Open bearings dissipate heat more efficiently than sealed bearings.

High-Load Face-Mount Crossed-Roller Bearings
With thicker inner and outer raceways, these bearings can handle heavier loads than thin-profile crossed roller bearings. Mounting holes on the inner and outer rings allow for fastening onto hollow joints and shafts. The rollers face in alternating directions to allow for rigid, accurate motion under any combination of radial, thrust, and moment (twisting) loads. Use in applications where highly accurate motion is necessary, such as machine tools and industrial robots.
Open bearings dissipate heat more efficiently than sealed bearings.
Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat.

Spherical-Roller Bearings
Two rows of rollers give these bearings dynamic radial load capacities over five times higher than comparably sized tapered-roller bearings. Also known as rock crusher bearings, they handle heavy shock loads and are used for metal milling machinery, mining and oil field equipment, and in paper mills.
