Precision Ball Bearings
For greater accuracy and higher speeds, these bearings are made to tighter tolerances than standard ball bearings.
Shielded bearings dissipate heat more efficiently than sealed bearings.
Sealed bearings block out dust and other contaminants better than shielded 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.

Combination Ball/Needle-Roller Bearings
A built-in thrust ball bearing reduces wear from adjacent shaft components, while the needle rollers support high radial loads. Install anywhere you would use separate bearings for radial and thrust loads.
