These bearings have angular raceways for combined thrust and radial loads—install them where precision tolerances are required for accuracy and high speeds. They’re often used in spindle applications. To handle thrust loads in both directions, they have a double-row construction. Pair them with cylindrical roller bearings to better handle radial loads. They have an open construction to dissipate heat efficiently.

Face-Mount 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.
