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 Bearing—Open bearings dissipate heat more efficiently than sealed bearings.

Sealed Bearing—Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat.

Thin-Profile Face-Mount Crossed-Roller Bearings

With thinner inner and outer rings, these bearings keep your machines more compact than high-load crossed-roller bearings. Route hydraulic lines, electrical wiring, and other components through the inside of the bearing. Mounting holes on the 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.
