Tapered-Roller Thrust Bearings
Thick, tapered rollers stand up to extremely high thrust loads.
Sealed bearings have better dust resistance than open bearings, but retain more heat.

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

Thin-Profile Crossed-Roller Bearings
For a more compact machine, these bearings have thinner inner and outer rings than high-load crossed-roller bearings. Route hydraulic lines, electrical wiring, and other components through the inside of the bearing. 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.
Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat.
