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.

Needle-Roller Bearings
Also known as drawn-cup roller bearings, these are our thinnest roller bearings. The outer ring is drawn out to form a lip that holds the bearing together. Bearings take on the shape of their housing and may be oblong prior to installation.
Open bearings dissipate heat more efficiently than sealed bearings.
