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.

Crossed-Roller Bearings
With a considerably larger ID than our Face-Mount Crossed-Roller Bearings, use these to run 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.

High-Load Low-Friction Telescoping Slides
With a row of crossed-roller bearings on each side of the rail, these slides have over twice the load capacity of standard low-friction slides and are better for handling shock loads. Use them for short-travel, high-speed applications where low-friction performance is a must.
Travel length is the total distance the carriage travels in both directions. For example, a slide with a 6" travel length travels 3" in each direction.
Note: Capacities listed are for horizontal mounting. If side mounted, load capacities are cut in half.
