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.

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.

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.
