Stabilize your carriages against pitch, roll, and yaw forces by installing them in pairs.
Low-Friction Telescoping Slides
Use these slides for short-travel, high-speed applications where low-friction performance is a must. They have a bearing cage that eliminates ball collisions to extend service life.
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.
