The Thomson Stainless Steel MultiTrac Ball Bushing bearings are constructed of 440 stainless steel components to resist rust and corrosion and operate in temperatures up to 180‚Â° F (82‚Â° C). The multiple track design delivers up to twice the load carrying capacity, or eight times the operating life, of conventional linear bearings. When combined with Thomson stainless steel 60 Case shafting the shaft life is also extended.
The Coefficient of Friction, which is as low as 0.001, lets you use small, less expensive motors, belts, gears and ball screws when replacing high friction, plain bearings. Travel speeds go to 10 ft/s (3 m/s) and accelerations to 450 ft/s2 (150 m/s2), without derating.
The bearings are available in 8, 12, 16, 20, 25, and 30 mm sizes as standard, with adjustable, closed and open configurations.
