With a coefficient of friction as low as 0.002, Thomson Super Ball Bushing bearings permit the use of smaller, less-expensive motors, belts, gears, and ball screws in place of high-friction plain bearings.
A self-aligning capability up to 0.5° automatically compensates for inaccuracies in base flatness or carriage machining. The bearings come in adjustable, closed, and open configurations and feature acceleration rates to 150 m/sec″; steady-state travel speeds to 3 m/sec without derating factors; double-lip integral wipers that keep contaminants out and retain lubrication; and lightweight, wear-resistant polymer retainers and outer sleeves that reduce inertia and noise. The bearings are available in metric sizes 16, 20, 25, 30, 40 and 50 mm.
