Danaher offers the largest selection of sizes of Thomson self-aligning precision anti-friction linear bearings with load capacities up to 4,000 lbf, and speed up to 10 ft/sec (3 m/s). Additional features include:
-A self-aligning capability up to .5 degrees compensating for inaccuracies in base flatness or carriage machining. -The RoundRail* Advantage combined with the self-aligning feature, eliminating the need for derating factors commonly required for linear guides.
-Travel speeds up to 10 ft/s without a reduction in load capacity.
-Light weight, wear-resistant, engineered-polymer retainers and outer sleeves that reduce inertia and noise. -Radically floating bearing plates. When installed in an adjustable housing, the Super Ball Bushing bearing may be adjusted to a specific diametrical fit-up for accurate and repeatable movement.
-A constant coefficient of friction as low as .001.
-The use of smaller, less expensive drive motors, belts, linkages, gears and ball screws, when replacing high friction plain bearings.
-A closed configuration for end supported applications and an open configuration for continuously supported applications. -Ready to install pillow blocks with double acting seals and an access for lubrication. Installation and downtime is minimized
