Super Ball Bushings

The original self-aligning, precision, anti-friction linear bearing with load capacities up to 4,000 lbf (17,800 N), and speed up to 10 ft/sec (3 m/s). Available in closed, adjustable, and open styles, both single and twin versions in a large selection of sizes.

• A self-aligning capability up to .5 degrees compensating for inaccuracies in base flatness or carriage machining.
• The Round Rail 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 (3 m/s) without a reduction in load capacity.
• Light-weight, wear-resistant, engineered-polymer retainers and outer sleeves which reduce inertia and noise.
• Radially 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: minimal installation and downtime.
• Available from over 1800 distributors, worldwide.
