Thomson Super Ball Bushing® Bearings Now Available in Metric Sizes, Ready for Same and Next Day Delivery

Deliver higher performance from superior design when compared with standard bearing products

WOOD DALE, IL - Thomson Super Ball Bushing® bearings are now available in metric sizes 16, 20, 25, 30, 40 and 50mm. These precision bearings have a coefficient of friction as low as 0.001 that allows users to employ smaller and less expensive motors, belts, gears and ball screws when replacing high friction, plain bearings. Most Thomson Super Metric Ball Bushing bearings are available for same or next day delivery in North America and Europe. They are well suited for new applications, or as a drop-in replacement for existing applications, and are dimensionally interchangeable with competitive and legacy applications.

Thomson Super Metric Ball Bushing bearings have a self-aligning capability of up to 0.5º that automatically compensates for inaccuracies in base flatness or carriage machining. They deliver acceleration rates as high as 150 m/s² and steady state travel speeds up to 3 m/s without the derating factors commonly required with linear guides, and are available in adjustable, closed and open configurations. Double lip integral wipers keep contamination out and retain lubrication to maximize travel life. Lightweight, wear-resistant polymer retainers and outer sleeves reduce inertia and noise.

"When combined with our 60 CaseTM shafting, Thomson Super Ball Bushing bearings can be configured to last 27X longer or carry 3X the load of conventional bearings, allowing users to reduce component size while saving space and cost," says Dennis Howe, General Manager, Thomson Linear Bearings and Guides. "Thomson is the innovator of linear bearings and has supplied high quality products to the industry for more than 60 years. We believe that history of innovation and superior quality translates into better product reliability and performance, and users of our new metric Super Ball Bushing bearings will experience the difference," says Howe.
