www.danahermotion.com 15 Thomson RoundRail Linear Guides and Components . . .The RoundRail Advantage - The inherent ability of a RoundRail Ball Bushing bearing system to accommodate torsional misalignment (caused by inaccuracies in carriage or base machining or by machine deflection) with little increase in stress to the bearing components. Super Ball Bushing Bearing Pillow Blocks Available in closed, adjustable and open styles in both single and twin versions. Thomson Super Ball Bushing Bearings are also available factory installed in single or twin pillow blocks. Super Ball Bushing bearing pillow blocks are provided with integral, double acting seals that keep out contaminants and retain lubrication, maximizing system performance and life. Twin versions provide up to twice the load capacity or eight times the life of single versions, allowing the use of smaller and less expensive drives, motors and ball screws. When replacing v-ways and flat-ways, the Super Pillow Block’s low coefficient of friction reduces power consumption and provides important design economies. In stock and available in sizes from 1/4 to 2 inch from over 1800 distributors worldwide. (See Page 52) Precision Steel Ball Bushing Bearing Products Rigid, Precision Steel Ball Bushing Bearing design eliminates binding and chatter found in high friction plain Bearings. Precision Steel Ball Bushing Bearings are available in an open version for continuously supported applications and a closed version for end supported applications. Extra precision and adjustable versions are available for end supported applications requiring higher precision and repeatability. Precision Steel Ball Bushing bearing products are also available factory installed in a self-aligning, malleable iron pillow block minimizing installation time and cost. The all-steel design makes the Precision Steel Ball Bushing bearing product line perfect for replacing plain Bearings in high temperature applications. Available in 72 sizes and configurations from over 1800 distributors worldwide. Now available in 440 stainless steel, ideal for harsh and high temperature environments. (See Page 66) Miniature Instrument Ball Bushing Bearings High Accuracy and Compactness for Instrumentation Level Applications. The accuracy level and compact size make the Instrument Ball Bushing bearing ideal for small mechanisms or devices that require high repeatability and responsiveness. When replacing high friction plain Bearings, the Instrument Ball Bushing Bearings’ constant low coefficient of friction eliminates stick-slip and provides smooth linear performance. Each Instrument Ball Bushing bearing can be provided with a matched 60 Case LinearRace shafting for minimum fit-up, optimizing system performance and accuracy. In stock and available in sizes 1/8, 3/16 and 1/4 inch from over 1800 distributors, worldwide. (See Page 77) Ball Bushing Bearings Overview
