SSUFB20

The Super Smart Ball Bushing® bearing family represents a major advancement in linear bearing technology worldwide. These patented and universally self-aligning bearings offer twice the load capacity or eight times the travel life of our industry standard Super Ball Bushing® bearing. To minimize installation time and cost, the Super Smart Ball Bushing® bearing can be ordered factory-installed in an industry standard single or twin pillow block.

Thomson® Super Smart Ball Bushing® Linear Bearing Flanged Pillow Block, Closed, Series: SSUFB, 1-1/4 in Shaft Dia, 3 in Outside Dia, 3-1/2 in Height, 3-1/2 in Length, 3.63 in Width, 2350 lb Dynamic, Steel Bearing, 185 deg F

• A precision, super finished, dual track bearing plate for optimum system smoothness and performance
• Longer travel life and minimal machine downtime when replacing conventional linear bearings or the industry standard Super Ball Bushing® bearing
• RoundRail™ advantage combined with universal self-alignment, eliminating the need for derating factors commonly required when using linear guides
• A coefficient of friction as low as 0.001 and allows the use of smaller, less expensive motors, belts, gears and ball screws when replacing high-friction, plain bearings
• Double-lip integral wipers that keep out dirt while retaining lubrication and travel life is maximized
• Steady state travel speeds up to 10 ft/s and accelerations to 450 ft/s without the use of derating factors
• Universal self-alignment
• The bearing plate is designed to rock 0.5 deg about the hardened precision ground outer ring
• The second key design feature of the Super Smart Ball Bushing® bearing plate is its ability to roll
• The shape formed by the rock and roll features allows the Super Smart Ball Bushing® bearing plate to rotate about its center
• The Super Smart Ball Bushing® bearing provides twice the load capacity of the industry standard Thomson® Super Ball Bushing® bearing and six times the load capacity of conventional linear bearings
• The Super Smart Ball Bushing® bearing provides eight times the travel life of the industry standard Thomson® Super Ball Bushing® bearing and 216 times the travel life of conventional linear bearings
