Thomson® Super Ball Bushing® SPB12OPN Adjustable Open Linear Bearing Pillow Block, 3/4 in Dia Shaft, 0.937 in Center Line to Base, 2-3/4 in L x 1.88 in W x 1.56 in H
The Super Ball Bushing® bearing has been the industry standard for self-aligning linear bearings for over twenty years. This bearing provides three times the load capacity or 27 times the travel life of conventional linear bearings. Besides the dramatic increase in load capacity, the Super Ball Bushing® bearing is self-aligning, lightweight and adjustable with a low coefficient of friction. It is a quick and easy replacement for high friction plain bearings. The wear-resistant, engineered-polymer retainers and outer sleeves reduce inertia and noise in critical, high speed applications.

- A self-aligning capability up to 0.5 deg compensates for inaccuracies in base flatness or carriage machining
- 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
- Lightweight, wear-resistant, engineered polymer retainers and outer sleeves that 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 0.001
- The use of smaller, less expensive drive motors, belts, linkages, gears and ball screws, when replacing high friction plain bearings
- Greater ball to bearing plate contact provides the increase in three times load capacity or travel life
- Zero clearance fit
- Smooth, quiet operation
- Open pillow blocks are for continuous supported shafting
- For class L shafting
- Ball bushing bearings are included and factory installed in each pillow block

Thomson® Precision Steel Ball Bushing® A61014 Closed Linear Bearing, 3/8 in Dia Shaft, 5/8 in OD, 7/8 in L
Precision Steel Ball Bushing® bearings offer great improvements in efficiency, productivity and accuracy over high-friction plain bearings flat-ways. The all-steel design makes the bearing product line perfect for replacing plain bearings in high temperature applications. Rigid construction makes them very durable compared to ball bushing bearings with polymer components. When installed in a standard Thomson® pillow block, the Precision Steel Ball Bushing® bearing can self-align up to 3 deg in all directions.
