Overview
The Thomson SSUPB08 is a Super Smart ball bushing bearing pillow block engineered for demanding linear motion applications. This bearing is designed as a pillow block, 0.500 in open-type, self-aligning, adjustable, with integral double-acting seals. It provides smooth, quiet, low drag linear movement at 6x the load capacity or 216 x the L10 travel life of a conventional steel linear ball bushing bearing.
Key Features
- Universally self-aligning bearing offering twice the load capacity or eight times the travel life of the Super Ball Bushing
- Unique steel band design preserves ID fit-up and self-aligning capability; universal self-alignment optimizes load distribution between ball tracks
- 2 in OD, 0.687 in center line to base, dimensions 2 in L x 1-1/2 in W x 1.13 in H
- Low coefficient of friction reduces motor and drive requirements
- Double-lip integral wipers keep out dirt while retaining lubrication; steady state travel speeds up to 10 ft/s with accelerations to 450 ft/s
- Adjustable pillow block configuration for precision alignment in linear motion systems
