Linear Ball Bushings - Linear/Rotating, single, with seals. Series ST-UU, ST-UUB.

Volume Discount

THK

Hardened shaft, recommended for use with outer diameter tolerance (k5, m5, n5 or p5).

[Features]
· [Extremely low friction coefficient] Enables rotation with extremely low friction coefficient (=0.0006 to 0.0012) due to point contacts between the balls and ball rolling surface, and the separation of the balls within the ball cage.
· [Compact-design] Since the cross-sectional profile is simply the combination of the thin-walled outer cylinder and the balls, the outer diameter of this bearing is small and it is suitable for lightweight and space-saving compact designs.
· [High accuracy and low price] The sliding parts can be manufactured at low cost and a high level of accuracy is obtained.
