YZXQ :: Box Sliders (Aluminum)
SBR…UU Open Block Sliders
Open aluminum blocks that ride on supported shafts and clear the rail.
SBR10UU – SBR50UUOverview
SBR…UU blocks are open on the underside so the block can pass over a shaft that is fixed to a support rail. A wiper and seal set keeps debris out of the ball circuit while the block travels the full rail length. Sizes run from 10 mm to 50 mm shafts and pair with SBR rails.
Key Features
- Open underside for rail mounting
- Wiper seals on both ends
- Bolt-on top-face mounting
- Matches SBR support rails
