SBR…LUU Open Double-Length Blocks
Long open blocks with two bushings for rail-mounted gantries under offset load.
SBR16LUU – SBR50LUUOverview
SBR…LUU open blocks extend the SBR body to carry two bushings, increasing load and moment capacity on supported-rail axes. They keep the open underside and end wipers, so they remain easy to mount and clean on router and plasma tables.
Key Features
- Two bushings for moment stiffness
- Open underside for supported rails
- Wiper seals on both ends
- Same rail interface as SBR…UU
