YZXQ :: Box Sliders (Aluminum)
SCS…LUU Double-Length Box Slider Blocks
Double-length closed blocks carrying two LM bushings for higher load and stability.
SCS8LUU – SCS60LUUOverview
SCS…LUU blocks use the same housing profile as the SCS…UU series but twice the length, with two bushings supporting the shaft. The longer bearing span raises moment capacity and reduces rocking on cantilevered carriages, so the series suits router Z axes, gantries with offset loads and long-travel slides.
Key Features
- Two bushings per block
- Higher moment and load capacity
- Same mounting height as SCS…UU
- Sealed UU bushings fitted as standard
