These are common SC8LUU nominal reference dimensions; dimensions and mounting details can vary by manufacturer or batch. Verify critical fit against the actual bearing before machining.

Selection and installation

The housing is fixed to a carriage or platform through its mounting points, while the shaft passes through the bearing. Check the mounting hole spacing, shaft centre height and clearance against your equipment before ordering; a matching shaft diameter alone does not confirm direct replacement compatibility. A long SC-LUU block requires more installation length and a different mounting pattern than its standard SC-UU counterpart.

Use a clean, straight shaft suitable for ball-type linear bearings. Align the shaft and bearing before tightening the mounting hardware, and check free movement by hand.
