Ruth's Sister internal power cable

This Ruth's Sister internal power cable is supplied as a set of two LM6UU linear bearings sized 6 by 12 by 19 mm. It is intended for builders assembling or maintaining 3D printers that use matching rods and linear rails.

Practical limits of the LM6UU bearing

The LM6UU bearing fits only shafts and rails with a 6 mm inner diameter and the stated 12 by 19 mm envelope. Projects that require a different bore, length or load rating cannot use these parts.

Questions about this item

Should I choose the 12 mm or 19 mm version for my linear shaft?

The 12 mm figure is the outer diameter and 19 mm is the length of each LM6UU bearing; both dimensions belong to the same part, so you do not select between them.

What does the 12 mm outer diameter mean when the bearing is mounted on a 6 mm shaft?

It matches the standard LM6UU housing bore, giving a precise fit for 6 mm linear rods in 3D printer motion systems.
