Eccentric Spacer

These 6mm eccentric spacers are used with V wheels and Open Builds V-Slot (TM) aluminum extrusions to create simple, affordable linear motion systems. The spacer has an off-center 5mm bore, which allows you to tighten the wheel against the extrusion. The spacer sits in a 7.12mm hole and allows for an adjustment of up to 0.79mm. There is a divot on the spacer that indicates where the offset bore is closest to the edge.
