These polycarbonate V-wheels are precision machined to allow FarmBot to move in the X, Y, and Z directions smoothly and precisely. Each wheel comes pre-assembled with two stainless steel rubber-sealed ball bearings and one M5 precision shim.

Now pre-assembled

As of the v1.4 hardware release, the V-wheels come pre-assembled. Please note that our bill of materials and pricing now reflect assembled V-wheels rather than individually listed components.
