Openbuilds Big V Slot Wheel Kit
Solid V Wheels are a strong wheel that resists deflection and distributes loads. It is usually used when heavier loads are required and will compress less than the Dual V Wheel. If many of these wheels are added to a gantry plate it will allow for an even distribution of the load.
The Solid V Wheel also has improved performance when used in conjunction with a Belt & Pinion system because it provides a flat surface for the belt to ride on.
