V-groove caster wheel with a 90 degree groove are designed to guide heavy equipment roll on inverted angle iron track. The elevated track significantly reduces problems caused by floor debris. The relief groove equalizes the load on each face of the angle ensuring equal wearing. During the operation, parallel, straight and level should keep in case of casters running up over the track. Our v-groove casters are made of stainless steel, cast iron or other rigid material to minimize abrasion.
