8" x 3" Swivel Plate Caster with Ductile V-Groove Wheel

Made specifically for use on inverted angle iron track; although they can also be used on flat surfaces. Each wheel has a precisely machined 90° V-groove with a relief groove which enables load equalization.

Ductile steel is a composed of a combination of special alloys that give it higher weight capacities than cast iron; while being more economical than drop forged steel. Also referred to as malleable iron; material may flex rather than cracking or breaking when submitted to an extreme shock load. Features an extra thick walled, heavy-duty core, hub and tread face. Roller bearings are standard, with precision & tapered bearings as an option.

Excellent for heavy-duty guided industrial applications, assembly lines, paint lines, gates and where precise alignment is necessary.
