Running V-Grooved Wheels on inverted angle iron track is a popular and low-cost method of taking loads off the floor and creating production-line flow. A relief groove in the "V" assures proper weight distribution and makes wheel and track "self-cleaning," while a partial flat-tread permits rolling the wheels directly on floors as well.

All cast iron and forged steel models are offered with plain bore or straight roller bearings while some models also offer precision tapered roller bearings for optimum capacity and performance.

However, proper adjustment of tapered bearings precludes side-to-side wheel play.

To avoid the necessity for perfectly parallel tracks, directional control can be achieved by using a single track on one side only, and running flat-tread wheels of matching height on the opposite side.
