It is known that FreeRun Bearing is one of popular manufacturers and suppliers of V groove bearing in China. The most professional V groove bearing is stainless steel v groove wheels.

Running Stainless V-Grooved Wheels on inverted angle iron track is a popular and low-cost method of taking loads in corrosive environments off the floor and creating production-line flow. These wheels are made from Type 303 stainless steel. 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 stainless steel v-groove models are offered with plain bore, Delrin bearings, or stainless steel precision ball bearings for optimum capacity and performance.

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.
