Hamilton V-Groove Wheel 6 x 3 - 1-1/2" Roller Bearing

running v-groove 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.
