You're viewing caster wheel SKU W-6-V-5/8 on CasterConnection.com.
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.
. This wheel includes a Plain Bore with a caster hub length of 2-1/4".
