Order the axle and spacers if the old ones are worn. Read the listing for the exact wheel size, overall height, and mount shown. Confirm the load rating printed on the title before you order. Measure the old wheel or caster before you buy. Polyolefin aisle: polyolefin casters. Caster hub: heavy duty casters.
