This Hamilton 4" x 2" Poly-Tech Industrial Replacement Wheel – 500 lb is rated to 500 lbs per wheel. Divide the total load across the number of wheels in your rig and keep working loads within about 75-80% of the rating for continuous use.
This is a Polyolefin wheel. Polyurethane protects finished floors, rolls quietly, and resists most chemicals while carrying heavy loads.
4" diameter x 2" tread width. Verify your axle diameter and hub/bore length against your existing wheel before ordering.
