This Hamilton 4" x 1 1/4" Poly-Tech Wheel – 300 lb is rated to 300 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". Verify your axle diameter and hub/bore length against your existing wheel before ordering.
Yes. Most wheels can be paired with a swivel or rigid rig to build a complete caster. Tell us your mount and load and we will spec the rig - request it on our bulk pricing page.
Rated for -20°F to 180°F. Operating outside the rated range can shorten wheel life and reduce capacity.
We accept purchase orders and offer Net 30 on approved accounts, ACH, and all major cards, plus tax-exempt ordering with a resale or exemption certificate. Volume discounts apply automatically; request a bulk quote for large or recurring orders.
