The Hamilton Standard Duty Kingpinless Swivel Caster ensures smooth and efficient operation. Whether for commercial or industrial use, this caster stands up to demanding environments, carrying loads of up to 1400 lbs at 3 mph.
Hamilton is a recognized name in industrial tools, known for high-quality products. Our kingpinless swivel caster continues that legacy with its sturdy construction, precision-sealed ball bearings, and bright zinc plated finish.
This caster runs a Forged Steel wheel with a 2" tread width. Steel / iron wheels give maximum capacity and durability on smooth, hard industrial floors and tolerate heat.
This caster uses a top-plate mount. Measure your existing mounting holes before ordering; if you are replacing casters, match the bolt pattern - most standard patterns interchange across brands.
This is a Swivel caster. Swivel casters rotate 360 degrees for full maneuverability. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.
Rated for -22°F to 750°F. Operating outside the rated range can reduce wheel life and load capacity, so match it to your environment (wash-down, freezer, oven-adjacent, etc.).
The Forged Steel wheel performs best on smooth, hard industrial floors. For non-marking or clean-environment needs, ask us about matching tread options.
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. Stock items carry a 30-day return policy in unused condition (made-to-order items are non-returnable once production starts).
