Frequently Asked Questions

What is the load capacity of this caster?+

This Hamilton S-MD-84SWF70D 8" x 4" UltraGlide Swivel Caster – 5400 lb is rated to 5400 lbs per caster. Size a set by dividing the total load by the number of casters, and for uneven floors assume 3 of 4 casters carry the load. Keep continuous-use loads within about 75-80% of the rating.

What wheel does this caster use?+

This caster runs a Polyurethane wheel with a 4" tread width. Polyurethane protects finished floors, rolls quietly, and resists most chemicals while carrying heavy loads.

What plate size and bolt pattern does it use?+

This caster uses a top-plate mount with a 8-1/2" x 8-1/2" plate and a 7" x 7" bolt pattern. Measure your existing mounting holes before ordering; if you are replacing casters, match the bolt pattern - most standard patterns interchange across brands.

What floors and applications is it best for?+

The Polyurethane wheel performs best on smooth to semi-smooth floors including sealed concrete, tile, and epoxy. For non-marking or clean-environment needs, ask us about matching tread options.

What is the overall mounted height?+

The overall height (floor to top of plate or stem) is 11". Account for it when checking equipment clearance, dock height, and ergonomic working height.

How do I order, and what are the terms?+

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).
