Hamilton 20" Dual-Wheel Rigid Caster | 22,000 lb Capacity

This Hamilton R-UMD2-2090POY 20" x 9" Poly Rigid Dual Wheel Caster – 22000 lb is rated to 22000 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.

This caster runs a Polyurethane wheel with a 9" tread width. Polyurethane protects finished floors, rolls quietly, and resists most chemicals while carrying heavy loads.

This caster uses a top-plate mount with a 14" x 14" plate and a 12" x 12" bolt pattern. 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 Rigid caster. Rigid casters track straight for directional stability. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.

Rated for -30°F to 150°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 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.

The overall height (floor to top of plate or stem) is 25-5/8". Account for it when checking equipment clearance, dock height, and ergonomic working height.
