Hamilton 18" Dual-Wheel Swivel Caster | 40,000 lb Capacity

This Hamilton S-UMD2-185NYB 18" x 5" Nylast Swivel Dual Wheel Caster – 40000 lb is rated to 40000 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 Nylon wheel with a 5" tread width. Nylon resists chemicals and moisture and carries high loads, which suits washdown and wet environments.

This caster uses a top-plate mount with a 14" x 14" plate. 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 -30°F to 220°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 Nylon wheel performs best on smooth, hard industrial floors. For non-marking or clean-environment needs, ask us about matching tread options.

The overall height (floor to top of plate or stem) is 23-5/8". Account for it when checking equipment clearance, dock height, and ergonomic working height.
