This Hamilton FMK 6"x3" Metal Rigid Caster – 2000 lb is rated to 2000 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 Cast Iron wheel with a 3" 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 with a 4-1/2" x 6-1/2" 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 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 Up 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 Cast Iron 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 7.5". Account for it when checking equipment clearance, dock height, and ergonomic working height.
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).
