All measurements indicate the wheel diameter by the tread width.
The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.
W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.
Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.

When it comes to industrial applications, the R-MD-FT15H Hamilton Maxi-Duty Rigid Caster stands out as a reliable choice for those in search of durability, efficiency, and high performance. Let’s dive deeper into its unparalleled features:
Hamilton has been a beacon of quality in the caster industry. With its commitment to engineering excellence, this Maxi-Duty Rigid Caster is no exception, promising users the trusted Hamilton legacy of resilience and performance.
The caster boasts a wheel diameter of 14 7/8-inch, meticulously crafted from Ductile Iron. This choice of material ensures an extended product lifespan, even under demanding industrial environments, offering an unbeatable combination of strength and durability.
A central feature of this caster is its 1 1/2-inch Straight Roller Bearing. This bearing design not only enhances its load-bearing capacity but significantly reduces friction, ensuring smooth movement across all surfaces. Moreover, its rigid caster structure guarantees fixed, straight movement, eliminating any unnecessary swivel and ensuring a consistent direction.
With its user-centric design, the R-MD-FT15H Hamilton Caster ensures a hassle-free installation process. It’s not just about movement; it’s about providing an experience that reduces the operational workload and enhances efficiency.
Recognizing the diverse challenges of industrial settings, this caster is designed to be corrosion-resistant. Whether exposed to moisture, chemicals, or other potential corrosives, its robust build promises a consistent performance.
This caster runs a Ductile Iron wheel with a 2-9/16" 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 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 -20°F to 800°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 Ductile Iron 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).
