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.

The Hamilton R-AEZFFM-10SPRT is a pinnacle of engineering excellence, offering a fusion of a forged steel wheel core and wear-resistant Superlast Polyurethane tread. Its spring-loaded design ensures exceptional shock absorption, perfect for industrial and aerospace environments.
Boasting a platinum powder finish and a sleek black tire on a black rim, this rigid caster is not just a workhorse but also a piece of art. It combines aesthetics with functionality, offering corrosion resistance and visual appeal, ensuring it stands out in both performance and looks.
Designed to navigate with ease and precision, the R-AEZFFM-10SPRT is the preferred choice in aerospace, automotive, and manufacturing industries. Its weldment rig design and precision-sealed ball bearings offer smooth operation, even under heavy loads, affirming Hamilton's legacy of quality and performance.
This Hamilton R-AEZFFM-10SPRT 10" x 4" Solid Pneumatic Spring Loaded Rigid Caster – 1000 lb is rated to 1000 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 Rubber wheel with a 4" tread width. Rubber absorbs shock and protects floors, and runs quietly, which suits noise-sensitive and light-to-medium duty use.
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 180°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 Rubber wheel performs best on rough, uneven, or outdoor surfaces such as asphalt, gravel, and cracked concrete. For non-marking or clean-environment needs, ask us about matching tread options.
The overall height (floor to top of plate or stem) is 14". 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).
