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 S-ZFSEC-95POYB Hamilton Spinfinity Super Endurance Swivel Caster is a top-of-the-line industrial mobility solution. This high-end swivel caster is renowned for its superior endurance and unparalleled performance, primarily due to its Spinfinity design.
Featuring a 9" x 5" Red Polyurethane (85A) Presson Wheel, the caster is not only durable but also provides excellent ease of movement. Polyurethane wheels are known for their impressive load-bearing capacity and resistance to wear and tear, making this product ideal for heavy-duty applications.
The inclusion of 1 1/4" Sealed Precision Ball Bearings ensures smoother operation by significantly reducing friction. These bearings are sealed to prevent dust and other particles from impeding their function, thus enhancing their lifespan and reliability.
With an impressive load capacity, this caster is well-equipped to handle heavy-duty industrial applications. Whether you're moving heavy machinery or need reliable mobility for a loaded cart, this caster is up to the task.
The swivel technology incorporated into this caster offers a larger contact area and better weight distribution. This results in improved turning performance, even under heavy loads.
The kingpinless design of this caster's rig type ensures improved shock absorption, reducing wear and extending the caster's service life. With this feature, the caster is well-suited to withstand the demands of rigorous industrial use.
This caster runs a Polyurethane wheel with a 5" tread width. Polyurethane protects finished floors, rolls quietly, and resists most chemicals while carrying heavy loads.
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 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 -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 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.
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).
