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 S-52K-8SWC85 Swivel Caster sets the standard for robust and smooth mobility. This top-tier industrial caster combines superior design, materials, and precision engineering to offer unmatched performance and longevity.
The swivel caster is constructed with a bright zinc-plated finish, ensuring rust-resistance and durability. The aluminum core gives it a strong, sturdy base, while the distinctive blue tread provides additional robustness, allowing it to withstand heavy-duty use in industrial and commercial environments.
The S-52K-8SWC85 features an 8"x2" UltraGlide™ Ergo wheel that offers outstanding maneuverability. With its twin-wheel design and blue tread on aluminum center, the caster guarantees smooth movement even under high loads. The polyurethane tread is gentle on floors, reducing marks and scratches.
The caster is equipped with 3/4" sealed precision ball bearings for efficient operation. These bearings are maintenance-free, providing smooth and quiet rotation for the lifetime of the caster.
Designed for easy installation, the S-52K-8SWC85 swivel caster fits a 4" x 4 1/2" mounting plate with bolt holes measuring 2 5/8" x 3 5/8" and 3" x 3". The replacement wheel, W-820-SWC85-3/4, ensures convenient maintenance and long-term reliability.
This caster runs a Polyurethane wheel with a 2" 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).
