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.

| Wheel | Listed ratings per caster | Listed temperature (most common) | Best use |
|---|---|---|---|
| Polyurethane (Duralast, Ultralast, UltraGlide and others) | 300 to 40,000 lb | -5 to 160°F or -50 to 200°F | Quiet, floor-friendly rolling with high capacity |
| Cast iron | 200 to 16,000 lb | -40 or -30 to 320°F | Hard, low rolling effort on smooth concrete |
| Forged and other steel | 560 to 36,800 lb | -40 to 320°F; high-heat versions to 750°F | Shock loads, heat, debris |
| Nylon (including Nylast) | 260 to 40,000 lb | -30 to 220°F | Heavy loads on smooth floors, chemicals |
| Phenolic (Plastex) | 450 to 10,000 lb | Up to 250°F | Low rolling effort, oil resistant |
| Rubber | 120 to 9,600 lb | -30 to 120 or 160°F | Cushion and quiet on rough or finished floors |
| Polyolefin (Aqualite) | 240 to 1,000 lb | -20 to 200°F | Washdown and wet areas |
Ranges from product fields on this page [S2]. Each family has its own rating and temperature, so check the listing.
In the titles here, S- marks a swivel caster and R- a rigid one, followed by the rig series and the wheel code, for example S-WH-6NYB or R-FM-83GB95 [S2]. If the old caster still carries its stamp, search that number first. If not, measure the plate, wheel diameter and tread width, and note the rig height.
Browse by type: heavy duty casters, polyurethane casters and metal wheels.
Hamilton Caster is based in Hamilton, Ohio, where it has built casters since 1907, and it manufactures in the USA.
Several dual wheel and large polyurethane and Nylast casters are listed at 40,000 lb per caster.
S marks a swivel caster and R a rigid caster. The letters after them name the rig series and wheel.
Polyurethane is quiet and kind to concrete. Cast iron and forged steel roll easier under very heavy loads but are loud and harder on the floor.
Lead time on Hamilton casters depends on the model: Hamilton builds many of them to order, typically 4 to 6 weeks, and the ones it stocks for Pronto Ship go out faster.
