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.




Polyolefin wheels are molded in one piece from hard, non-marking plastic that does not absorb water. Ours are 2 in wide and rated 500 to 900 lb.
One-piece molded polyolefin resists water, brine, oils, and common cleaners without a soft tread to swell or peel. It is light, non-marking, and priced for fleet replacement [S2][S3].

No. These are bare polyolefin wheels with no soft tread. Polyurethane-on-polyolefin adds a urethane face for quieter roll and floor protection.
500 to 900 lb per wheel across the four active sizes.
Yes for water and many chemicals. Hot-water temperature is the limit; confirm the listing field near 180°F.
Choose polyurethane for floor protection and quieter roll, nylon for higher heat or tougher chemical duty, or metal for chips and extreme heat.
