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.

Frequently Asked Questions

What is Duratek rubber (PPR)? ›
Duratek is a premium rubber compound (designated PPR) engineered for heavy-duty caster applications. It delivers smoother rolling, lower noise, and better floor protection than standard rubber. Handles the highest loads in the S34 stainless series.
Duratek vs. TPR vs. RN on the S34? ›
Duratek (PPR): premium option for heaviest loads and smoothest roll. TPR: value choice for lighter loads and noise-sensitive areas. Rubber on Nylon (RN): specialist choice for chemical-resistant environments. All on the same S34 stainless frame.
What load capacity does S34 Duratek handle? ›
Up to 1,000 lb per caster — the highest in the S34 series. A set of four supports up to 4,000 lb total.
