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

When do I need 6-inch Duratek casters? ›
Use 6-inch when rolling heavy shelving over rough warehouse floors, expansion joints, or dock transitions where smaller wheels would get stuck.
How long does Duratek rubber last? ›
Duratek outlasts standard TPR by 2-3x under similar loads. Exact lifespan depends on load, floor surface, and frequency of use.
Are these quiet on concrete? ›
Yes. Duratek rubber provides quieter rolling than hard plastic or steel wheels on concrete surfaces.
