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 are 8-inch Duratek casters best for? ›
The heaviest warehouse shelving and industrial rack systems where you need maximum load capacity, obstacle clearance, and long tread life.
Are 8-inch Duratek casters easy to push? ›
Yes. The large diameter and ball bearings reduce rolling effort significantly, even at 500 lb per caster.
Can I mix Duratek with standard TPR casters? ›
While the stem sizes may be compatible, mixing wheel types can create uneven performance. We recommend using all Duratek for consistent tread life.
