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.
Engineered for OEM, MRO, and defense. Spec-match guarantee, engineering RFQ on every quote, fastest shipping in the caster industry.


The Durastar 35 SERIES casters feature robust 8-inch V-Groove Steel - VG wheels designed to provide superior performance across a variety of surfaces. These wheels ensure a quiet and non-marking operation, making them suitable for both indoor and outdoor applications.
Each caster is built to support up to 300 pounds, combining ease of movement with durable, reliable load-bearing capabilities. The zinc-plated finish not only adds to the visual appeal but also enhances the caster's resistance to rust and degradation.
Ideal for dynamic environments such as hospitals, schools, and industrial facilities, these casters offer an optimal balance of mobility and stability, ensuring your operations are efficient and uninterrupted.
Explore the functionality and advanced design of the Durastar 35 SERIES Casters. Equip your medium-heavy duty equipment with our reliable and smoothly operating casters to boost your productivity and workplace safety.
