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.
















Hamilton's Ergo-Tech wheels, known for their superior rolling efficiency, are designed to minimize push/pull forces, reducing work-related injuries. The wheel features a unique half-round tread combined with maintenance-free precision ball bearings for effortless rolling.
The wheels are made with a high energy, softer 87A durometer polyurethane, ensuring greater traction, repelling debris, and quieter operation than most other urethanes. This material choice contributes to both the durability and ergonomic benefits of the Ergo-Tech wheels.
Perfect for environments where ergonomic efficiency is crucial, the Ergo-Tech wheel is Hamilton's premier choice for reducing physical strain in the workplace. For those requiring a balance between push/pull effort and durability, consider our Ergo-Glide wheels.
