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.




















Introducing the new UltraGlide Ergo - Hamilton's advanced modular wheel design engineered to significantly reduce the energy needed in both manual and powered applications. This latest innovation features independent swivel surfaces to eliminate scrubbing, facilitating easier turning.
With split outer raceways, the UltraGlide Ergo minimizes friction, ensuring low startup and maintenance forces. The polyurethane tread, tailored for ergonomic applications, provides a softer 85A for quieter operation and improved debris resistance.
Crafted from high-grade liquid cast polyurethane with a hardness of 82-85 Durometer (Shore A), these wheels offer superior abrasion resistance, a broad temperature range (-50° to +175° F intermittently), and are not affected by occasional steam cleaning. The crown tread with a flat center band ensures smooth, easy rolling.
