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.




















The Hamilton Series P Plastex Phenolic wheels are designed for heavy-duty performance. Molded under high pressure, these fiber-filled phenolic resin wheels are ideal for carrying substantial loads without damaging floors, even in intermittent service.
These non-marking wheels resist corrosion caused by oil, water, grease, and common acids or solvents, making them a reliable choice for challenging environments. Their design ensures no sparking, enhancing safety in various applications.
Engineered to withstand a wide temperature range from -50° to 260° F (continuously) and up to 300° F (intermittently), these wheels adapt to diverse operational conditions. They feature standard roller bearings, with options for straight or precision tapered roller bearings in larger sizes.
The Series P wheels ensure an anti-slip installation. The bearing cups are press-fit into counterbored ends for a secure fit. Most wheel sizes 5" and above (except for specific dimensions) come with ball-check pressure lubrication fittings for maintenance ease.
