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.

PRODUCT CODE: HQ2040R-PL1-SPR
Caster HQ's Blue Solid Polyurethane Elastomer wheel offers high weight capacities and great resistance to chemicals and wash-down applications. Our Blue Solid Poly Wheels are great for Steam Clean and full Wash-down applications while providing great floor protection and a quiet rolling operation. This wheel is great for clean rooms, labs, hospitals, and schools due to the non-marking high-quality polyurethane material. Optional precision ball bearings require less effort to start up and maintain a rolling load; they also generate less friction heat and may prolong the life of the wheel. Works well in both indoor and outdoor environments; however solid polyurethane wheels may flat spot if they are left with a maximum load for long periods; if this is an issue look at using aluminum, iron, or plastic core wheels.
