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.

Phenolic casters here serve bake carts, metalworking fixtures, and debris-heavy floors. Expect wheel diameters 8 in, phenolic treads, and plate-mount frames. Bring plate and stem measurements when replacing unmarked casters so the new corners sit level. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. These heavy-duty options cover everyday bake carts, metalworking fixtures, and debris-heavy floors without jumping to extreme forged series.
