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.

These 3-1/4 in Hamilton dual wheel casters fit shop carts, equipment, and material handling carts that move heavier loads. Casters in this collection range from 1,000 to 1,100 lb per caster. Wheels are 3-1/4 x 2 dual in swivel and rigid models. Dual wheel casters split the load over two wheels and swivel with less effort under heavy loads. Wheel options include polyurethane, nylon, phenolic, and forged steel, so match the tread to the floor and the load. Softer polyurethane or soft rubber or TPR tread is the better pick when the floor has chips or grit. Match the 4-1/2 x 6-1/2 in plate, bolt pattern, and overall height before you order. Choose swivel casters when the cart must turn in place and rigid casters for straight travel. Read the listing for the exact wheel size, overall height, and mount shown.
