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.

This collection holds 12 in dia. Pneumatic Casters, built for shop carts, equipment, and material handling carts that move heavier loads. Casters in this collection are rated 2,100 lb per caster. The collection includes swivel and rigid models. Dual wheel casters split the load over two wheels and swivel with less effort under heavy loads. Air filled and flat free tires cushion the load and roll over gravel, grass, cracks, and debris. Match plate size, 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. Confirm the load rating printed on the title before you order. Measure the old wheel or caster before you buy. Check the floor type and the heaviest load the cart will carry before you choose. Pneumatic aisle: pneumatic casters. Wheel hub: replacement wheels.
