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 W 1 1 4 Tread 4 with polyolefin and polyurethane treads, made to replace worn wheels on carts, dollies, racks, and equipment. Wheels in this collection are rated 250 lb per wheel. Wheels in this category are 3 inches in diameter with a 1-1/4 in tread width.

Polyurethane (poly or urethane) treads are quiet, floor safe, and resist water and many chemicals. Common uses include food service, bakeries, hospitals, schools, laboratories, and material handling carts. Match the bore, hub length, diameter, and tread width before you order. Order the axle and spacers if the old ones are worn. Read the listing for the exact wheel size, overall height, and mount shown. Confirm the load rating printed on the title before you order.
