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.

22" dia. Rubber Wheels

Capacity: up to 22,800 lb

Rubber casters here serve finished floors and quiet institutional carts. Catalog chips cover rubber treads, industrial frames, and capacities 22,800 lb. Replace worn corners in matched sets when possible so the cart tracks straight under load. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races. These extreme-duty options cover everyday finished floors and quiet institutional carts without jumping to extreme forged series.
