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.

10" x 4" Forged Steel Casters

Plate sizes: 6-1/4 x 7-1/4Diameter: 6, 8, 10 inTread: 3, 4 inCapacity: up to 10,000 lb

Casters on the 6-1/4 x 7-1/4 plate pattern suit forging carts, aerospace fixtures, and multi-ton movers. Typical builds show wheel diameters 6, 8, 10 in, steel treads, and capacities 5,500 to 10,000 lb. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete. Larger plates spread bolt stress on thick frames under continuous tow abuse. These extreme-duty options cover everyday forging carts, aerospace fixtures, and multi-ton movers without jumping to extreme forged series.
