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.

Match a 6-1/2 x 7-1/2 top plate when bolting casters under forging carts, aerospace fixtures, and multi-ton movers. Catalog chips cover wheel diameters 6, 8, 10 in, steel treads, and capacities 4,500 to 10,000 lb. Replace worn corners in matched sets when possible so the cart tracks straight under load. 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.
