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.

3/4" x 1-3/16" Roller Bearings

Diameter: 1, 1-3/16, 2 in

3/4" x 1-3/16" Roller Bearings for warehouse carts, racks, and everyday plant fixtures. Expect wheel diameters 1, 1-3/16, 2 in and industrial frames. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. Size capacity from the heaviest corner load with shock margin, and keep overall height consistent across the set. These medium-duty options cover everyday warehouse carts, racks, and everyday plant fixtures without jumping to extreme forged series.
