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.

Features & Benefits:

Two 2" or 3" non-marking gray soft rubber ball bearing wheels.

Soft rubber wheels provide a cushioned resilient ride protecting cargo as well as floor surfaces. It also reduces noise, vibration and rolls over small obstructions. Polyurethane wheels provide quiet rolling with a higher capacity.

The wider footprint provided by two wheels enables the casters to cross winch tracks, gaps and grooves in the floor.

Dual Wheel casters provide a higher load capacity with a minimum overall height.

The differential action provided by two wheels enables the caster to swivel easier than a single wheel having the same size footprint.

The Total Locking Brake locks both the swivel and the wheel simultaneously.

If these casters are going to be left parked for a prolong period there is the possibility that the tires could develop a flat spot. As a general rule, in situations like this reduce the rated capacity by 50% in order to minimize the possibility of a flat spot.
