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.

Enhanced Precision Caster Series with Duralast Polyurethane Wheels

Duralast - the protective wheel that wears like steel - is liquid cast to a thickness of approximately 1/2" and chemically bonded onto heavy-duty iron wheel centers. The distinctive green treads are chemically inert, non-sparking, non-conductive, impervious to ozone, grease and most oils & solvents, and will not mark floors. Duralast Wheels are also guaranteed against tread separation for one year in ordinary free-wheeling applications (contact factory for excepted applications).
