For the heaviest-duty applications, the 330 Series features a thick, precision-machined grade 316 stainless swivel section and 304 stainless steel rig. Both are highly polished for aesthetic. Ideal for applications exposed to cleaning agents, wash-downs, caustic solutions, steam, marine environments, or any other corrosive agents which could cause rust.

All components, including the ball bearings in the kingpinless swivel section, are stainless. Kingpinless casters eliminate kingpin failure – the leading cause of caster failure. Kingpinless casters also increase a caster’s ergonomic abilities, making them more ideal to reduce employee strain.
