Paired with ductile iron wheels, they feature many of the same characteristics of cast iron however, ductile iron has higher tensile and yield strengths. Its greater strength and flexibility — and less brittle-like cast iron tendency — help ductile iron become a better alternative in shocking applications. Packed with our straight roller bearings, which are most effective for heavy loads, and are a great option when facing excessive thrust loading, these casters are rated for 18000 lbs.
