When searching for a reliable and durable solution to your caster needs, consider Service Caster's 316 stainless steel solid polyurethane wheel casters. Built with 316 stainless steel, which contains additional molybdenum and nickel content, makes this caster more corrosion resistant than standard 304 stainless steel. Molded as one solid piece, the non-marking, non-marring polyurethane wheel is free from debonding, and will not flatspot, as can occur with comparable polyurethane wheels, ensuring a smooth and solid roll over long periods of time. Mounting options include top plate, bolt hole, expanding stem and standard and metric threaded stem sizes. These versatile casters are ideal for a wide range of applications, such as dollies, platform trucks, warehouse carts and freight terminals. Or ensure a secure ride for food service carts, hotel housekeeping carts, and industrial and commercial equipment.
