Stainless steel casters have become the caster of choice for many harsh environments, including wash-down operations, high temperature applications, underwater environments, food processing plants, zoos and pharmaceutical factories. Hamilton offers three different series of stainless steel casters. The STL series is for light duty applications requiring capacities up to 325 lbs. per caster. For medium duty needs Hamilton offers the STA series—up to 800 lbs. per caster. And for rigorous or high-capacity requirements we offer the Stainless Workhorse made from forgings and rated up to 1,600 lbs. Each series provides a plethora of wheel selections in all the popular sizes. And you also have multiple bearing choices. Most models are stocked for same-day/next day PRONTO® delivery!
