Description
The Stainless Steel Model 3 swivel caster from Caster City is specifically designed for environments that destroy standard zinc-plated hardware. Constructed from 304 stainless stamped steel and buffed to a reflective finish, this caster arrives with a double ball bearing swivel section featuring stainless raceways, high-temp seals rated -20°F to 450°F, a grease fitting, and a dust cover—all included. The swivel assembly is secured by a 1/2″ diameter rivet with a 3/8″ diameter axle. The 2-3/8″ x 3-5/8″ plate offers bolt holes at 1-3/4″ x 3″, slotted to 1-3/4″ x 2-7/8″, using 5/16″ mounting bolts. Load rated to 350 lbs per caster. NSF listed and RoHS compliant for salt spray environments, coastal facilities, and chemical storage areas.
The welded disc polyurethane caster wheel features a liquid cast polyurethane tire chemically bonded to a welded steel disc center. This construction method provides a permanent bond between tire and hub that will not separate under heavy loads or impact. The polyurethane tire is non-marking and protects finished floors while offering excellent abrasion resistance and chemical resistance. The 65D Shore durometer provides quiet operation with high load capacity. This wheel is equipped with sealed precision ball bearings for smooth rolling performance. Polyurethane caster wheels roll easier on smooth floors than rubber wheels while supporting heavier loads. Not recommended for standing loads over extended periods. Ideal for food processing equipment, pharmaceutical carts, and institutional applications requiring quiet, floor-protective rolling in stainless steel caster configurations.
