8 inch Polyurethane Heavy Duty Swivel Caster, 3 inch wide, USA Made

This made in USA heavy duty rigid 8" x 3" polyurethane on cast iron wheel caster offers high capacity, floor protection, and excellent durability–delivering better protection and quieter mobility versus steel wheels. The USA made rigid fork legs are constructed from high quality, heat-treated 3/8" thick AISI 1045 laser-cut steel and fully welded (inside and outside) to the notched yoke base (containing the precision machined raceway and 1/2" ball bearings), delivering superior strength and smooth swiveling. The kingpinless design eliminates kingpin failure, a leading cause of caster failure in heavier applications. The heavy duty, premium polyurethane (95 Shore A) wheel offers a 1/2" thick polyurethane tread, chemically bonded to a close tolerance cast iron core, providing trusted high-capacity and non-marking operation. The caster also features a leading 3-year warranty and RoHS compliant zinc plating with clear coat for superior corrosion resistance.
