The RWM Casters SN2 hand truck wheel has an 8" diameter and a 2" width, 5/8" axle hole diameter, 440 lb. capacity, tire made of solid rubber to resist punctures and does not go flat, and a hub made of white polypropylene for strength. It is used as a replacement wheel for many hand trucks with 5/8" axles. The hub is off-set to provide greater clearance between the wheel and the hand truck compared to center-mount hubs. The wheel has a ball bearing to help reduce friction and support the load.
RWM Casters manufactures casters, wheels, and material handling products for automotive assembly, aerospace, and industrial applications. The company, founded in 1988 and headquartered in Gastonia, NC, meets International Organization for Standardization (ISO) standard 9001.
