Semi-Steel Casters

Diameter: 4, 5, 6, 8 inTread: 2 inCapacity: up to 1,400 lb

Semi-Steel Casters for warehouse carts, racks, and everyday plant fixtures. Typical builds show wheel diameters 4, 5, 6, 8 in, cast iron and steel treads, and plate-mount frames. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. These medium-duty options cover everyday warehouse carts, racks, and everyday plant fixtures without jumping to extreme forged series.
