The Alpha is a fixed caster designed for demanding industrial applications requiring reliable mobility and stability. The caster features a rectangular plate fitting that enables secure mounting to equipment and transport systems. The housing is constructed from heavy steel sheet and incorporates two ball races in the swivel bearing assembly, ensuring smooth rotational movement and extended operational life. The wheel measures 3.94 inches in diameter and is equipped with a roller bearing for optimal load distribution and reduced friction during operation. The wheel tread is manufactured from solid rubber with non-marking properties, protecting floor surfaces while providing excellent grip and durability. The wheel body is composed of polypropylene, offering a lightweight yet robust construction that resists corrosion and chemical degradation. The overall height of the caster assembly is 5.04 inches, accommodating standard equipment configurations and clearance requirements. The caster supports a static load capacity of 330.69 pounds, making it suitable for stationary applications and permanent installations. Under dynamic conditions at speeds up to 2.49 miles per hour, the caster maintains a dynamic load capacity of 165.35 pounds, ensuring safe operation during transport and material handling. The Alpha caster is ideally suited for automotive original equipment manufacturing, catering carts and meal delivery systems, container construction, electronic systems and clean-room technology, fire fighting and fire protection equipment, machine construction, post logistic systems, production and platform trolleys, roll cages, tool cabinets, transport equipment, waste disposal equipment, and work benches.
