The Alpha is a fixed caster designed for demanding industrial applications requiring reliable directional stability and consistent performance. The caster features a rectangular plate fitting that provides secure mounting to equipment and transport systems. The housing is constructed from heavy steel sheet, ensuring robust structural integrity and durability under continuous operational stress. The wheel assembly incorporates a 4.25 inch diameter polypropylene body with an identical tread material composition, supported by a roller bearing that facilitates smooth rotation and extended service life. The overall height of the caster measures 5.2 inches, allowing for precise integration into equipment designs with specific clearance requirements. The caster delivers a static load capacity of 661.39 pounds, accommodating substantial weight distribution in stationary applications, while maintaining a dynamic load capacity of 330.69 pounds at speeds up to 2.49 miles per hour, suitable for mobile equipment and transport scenarios. The Alpha caster is engineered for versatile deployment across automotive original equipment manufacturing, catering carts and meal delivery systems, container construction, electronic systems and clean-room technology, fire fighting technology 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, making it an essential component for industrial material handling and equipment mobility solutions.
