The Alpha is a fixed caster designed for demanding industrial applications requiring reliable directional control and stability. The caster features a rectangular plate fitting that enables straightforward installation onto equipment and machinery. The housing is constructed from heavy steel sheet, providing exceptional durability and resistance to impact and wear in challenging environments. The wheel assembly incorporates a 4.92 inch diameter wheel with a thermoplastic rubber tread bonded to a polypropylene body, delivering excellent grip, chemical resistance, and longevity across diverse operational conditions. The roller bearing ensures smooth, consistent rotation while minimizing friction and maintenance requirements. The overall height of the caster measures 6.1 inches, accommodating standard equipment configurations and clearance requirements. The Alpha supports a static load capacity of 440.92 pounds, making it suitable for stationary or slowly moving applications, while the dynamic load capacity reaches 220.46 pounds at speeds up to 2.49 miles per hour, ensuring safe operation during transport and material handling. This fixed caster is engineered for use across 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, where dependable performance and load-bearing capability are essential requirements.
