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 enables secure and straightforward mounting to equipment and transport systems. The housing is constructed from heavy steel sheet, providing exceptional durability and structural integrity to withstand rigorous operational environments. The wheel assembly incorporates a 3.94 inch diameter polyamide wheel body with an identical tread material composition, ensuring uniform wear characteristics and predictable rolling performance. The wheel is supported by a plain bearing system that facilitates smooth rotation while maintaining the fixed directional orientation characteristic of this caster type. The overall height of the caster assembly measures 5.04 inches, accommodating standard equipment configurations and clearance requirements. The caster demonstrates impressive load-bearing capabilities with a static load capacity of 881.85 pounds, enabling it to support substantial stationary loads without deformation or failure. Under dynamic conditions at speeds up to 2.49 miles per hour, the caster maintains a dynamic load capacity of 440.92 pounds, ensuring safe operation during transport and material handling activities. The Alpha caster is engineered for versatile applications including 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.
