The Alpha is a fixed caster designed for stationary applications requiring reliable load support and directional 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 material and incorporates two ball races in the swivel bearing assembly, ensuring smooth operational performance and extended service life. The wheel measures 6.3 inches in diameter and is equipped with a roller bearing for reduced friction and consistent rotation. The wheel tread is manufactured from solid rubber in black with electric-conductive properties, providing enhanced safety in environments where static electricity dissipation is critical. The overall height of the caster assembly is 7.87 inches, accommodating standard equipment configurations. The Alpha caster supports a static load capacity of 595.25 pounds and a dynamic load capacity of 297.62 pounds at speeds up to 2.49 miles per hour. This fixed caster is engineered for diverse industrial applications including 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. The combination of robust construction materials, precision bearings, and electric-conductive tread makes the Alpha caster suitable for demanding environments requiring both durability and static control.
