The Alpha is a fixed caster designed for stationary mounting applications requiring reliable load support and directional stability. The caster features a rectangular plate fitting that provides secure attachment to equipment and structures, while the housing is constructed from heavy steel sheet to ensure durability and resistance to demanding operational environments. The wheel assembly incorporates a 3.15 inch diameter polyamide body with a tread material identical to the wheel body, supported by a plain bearing that delivers smooth rotational performance and minimal maintenance requirements. The overall height of the caster measures 4.25 inches, providing appropriate ground clearance for most industrial applications. The load capacity specifications indicate a static load rating of 881.85 pounds, allowing for substantial weight support during stationary use, while the dynamic load capacity reaches 440.92 pounds at a maximum speed of 2.49 miles per hour, making this caster suitable for controlled movement applications. The Alpha caster is engineered for versatile use across numerous industrial sectors, including automotive original equipment manufacturing, catering carts and meal delivery systems, container construction, electronic systems and clean-room technology environments, 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, demonstrating its broad applicability in both light and medium-duty material handling and equipment mobility solutions.
