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 installation onto equipment and machinery. The housing is constructed from heavy steel sheet, providing exceptional durability and resistance to wear, corrosion, and mechanical stress in challenging operational environments. The wheel assembly incorporates a 7.87 inch diameter polyamide body with an identical tread material composition, ensuring uniform wear characteristics and predictable rolling performance. The wheel is mounted on a roller bearing, which facilitates smooth rotation and minimizes friction during operation. The overall height of the caster measures 9.45 inches, accommodating various equipment configurations and clearance requirements. The caster demonstrates a static load capacity of 1543.23 pounds, indicating its ability to support substantial stationary loads without deformation or failure. Under dynamic conditions at a speed of approximately 2.49 miles per hour, the caster maintains a dynamic load capacity of 771.62 pounds, ensuring safe and reliable performance during transport and material handling operations. 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, making it an ideal solution for diverse industrial and commercial environments.
