The Alpha is a fixed caster designed for demanding industrial applications requiring reliable mobility and stability. The caster features a rectangular plate fitting that enables secure mounting to various equipment and structures. The housing is constructed from heavy steel sheet and incorporates two ball races in the swivel bearing assembly, ensuring smooth rotational movement and extended operational life. The wheel measures 4.92 inches in diameter and is equipped with a roller bearing for optimal load distribution and reduced friction during operation. The wheel tread is manufactured from injected polyurethane, providing excellent grip, durability, and resistance to wear across diverse surfaces, while the wheel body is constructed from polyamide for lightweight strength. The overall height of the caster assembly is 6.34 inches, making it suitable for integration into compact and space-constrained applications. The Alpha caster delivers a static load capacity of 1,322.77 pounds, accommodating substantial weight requirements in stationary positions. Under dynamic conditions at speeds up to 2.49 miles per hour, the caster maintains a dynamic load capacity of 661.39 pounds, ensuring safe and reliable performance during movement. This versatile fixed caster is ideally suited for automotive OEM applications, 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.
