The Alpha is a swivel caster with total lock designed for demanding industrial applications requiring reliable mobility and secure positioning. The caster features a rectangular plate fitting that enables straightforward installation onto equipment and transport systems. The housing is constructed from heavy steel sheet and incorporates two ball races in the swivel bearing assembly, ensuring smooth rotation and extended operational life. The wheel measures 4.92 inches in diameter and is manufactured from polypropylene, with the tread material being identical to the wheel body for consistent wear characteristics and performance. The overall height of the caster is 6.1 inches, providing appropriate clearance for most industrial equipment configurations. The load capacity specifications indicate a static load rating of 881.85 pounds, allowing the caster to support substantial stationary loads, while the dynamic load capacity reaches 440.92 pounds when the caster is in motion at speeds up to 2.49 miles per hour. The roller bearing design ensures reliable performance across diverse 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. This comprehensive load capacity and robust construction make the Alpha caster suitable for heavy-duty industrial environments where durability and dependable locking functionality are essential requirements.
