The Alpha is a fixed castor designed for demanding industrial applications requiring reliable manoeuvrability and robust construction. It features a small rectangular plate fitting that enables straightforward installation onto equipment and transport systems. The housing is manufactured from heavy steel sheet and incorporates two ball races within the swivel bearing assembly, ensuring smooth rotational movement and extended operational longevity. The wheel comprises a 100 mm diameter design with a roller bearing that facilitates efficient load distribution and reduced friction during operation. The tread is constructed from solid rubber with non-marking properties, making it suitable for environments where floor protection is essential, whilst the wheel body is manufactured from polypropylene to provide durability and chemical resistance. The castor achieves an overall height of 128 mm, which must be considered during equipment design and integration. Load capacity specifications indicate a static load rating of 150 kg per castor, whilst the dynamic load capacity reaches 75 kg when operating at speeds up to 4 km/h. The Alpha castor is ideally suited for automotive original equipment manufacturer applications, catering carts and meal delivery systems, container construction, electronic systems and clean-room technology environments, 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. This comprehensive range of applications demonstrates the versatility and reliability inherent in the Alpha fixed castor design.
