Alpha
3477HUR125P62

The Alpha is a swivel castor with total lock, designed for demanding industrial applications and equipped with a small rectangular plate fitting for secure mounting onto equipment and machinery. The housing is constructed from heavy steel sheet and incorporates two ball races within the swivel bearing assembly, ensuring smooth rotation and reliable directional control. The wheel features a 125 mm diameter and is mounted on a roller bearing, with a polyamide tread material that provides excellent wear resistance and durability across various floor surfaces. The wheel body is manufactured from a damping, hybrid material that effectively absorbs vibrations and reduces noise during operation, making it particularly suitable for sensitive environments. With an overall height of 155 mm, the castor offers a compact profile whilst maintaining substantial load-bearing capacity. The static load capacity reaches 400 kg, whilst the dynamic load capacity is rated at 200 kg when operating at speeds up to 4 km/h, making this castor suitable for both stationary and mobile applications. The Alpha castor is ideally suited for use in 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.
