The Alpha stainless is a swivel castor with total lock, featuring a bolt hole fitting for secure installation on equipment and machinery. The housing is constructed from heavy-duty stainless steel and incorporates two ball races within the swivel bearing assembly, ensuring smooth rotational movement and reliable directional control. The wheel comprises a 125 mm diameter design with a polyamide body and injected polyurethane tread material, paired with a stainless steel roller bearing to deliver exceptional durability and corrosion resistance in demanding environments. The castor achieves an overall height of 155 mm, making it suitable for integration into compact and space-constrained applications. Load capacity specifications indicate a static load rating of 300 kg and a dynamic load rating of 150 kg at a maximum operational speed of 4 km/h, providing robust performance across varied industrial applications. The Alpha stainless is particularly well-suited for deployment in catering carts and meal delivery systems, container construction, electronic systems and clean-room technology, fire fighting technology and fire protection equipment, machine construction, and transport equipment, where corrosion resistance, reliability, and controlled manoeuvrability are essential operational requirements.
