Richmond Swivel Stainless Steel Elite Castor with 100mm Grey Poly Tyred Wheel and Directional Lock (S4478D)

This 100mm swivel castor with directional lock is built for applications where hygiene and corrosion resistance matter, including medical equipment, laboratory benches and food service carts. The frame is manufactured from Grade304 stainless steel and uses a double ball race swivel head for smooth steering under load. A polyurethane tyred, nylon centred wheel helps roll quietly and protect floors, while still handling regular cleaning and wet areas such as cool rooms and commercial kitchens. The wheel runs on stainless steel ball bearings and can be hose cleaned as part of routine wash-down processes.

With a maximum load capacity of 100kg (recommended 80kg), this castor suits mobile gear that needs both manoeuvrability and straight-line tracking when required. The directional lock holds the swivel in a fixed direction while allowing the wheel to rotate, which helps keep trolleys running true in corridors, service areas and tight workspaces. It mounts via a 12mm bolt hole and has a 133mm overall height, a 27mm wheel width and a 90mm swivel radius, making it a practical replacement or upgrade where stainless construction and controlled movement are needed.
