Richmond Castor Swivel with 100mm Polyurethane Tyred Wheel and Directional Lock (S4400D)

This heavy industrial swivel castor with directional lock is built for trolleys, equipment and mobile workstations that travel long distances across warehouses, logistics areas, manufacturing floors, display builds and exhibition sites. It uses a 100mm diameter wheel with a 50mm wide polyurethane tyre bonded to a cast iron centre to handle heavy loads while helping to reduce floor marking and vibration compared to all-metal wheels. With a 142mm overall castor height and 145mm swivel radius, it suits common baseplate mounting setups where reliable tracking and stable manoeuvring matter.

The directional lock lets you set the castor to run straight while the wheel still rotates, which helps keep long loads and multi-castor frames from drifting or fishtailing during pushes. Release the lock and the castor returns to full swivel for tight turns and positioning. A zinc plated finish supports corrosion resistance in day-to-day industrial use, while the 6mm thick baseplate and welded fork design are made to resist flex under load. A grease nipple supports routine maintenance to keep the swivel turning smoothly over time, and the roller bearing wheel helps with dependable rolling under working loads.
