125mm Polyurethane On Nylon RB Richmond Wheel | PU5508-37

This polyurethane tyred nylon wheel suits general-purpose trolleys, equipment and castor assemblies where you want a balance of load handling and floor protection. The 125mm diameter helps roll over joins and small debris more easily than smaller wheels, while the polyurethane tread reduces marking and softens vibration on hard floors. It’s built around a nylon centre for strength, and runs on ball bearings for smoother movement under load and improved service life in higher-use environments.

Designed for a 3/8in (9.53mm) axle, this wheel is commonly used as a replacement wheel on compatible castor frames where the boss width and axle size match. It has a 27mm tread width and 40mm boss width, with a maximum load rating of 350kg and a recommended working load of 300kg per wheel (allow for uneven floors and dynamic loads when moving). A practical option for workshops, back-of-house hospitality areas, stores, and facilities where reliable rolling performance and easy maintenance matter.
