150mm Polyurethane On Nylon BB Richmond Wheel | PU6660-31

This 150mm polyurethane tyred nylon wheel is a practical choice for equipment that needs smooth rolling and predictable handling under load. With a 30mm tyre width and a 41mm boss width, it suits many general-purpose castor setups where stability matters and you want a tyre that helps protect floors compared to harder plastic wheels. The 150mm diameter also helps the wheel roll over joins, thresholds and minor surface changes with less effort, making it useful on trolleys, racks and mobile fixtures in busy work areas.

The wheel uses ball bearings for consistent movement and reduced rolling resistance during frequent starts, stops and direction changes. It has a maximum load capacity of 100kg with a recommended working load of 80kg for day-to-day use. The axle diameter is 5/16 inch (7.94mm), noting that some castor assemblies may use the same wheel with a different axle size depending on the bracket. This wheel is commonly fitted to several castor models, making it a handy replacement option when matching diameter, boss width and axle requirements.
