This maintenance-free kingpinless castor with extended lead and 8″ donut wheel is designed for stable, effortless movement under heavy loads in demanding industrial environments. With a load capacity of up to 544 kg per castor, it’s ideal for towable trolleys, heavy equipment and mobile systems that require smooth tracking and reliable performance.
The large 203 mm ergonomic polyurethane donut wheel delivers exceptional shock absorption, low rolling resistance and enhanced floor protection — especially useful across rough surfaces, debris or uneven floors. Its performance remains dependable throughout a wide temperature range from –20 °C to +80 °C. The kingpinless design eliminates the traditional wear point of a swivel pivot, increasing strength and long-term durability, while a ball journal bearing ensures smooth rolling and easy directional control.
The extended lead geometry improves tracking and reduces swivel flutter when pushing or towing over longer distances, making this castor especially effective for industrial handling, logistics and transport tasks. A robust top plate fitting allows secure and straightforward installation on compatible equipment.
