This 4″ (102 mm) Apex kingpinless ergonomic castor with extended lead is engineered for smooth, stable movement with enhanced tracking in industrial and commercial applications. With a load capacity of up to 317 kg per castor, it’s ideal for towable trolleys, carts and mobile equipment where controlled manoeuvrability and reliable load support are essential.
The ergonomic polyurethane wheel offers excellent shock absorption, low rolling resistance and gentle floor contact, helping to protect surfaces while delivering consistent performance. Its extended lead design improves directional stability and reduces wobble when towing or pushing over longer distances or uneven surfaces. A precision ball journal bearing ensures effortless swivel action and smooth rolling, while the castor operates effectively across a wide temperature range from −20 °C to +80 °C.
