Every gearbox in our range is manufactured in our ISO 9001:2015 certified facility using CNC-machined spiral bevel gears from 20CrMnTi alloy steel, carburised to HRC 58-62. Multi-lip oil seals rated to IP65, premium tapered roller bearings, and heavy-duty cast iron housings ensure reliable performance in the harshest Australian field conditions — from outback dust to coastal moisture.
