Construction & Design

The Boundary Billet Oil Pump Gear is crafted from premium billet steel, chosen for its superior mechanical properties compared to cast or stamped alternatives. The gear undergoes a meticulous CNC machining process to achieve precise tolerances and a perfect fitment profile, ensuring smooth meshing with the oil pump drive shaft. This precision reduces wear and minimizes the risk of premature failure.

After machining, the gear is heat-treated to enhance hardness and fatigue resistance, critical for components exposed to continuous rotational forces and elevated temperatures. A corrosion-resistant coating further protects the gear from rust and environmental contaminants, extending its service life even in harsh conditions.
