Precision Spur Gear

This heavy-duty spur gear is a robust, precision-engineered component optimized for reliable power transmission in high-torque mechanical systems.

Construction & Materials

Manufactured from high-strength carbon alloy steel, it undergoes a rigorous heat-treatment process that includes carburizing and quenching, creating a hardened tooth surface (HRC 58–62) for exceptional wear resistance, paired with a tough, impact-resistant core. The gear is finished with a black oxide coating, which provides enhanced corrosion protection, reduces friction during meshing, and extends service life in dusty, damp, or otherwise harsh operating environments.

Design Features

Precision Hobbing: The gear teeth are cut using CNC hobbing to achieve an accurate involute profile, ensuring smooth, low-backlash meshing with mating gears. This precision minimizes vibration and noise, even at high rotational speeds, while maintaining consistent torque transfer.

Integrated Bore Design: The central precision-machined bore ensures a concentric, slip-free fit onto drive shafts. The stepped hub design adds structural rigidity, distributing axial loads evenly and preventing premature fatigue.

Optimized Tooth Geometry: The tooth profile is engineered to distribute contact stress across the entire tooth face, reducing the risk of pitting, scuffing, or tooth breakage. This design ensures long-term durability in continuous-duty applications.

Performance & Applications

This gear is ideal for use in heavy-duty industrial, agricultural, and construction equipment, including:

Gearboxes for conveyors, crushers, and mixers

Agricultural machinery such as tractor transmissions and harvester drives

Construction equipment like excavator and loader drivetrains

Mining and material handling systems

Its combination of rugged construction, precision engineering, and corrosion resistance makes it a dependable choice for applications where downtime is costly and performance is critical.
