Gears for Heavy Equipment

Gears are the heart of every transmission and drive system, transforming engine power into controlled motion, torque, and mechanical force. At 3GEN Export, we supply premium-quality gears for heavy equipment that guarantee precise torque transfer, long service life, and unmatched reliability across all construction, mining, and drilling applications.

Our range includes spur gears, bevel gears, planetary gears, and ring gears, all manufactured from carburized alloy steel and ground to OEM specifications for smooth, efficient performance. Designed for use in excavators, wheel loaders, dozers, cranes, and drilling rigs, these gears deliver consistent power and precision under the harshest working conditions.

The Backbone of Transmission Systems

Precision Engineering for Performance

Every heavy machine depends on accurate gear engagement for seamless operation. Poorly machined gears can lead to noise, vibration, and torque loss. 3GEN Export eliminates these risks through precision CNC machining, heat treatment, and surface finishing, resulting in gears that maintain perfect alignment and balance.

Our gears undergo hardness testing, dimensional inspection, and tooth-profile accuracy checks to ensure flawless meshing in transmission systems.

Built for Endurance

Our transmission gears are engineered from case-hardened steels such as 20MnCr5 and 8620, providing excellent wear resistance and fatigue strength. The heat-treated outer layer ensures durability, while the tough core maintains elasticity under heavy loads. This combination delivers years of uninterrupted service in high-torque operations.

Complete Range of Gears

Spur Gears

Spur gears are the most common gear type in heavy equipment, transmitting power between parallel shafts. Known for their simplicity and reliability, 3GEN Export spur gears are designed for quiet operation, minimal backlash, and high efficiency.

Our spur gears are used in gearboxes, final drives, and pump assemblies, ensuring direct torque transmission with reduced mechanical stress.

Bevel Gears

Bevel gears enable power transmission between intersecting shafts, commonly found in differentials and steering mechanisms. 3GEN Export bevel gears feature precision-ground teeth for optimal load distribution, smooth meshing, and minimal vibration.

Each bevel gear is tested for concentricity and balance to guarantee silent, efficient performance even under high torque.

Planetary & Ring Gears

Planetary gears provide high torque density in compact designs, making them ideal for drive systems, excavator swing mechanisms, and drilling rigs. Our planetary gear sets include sun, planet, and ring gears, all manufactured to tight tolerances for synchronized operation.

Ring gears, machined from alloy steel and induction-hardened, ensure perfect tooth contact for stable rotation under extreme conditions.

Helical & Crown Gears

For applications requiring quiet operation and high load capacity, we offer helical gears that provide smoother engagement and reduced stress on the shaft.
Crown gears are available for special-angle torque transfer systems in cranes, drills, and heavy lifting machinery.

Applications Across Heavy Equipment

3GEN Export’s gears are used in a wide range of machines and transmission systems, including:

• Excavators and wheel loaders – for swing, drive, and travel mechanisms.

• Cranes and drilling rigs – for torque multiplication and rotational motion.

• Dozers and graders – for powertrain assemblies.

• Haul trucks and dumpers – for gear reduction and differential operation.

• Winches and hoists – for controlled lifting and load management.

Our gears are designed for continuous, high-load operations, providing the perfect balance of power, durability, and noise control.
