Shop HITACHI EX30 SERIES FINAL DRIVE PLANETARY SUN GEAR 16T 32.5MM HEIGHT | Tonkee®

The planetary sun gear is an integral part of the final drive assembly in compact excavators, including the Hitachi EX30 series.

The final drive is responsible for transmitting power from the engine to the tracks, enabling the excavator's movement. The planetary sun gear plays a pivotal role in this process by engaging with other planetary gears within the final drive to control torque and speed, ultimately propelling the machine forward or backward.

Construction and Materials:
This specific planetary sun gear is designed for compatibility with the Hitachi EX30 series of compact excavators. It is manufactured to exacting standards, using high-quality materials that ensure durability and longevity. The gear is typically made from hardened steel or alloy steel, which can withstand the significant forces and stresses encountered in heavy-duty construction applications.

Tooth Count and Profile:
The planetary sun gear is characterized by its 16 teeth. The number of teeth on a gear is crucial as it directly influences the gear ratio, which in turn affects the excavator's speed and torque output. The gear's teeth are precision-cut to mesh seamlessly with other gears within the final drive, ensuring smooth and efficient power transmission.

Height:
The height of this planetary sun gear is 32.5mm. The gear's height is an essential dimension that determines its compatibility and fitment within the final drive assembly. A precise height measurement is crucial to guarantee proper alignment and engagement with other gears, preventing premature wear and damage to the components.

Compatibility and Interchangeability:
Tonkee® is a trusted brand known for providing high-quality replacement parts for heavy machinery, including excavators like the Hitachi EX30 series.

This planetary sun gear is designed to be a direct replacement for the original gear in the final drive, ensuring compatibility and ease of installation. Its interchangeability with the OEM gear simplifies maintenance and repairs, reducing downtime and costs.

Performance and Reliability:
The performance of the planetary sun gear directly affects the overall performance of the excavator's final drive system. Its precise construction, tooth profile, and material quality contribute to efficient power transmission, minimizing energy loss and maximizing excavator productivity. Furthermore, the durability of this gear ensures reliable operation even in demanding construction environments.
