Shop HITACHI EX30 KUBOTA KX61 SERIES FINAL DRIVE PLANTARY GEAR BUSHING 20 X 25 X 13MM | Tonkee®

The planetary gear bushing is a small but essential part of the final drive system in these compact excavators.

It is designed to provide support and reduce friction within the planetary gear assembly. This assembly consists of multiple gears that work together to distribute torque and power from the excavator's hydraulic motor to the tracks, allowing the machine to move efficiently and effectively.

The dimensions of the planetary gear bushing, 20 x 25 x 13mm, are crucial for ensuring a proper fit within the final drive system. The 20mm inner diameter ensures that it fits snugly onto the shaft, preventing any play or wobbling that could lead to increased wear and reduced efficiency. The 25mm outer diameter is designed to fit precisely within the gear housing, ensuring proper alignment and distribution of forces. Finally, the 13mm width provides the necessary support and stability to the gears, allowing them to rotate smoothly and transmit power effectively.

One of the key specifications to consider when selecting a planetary gear bushing is the material from which it is made.

These bushings are typically constructed from high-quality, durable materials such as bronze or steel. These materials are chosen for their ability to withstand the high loads, pressures, and temperatures that occur within the final drive assembly. They are also resistant to wear and corrosion, ensuring a long service life for the bushing.

Proper maintenance and replacement of the planetary gear bushing are essential to ensure the continued performance and reliability of the excavator's final drive system. Over time, the bushing may experience wear and tear due to the constant movement and stresses it undergoes during operation. When the bushing becomes worn or damaged, it can lead to increased friction, decreased efficiency, and potential damage to other components within the final drive system.
