Shop HITACHI EX EX-3 ZAXIS ZX SERIES FINAL DRIVE PINION SHAFT | Tonkee®

The pinion shaft is typically constructed from high-strength alloy steel or a similar robust material to withstand the extreme stresses and loads encountered during excavator operation.

Its design ensures durability and longevity, even when subjected to demanding working conditions.

Precision Engineering:

Manufacturers, such as Tonkee®, adhere to strict engineering and quality standards to produce pinion shafts that precisely match the specifications of Hitachi EX-3 ZAXIS ZX Series excavators. This precision engineering ensures a seamless fit and optimal performance.

Compatibility:

The Hitachi EX-3 ZAXIS ZX Series final drive pinion shaft is specifically designed to be compatible with this series of excavators, ensuring that it integrates seamlessly with the rest of the drive system.

Splined Design:

The pinion shaft typically features splines that engage with the final drive gear. This spline design ensures a secure and efficient transfer of power, minimizing slippage and maximizing torque delivery to the tracks.

Heat Treatment:

To enhance its strength and durability, the pinion shaft undergoes a heat treatment process. This process involves heating the shaft to a specific temperature and then cooling it rapidly to improve its hardness and toughness.

Surface Coating:

Many pinion shafts are coated with a protective layer to resist corrosion and wear.

This coating can be a specialized paint or plating that helps extend the life of the shaft, especially in challenging environmental conditions.

Precision Machining:

The manufacturing process involves precision machining to create a smooth and accurately dimensioned pinion shaft. This precision is crucial to ensure that the shaft meshes flawlessly with other components in the final drive assembly.

Weight and Dimensions:

The dimensions and weight of the pinion shaft are typically specified to match the original equipment manufacturer (OEM) standards precisely. This ensures that it can be easily installed as a direct replacement for the original part.

Installation Considerations:

Proper installation of the pinion shaft is crucial to ensure its functionality and longevity. It must be correctly aligned and securely fastened to the final drive assembly following the manufacturer's guidelines.
