Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The track adjuster is a key component of the undercarriage, responsible for maintaining the correct chain tension as the excavator moves forward and backward. In the ZAX200-5G, it works by pushing the front idler forward through a hydraulic grease mechanism, keeping the track properly aligned and avoiding slippage or derailment.
Equally important, the recoil spring inside the adjuster absorbs shock and vibration from rough terrains—such as rock, gravel, or uneven ground. This protective action reduces structural stress on the frame, idler shaft, and track chain, ultimately improving the excavator’s efficiency and reducing the likelihood of breakdowns.
Advanced Manufacturing & Materials
We include a detailed cross-section diagram and structural drawing to help visualize internal functionality. These images show:
- The hydraulic piston chamber
- The coil-type recoil spring absorbing impact
- The grease inlet valve for adjusting tension
- Internal support bushings and shock collars
This structure is designed to optimize load distribution and pressure resistance, ensuring stable, long-term operation.
Material Selection & Manufacturing Process
To guarantee strength and reliability, our ZAX200-5G adjuster is manufactured using top-grade materials and precision methods:
- Cylinder Body: Made from forged 40Cr or 45# steel, known for excellent fatigue strength and wear resistance. Surface is heat-treated (HRC 48–55) for optimal hardness.
- Recoil Spring: Crafted from 60Si2Mn alloy spring steel, coiled and stress-relieved to ensure elasticity under load without cracking or deformation.
- Piston Rod: CNC-machined to tight tolerances and mirror-polished to prevent seal wear and oil leakage.
- Seals & Coating: Equipped with multi-lip oil seals and dust protection rings. Finished with anti-rust paint or black oxide coating for corrosion resistance.
Each unit undergoes strict quality control, from forging inspection to hydraulic pressure testing, ensuring smooth operation even in harsh working environments.
