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 assembly (also known as a track tensioner) for Hyundai excavators R200, R210, and R220 is a vital undercarriage component designed to maintain proper track tension during machine operation. A well-functioning adjuster ensures smooth track movement, minimizes derailment risk, and prevents premature wear on track links, rollers, and idlers.
Our adjusters are built to meet or exceed OEM performance standards, providing the same stability and durability that professional contractors expect from genuine Hyundai components.
High-Quality Materials and Engineering
Each Hyundai-style track adjuster assembly is manufactured using premium alloy steel for both the cylinder body and piston rod. The internal surfaces are precision-honed for excellent sealing performance, while the rod surface undergoes induction hardening and chrome plating to resist corrosion and abrasion.
Key engineering advantages include:
- Cylinder body: Made from forged steel with uniform wall thickness for high pressure endurance.
- Piston rod: Heat-treated and hard chrome plated (≥ HRC 52) to withstand constant extension and retraction.
- Sealing system: Uses imported high-pressure seal kits to prevent oil leakage and maintain consistent tension.
- Spring group: Fabricated from high-strength alloy spring steel to absorb shocks and maintain track tension automatically.
This robust structure ensures that the tensioning system remains stable even in harsh construction, quarry, or forestry environments.
Working Principle
The track adjuster assembly consists mainly of a hydraulic cylinder, recoil spring, and front idler yoke connection.
During machine operation, the assembly automatically adjusts the track tension based on load and terrain changes. Hydraulic oil pressure pushes the piston forward to tighten the track, while the recoil spring compresses to absorb impacts. This mechanism:
- Keeps the track chain properly aligned and tensioned.
- Reduces excessive slack that could cause track jumping.
- Protects the idler and sprocket from uneven stress.
- Proper tension also improves undercarriage efficiency and reduces overall wear on the track group.

The diagram demonstrates the robust sealing system and precision machining that ensures smooth piston extension and contraction even under high pressure and high impurity environments.
Precision Manufacturing Process
Each unit undergoes a rigorous multi-stage manufacturing process, ensuring dimensional accuracy and durability:
- CNC Machining – ensures precise cylinder bore and piston fit.
- Heat Treatment & Surface Hardening – enhances fatigue resistance.
- Chrome Plating & Polishing – provides anti-rust performance.
- Seal Assembly & Pressure Testing – confirms hydraulic reliability under working conditions.
- Final Painting & Packaging – ensures a clean, corrosion-protected finish for global shipment.
Every adjuster is 100% tested before delivery to guarantee perfect operation and leak-free performance.
