Our Hyundai spring coil is a high-tension recoil spring designed for excavator track adjusters, maintaining optimal track tension and recoil absorption.
We operate factory direct, providing comprehensive OEM manufacturing services to global clients with precise dimensional customization.
This component prevents track derailment and downtime by resisting fatigue, deformation, and breakage under heavy impact loads.
With 20+ years of experience and ISO9001/SGS certification, Dingtai delivers consistent quality and proven durability.
Our springs use high-tensile spring steel with deep heat treatment and shot peening for superior load-bearing performance.
- Deep Quenching/Heat Treatment: Precision-controlled heat treatment ensures uniform hardness and high fatigue resistance for extended spring life.
- ISO9001/SGS Certified: Every batch is manufactured under certified quality systems, ensuring consistent material and dimensional accuracy.
- 100% QC Inspection: Each spring undergoes load testing, dimensional checks, and surface inspection before shipment.
- OEM Capabilities: We produce exact OEM replacements by matching drawings, dimensions, and performance specifications for Hyundai machines.
Our catalog of Hyundai Spring Coil includes various specifications, fully compatible with Hyundai excavators and bulldozers.

Technical Features
The spring coil operates as a recoil mechanism, absorbing track impact energy and returning the idler to maintain constant tension.
Shot peening introduces compressive stress on the surface, significantly reducing crack propagation and fatigue failure.
Progressive heat treatment ensures uniform microstructure, delivering consistent load ratings across every coil.
Applications
- Mining
- Road Construction
- Quarrying
- Demolition
- Earthmoving

Maintenance Guide
Step 1: Inspect spring coils for visible cracks, corrosion, or sagging every 500 operating hours.
Step 2: Check track tension regularly; improper tension accelerates spring fatigue and undercarriage wear.
Step 3: Replace springs in pairs when load loss exceeds 10% or visible deformation occurs.
Step 4: Use only certified OEM-compatible springs to maintain recoil performance and safety.
