Product Description
Forged Steel Heavy-Duty Doosan Construction Machinery Undercarriage Spare Parts - DH220 Excavator Front Idler Group
What is an Idler?
The CHT idler is engineered for uncompromising durability and workplace safety, featuring advanced structural design and precision manufacturing. Its keyed idler-axle joint widens the bearing contact area, enhances torque transmission efficiency, and synchronizes the idler's service life with all undercarriage components, effectively eliminating uneven wear. The axle's rotation within fixed bearings minimizes friction, extending the overall track system's lifespan.
Manufactured through premium processes including alkali phenolic resin sand casting or sodium silicate-bonded sand casting, the idler ensures robust construction and strict dimensional stability. After specialized heat treatment, it achieves 48-58 HRC surface hardness with a 4-6mm deep hardened layer (45 HRC), delivering exceptional impact and wear resistance for harsh mining and construction conditions.
Final finishing on a CK5110 large-scale CNC vertical lathe guarantees precise dimensional accuracy and smooth surface finish for seamless assembly. The extended service life reduces frequent part replacements, minimizing maintenance safety hazards and linking long-lasting performance to workplace safety improvements.
Idler Characteristics
Tech-Driven Durability: Engineered to Outlast Harsh Conditions
  • 50% lower bearing pressure: Drastically reduces bearing load, doubling component lifespan and eliminating frequent replacements
  • Splined idler-shaft connection: Synchronizes service life with undercarriage components, preventing uneven wear
  • Heavy-duty rock guard: Protects internal components from dirt and debris in demanding environments
Efficiency-Focused Design: Minimize Downtime, Maximize Uptime
  • Detachable bushed bearing blocks: Enable quick removal without track disassembly, cutting maintenance time by 40%
  • Dedicated lubrication injectors: Provide precise lubrication to high-wear areas, preventing friction failures
  • Expanded bearing surface + optimized oil flow: Enhances track stability and operational responsiveness on rough terrain
Cost-Smart Engineering: Lower Total Cost of Ownership
  • Rotating shaft + stationary bushings: Reduces contact friction and wear significantly
  • Prolonged track life: Lowers operational costs by reducing downtime and part replacements
  • 50% less bearing stress: Reduces bearing failures, slashing parts and repair costs
