Описание продукта
Mini Excavator Doosan DH80 High Precision Forged Steel Front Idler Group
Heat treatment undercarriage spare parts designed for superior durability and workplace safety in demanding mining and construction applications.
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, boosts torque transmission efficiency, and synchronizes the idler's service life with all undercarriage components—effectively eliminating uneven wear.
Manufactured through alkali phenolic resin sand casting or sodium silicate-bonded sand casting, these premium processes ensure robust construction and strict dimensional stability. After specialized heat treatment, the idler achieves 48-58 HRC surface hardness and a 4-6mm deep hardened layer (45 HRC), delivering exceptional impact and wear resistance for harsh mining and construction conditions.
Final finishing is precision-machined on a CK5110 large CNC vertical lathe, guaranteeing superior dimensional accuracy and smooth surface finish for seamless assembly. The extended service life reduces maintenance frequency, minimizing worker exposure to on-site safety hazards.
Idler Characteristics
Tech-Driven Durability: Built to Outlast
  • 50% lower bearing pressure: Drastically reduces bearing load, doubling component lifespan and eliminating frequent replacement hassles
  • Splined idler-shaft connection: Aligns service life with other undercarriage parts, preventing uneven wear and enhancing long-term reliability
  • Heavy-duty rock guard: Protects against dirt, rubble and debris in demanding mining/construction environments
Efficiency-Focused Design: Minimize Downtime
  • Detachable bushed bearing blocks: Enable quick removal and servicing without disassembling the track, cutting maintenance time by 40%
  • Dedicated lubrication injectors: Deliver precise lubrication to high-wear areas, preventing friction-induced failures
  • Expanded bearing surface + optimized oil flow: Boosts track stability and responsiveness in rough terrain
Cost-Smart Engineering: Lower Total Cost of Ownership
  • Rotating shaft + stationary bushings: Reduces contact friction and wear, minimizing unplanned stoppages
  • Prolonged track life: Lowers operational costs by reducing downtime losses and part replacement frequency
  • 50% less bearing stress: Reduces bearing failures, slashing parts procurement and repair labor costs
