Product Description
Doosan DX55 Mini Excavator Forged Steel Front Idler Group
Heat-treated undercarriage spare parts designed for maximum durability and performance 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, enhances torque transmission efficiency, and synchronizes service life with all undercarriage components to eliminate uneven wear.
Manufactured through premium alkali phenolic resin sand casting or sodium silicate-bonded sand casting processes, this idler delivers robust construction and perfect dimensional stability. After specialized heat treatment, it achieves HRC 48-58 surface hardness with a 4-6mm hardened layer (HRC 45), providing exceptional impact and wear resistance for harsh mining and construction conditions.
Final finishing on a CK5110 large-scale CNC vertical lathe ensures precise dimensional accuracy and smooth surface finish for seamless assembly. The extended service life reduces frequent part replacements, minimizing maintenance-related safety hazards and contributing to workplace safety improvements.
Idler Characteristics
Tech-Driven Durability: Built to Outlast
  • 50% lower bearing pressure drastically reduces bearing load, doubling component lifespan
  • Splined idler-shaft connection prevents uneven wear and enhances long-term reliability
  • Heavy-duty rock guard protects against dirt, rubble 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-induced failures
  • Expanded bearing surface and optimized oil flow enhance track stability on rough terrain
Cost-Smart Engineering: Lower Total Cost of Ownership
  • Rotating shaft with stationary bushings reduces contact friction and wear significantly
  • Prolonged track life lowers operational costs by reducing downtime and part replacement frequency
  • 50% less bearing stress translates to fewer bearing failures and reduced repair expenses
