Product Description
CAT 3408242/5400649 E390 Excavator Undercarriage Spare Parts - Precision Forged Steel Guide Wheel Track Front Idler
What is an Idler?
The CHT idler delivers exceptional durability and operational safety through advanced engineering and precision manufacturing. Its innovative keyed joint between idler and axle expands the bearing contact area, enhances torque transmission, and synchronizes the idler's lifespan with other undercarriage components to prevent uneven wear. The axle's rotation within fixed bearings significantly reduces friction, extending the entire track system's service life.
Manufactured using premium processes including alkali phenolic resin sand casting or sodium silicate-bonded sand casting, this idler features 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 outstanding impact and wear resistance for the most demanding mining and construction applications.
Idler Characteristics
Tech-Driven Durability: Built to Outlast
  • 50% lower bearing pressure significantly reduces bearing load, doubling component lifespan and eliminating frequent replacement requirements
  • Splined idler-shaft connection aligns service life with other undercarriage components, preventing uneven wear and enhancing long-term reliability
  • Heavy-duty rock guard provides robust protection against dirt, rubble, and debris in demanding mining and construction environments
Efficiency-Focused Design: Minimize Downtime
  • Detachable bushed bearing blocks enable quick removal and servicing without track disassembly, reducing maintenance time by 40%
  • Dedicated lubrication injectors deliver precise lubrication to high-wear areas, preventing friction-induced failures
  • Expanded bearing surface and optimized oil flow enhance track stability and responsiveness in rough terrain
Cost-Smart Engineering: Lower Total Cost of Ownership
  • Rotating shaft with stationary bushings reduces contact friction and wear, minimizing unplanned stoppages
  • Prolonged track life reduces operational costs by decreasing downtime and part replacement frequency
  • 50% less bearing stress results in fewer bearing failures, reducing parts procurement and repair labor costs
