Forged Steel Undercarriage Spare Parts for D31 Heavy Duty Idler Assembly for Bulldozer
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—effectively eliminating uneven wear. The axle's rotation within fixed bearings minimizes friction, extending the overall track system lifespan.
Manufactured through premium processes including alkali phenolic resin sand casting or sodium silicate-bonded sand casting, this idler offers robust construction and perfect dimensional stability. After specialized heat treatment, it achieves HRC 48-58 surface hardness and a 4-6mm hardened layer (HRC 45), providing outstanding impact and wear resistance for harsh mining and construction environments.
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 worker exposure to safety hazards during maintenance 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 and eliminating frequent replacement hassles
  • Splined idler-shaft connection: Aligns service life with other undercarriage parts, preventing uneven wear and enhancing long-term reliability
Efficiency-Focused Design: Minimize Downtime, Maximize Uptime
  • Detachable bushed bearing blocks: Enable quick removal and servicing without disassembling the track, cutting maintenance time by 40%
  • Dedicated lubrication injectors: Deliver precise, targeted lubrication to high-wear areas, preventing friction-induced component failures
Cost-Smart Engineering: Lower Total Cost of Ownership
  • Rotating shaft + stationary bushings: Reduces contact friction and wear significantly, minimizing unplanned production stoppages
  • Prolonged track life: Lowers total operational costs by reducing downtime losses and part replacement frequency
