Product Description

Komatsu Construction Machinery Bulldozer OEM Undercarriage Spare Parts PC60 PC100 Front Idler Assembly
What is an Idler?
The idler features a keyed joint connecting it to the axle, which expands the bearing surface and enhances torque transmission. This design not only boosts overall reliability but also synchronizes the idler's service life with other undercarriage components. When the axle rotates inside fixed bearings, friction and wear are significantly reduced, further extending the durability of the entire assembly.
In manufacturing, the idler is crafted via either the alkali phenolic resin sand casting process or sodium silicate-bonded sand casting process. After undergoing specialized heat treatment, it achieves a minimum surface hardness of HRC48-58 and a hardened layer depth of 4-6mm (HRC45)—attributes that enable it to deliver exceptional impact resistance and wear resistance, even in harsh working environments like mining or construction.
To ensure precision, the idler is further refined on a CK5110 large-scale precision CNC vertical lathe, resulting in impeccable dimensional accuracy and superior surface finish quality. This comprehensive, multi-step manufacturing approach guarantees that the finished CHT idler delivers consistent stability during operation and a reliably long service life—while fewer replacement cycles (thanks to extended durability) also directly decrease workers' exposure to safety hazards during maintenance.
Idler Characteristics
Tech-Driven Durability: Built to Outlast
  • 50% bearing pressure reduction: Slashes bearing load to extend component life by 2x+—eliminating frequent replacements.
  • Splined idler-shaft connection: Locks in unbeatable reliability while aligning the idler's lifespan with other critical undercarriage parts.
  • Heavy-duty rock guard: Acts as a rugged barrier against dirt, rubble, and debris, shielding vulnerable components from costly damage.
Efficiency-Focused Design: Minimize Downtime, Maximize Output
  • Detachable bushing-equipped bearing blocks: Remove and service without disassembling the track—cuts maintenance time by up to 40%.
  • Dedicated lubrication injectors: Target high-wear surfaces with precise lubricant delivery, preventing friction-related failures.
  • Expanded bearing surface + optimized oil flow: Boosts track stability and responsiveness, even in rough mining conditions.
Cost-Smart Engineering: Lower TCO, Higher Returns
  • Rotating shaft + stationary bushings: Reduces contact stress and wear, slashing unplanned stoppages that eat into profits.
  • Prolonged track system life: Lowers overall mining operational costs by minimizing downtime and replacement frequency.
  • 50% less bearing stress: Directly translates to fewer bearing failures, reducing both parts costs and labor for repairs.
