Hitachi EX200 Construction Machinery Bulldozer OEM Undercarriage Spare Parts Heat Treatment Front Idler Assembly

1. What is a Idler?

2. Idler Characteristic

• 2.1 Tech-Driven Durability: Built to Outlast

  • 50% reduced bearing pressure: Cuts bearing load drastically, extending component life by 2x or more and eliminating the hassle of frequent replacements.
  • Splined idler-shaft connection: Secures unrivaled reliability while aligning the idler’s lifespan with other critical undercarriage parts—avoiding uneven wear that shortens system life.
  • Heavy-duty rock guard: Serves as a tough barrier against dirt, rubble, and debris, shielding vulnerable components from damage that would lead to costly repairs or replacements.

  2.2 Efficiency-Focused Design: Minimize Downtime, Maximize Output

  • Detachable bearing blocks with bushings: Can be removed and serviced without disassembling the track, trimming maintenance time by up to 40% and getting equipment back to work faster.
  • Dedicated lubrication injectors: Deliver precise lubrication to high-wear surfaces, preventing friction-related failures and reducing unplanned downtime.
  • Expanded bearing surface + optimized oil flow: Enhances track stability and responsiveness, even in rough mining conditions where performance is critical.

  2.3 Cost-Smart Engineering: Lower TCO, Higher Returns

  • Rotating shaft + stationary bushings: Lowers contact stress and wear, cutting down on unplanned stoppages that erode profits and disrupt operations.
  • Prolonged track system life: Reduces overall mining operational costs by lessening downtime and the frequency of part replacements.
  • 50% less bearing stress: Directly leads to fewer bearing failures, lowering both parts expenses and the labor costs associated with repairs.
