D155 D355 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% 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.

2.2 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.

2.3 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.
