1. What is a Idler?

2. Idler Characteristic

2.1 Superior Performance & Durability

• Reduces bearing pressure by 50%: Eases bearing loads and significantly extends component service life.
• Heavy-duty rock guard: Robust stone shields block soil, rubble, and debris to prevent damage to critical parts.
• Expanded bearing surface & optimized oil distribution: Enhances overall track system performance and operational stability.

2.2 Boosted Productivity

• Splined connection (idler + shaft): Improves reliability and synchronizes the idler’s lifespan with other undercarriage components.
• Detachable bearing blocks with bushings: Allow removal without disassembling the track, minimizing maintenance time.
• Dedicated lube injectors: Precisely supply lubricant to high-wear surfaces, reducing friction-related downtime.

2.3 Lower Total Cost of Ownership

• 50% reduced bearing stress: Directly lowers bearing loads and extends component life, cutting replacement costs.
• Rotating shaft + stationary bushings: Minimizes contact stress and wear, reducing unplanned stoppages.
• Prolonged track system lifespan: Lowers mining operational expenses by reducing frequent replacements and downtime.
