This DH360LC front track idler is a precision-machined undercarriage component designed for Doosan DH360LC excavator routine overhaul and direct part replacement. Different from ordinary standard idlers, every unit is 100% air tightness tested before delivery, effectively preventing internal oil leakage, water ingress and dust penetration during long-term field operation. As a direct manufacturer, we strictly implement full-process production and finished-product inspection, providing stable, high-sealing and durable track guide wheels for heavy-duty engineering equipment.

The biggest difference between our DH360LC idler and generic products is the independent air tightness test procedure. Each finished idler is placed in a professional pressure testing device for sealed detection to confirm no internal air leakage, ensuring the internal bearing cavity remains fully sealed. This standardized test avoids common market problems such as early oil leakage, mud infiltration and bearing rust failure under muddy, watery and dusty working conditions. All products pass dimensional inspection, surface flaw detection and sealing performance test, with factory qualification rate up to 99.8%.

• Strict Sealing Performance: Pass professional air tightness test, stable internal sealing, extend service life of internal bearings.
• Heavy-duty Wear Resistance: Standard alloy steel with precise heat treatment, anti-impact and anti-wear for long-hour operation.
• Perfect Compatibility: Strictly produced according to DH360LC original size, fully suitable for daily maintenance and equipment overhaul.
• Factory Direct Quality Control: No middleman circulation, complete inspection records, stable batch quality consistency.

Ideal for Doosan DH360LC excavator track system maintenance, routine overhaul and old part replacement, widely applicable for mining, road construction and municipal engineering scenarios. Adopt anti-rust oil, waterproof film and solid wooden box packaging to ensure intact long-distance sea transportation. We support sample inspection, batch wholesale and customized production, providing stable supply for global engineering machinery dealers and maintenance factories.
