Product Specifications
HYUNDAI R800 Track Front Idler Assembly (Part No. 81ND-13050GG) - Mining & Heavy-Duty Construction Grade
Introduction:
The Track Front Idler Assembly is a critical undercarriage component responsible for guiding the track chain, maintaining proper track tension, and absorbing forward impacts. For Hyundai R800 series excavators operating in severe mining, quarrying, and heavy construction environments, the integrity of this assembly directly dictates machine stability, mobility, and overall undercarriage life. HAN GONG/DPW PARTS manufactures this 81ND-13050GG Front Idler Assembly to meet or exceed stringent OEM specifications, utilizing mining-quality materials and engineering for maximum durability and performance under continuous high-load conditions.
Product Overview & Specification:
OEM Part Number: 81ND-13050GG
Compatible Machine Model: Hyundai Robex R800 Series Mining and Heavy-Duty Excavators.
Assembly Type: Complete Front Idler Assembly (including idler wheel, shaft, seals, housing, and flanges as per OEM design).
Core Function: Guides the track chain, maintains track tension via the recoil mechanism, and absorbs shock loads from ground engagement.
Design Standards: Engineered to match HYUNDAI original dimensions, mounting points, and performance tolerances.
Key Technical Features & Manufacturing Excellence:
Forged & Heat-Treated Idler Wheel:
Manufactured from high-carbon, high-chromium alloy steel forgings for superior grain structure and strength.
Subjected to controlled quenching and tempering (heat treatment) processes to achieve an optimal balance of surface hardness (for wear resistance) and core toughness (for impact resistance).
Precision-machined rolling surface ensures smooth track link engagement and minimizes friction-induced wear.
Heavy-Duty Sealing System:
Utilizes a multi-layered, labyrinth-style sealing configuration combined with high-grade nitrile rubber (NBR) or polyurethane seals.
Effectively excludes abrasive contaminants (dust, silt, slurry) and retains internal lubricant, preventing premature failure of bushings and bearings.
Designed for extended service intervals even in high-contamination environments typical of mining operations.
Robust Internal Components:
Bushings/Bearings: Features oversized, induction-hardened bushings or tapered roller bearings capable of sustaining radial and axial loads from uneven terrain and side-loading.
Shaft: High-tensile strength alloy steel shaft, precision-ground for perfect fit and alignment, secured with high-grade fasteners.
Recoil Mechanism (if applicable): Built to OEM specifications, allowing precise track tension adjustment and necessary recoil to absorb shock loads.
Mining-Quality Construction:
All structural components, including the idler housing and flanges, are fabricated from heavy-gauge steel plates with reinforced welding seams.
Corrosion protection through sandblasting (SA 2.5 standard) and application of industrial-grade primers and paints.
Precision Engineering for Compatibility:
Each assembly undergoes strict dimensional verification to ensure perfect fit with the R800 excavator’s track frame, recoil springs, and track chain links.
Guarantees proper track alignment, reducing abnormal wear on adjacent undercarriage parts (track links, rollers, sprockets).
Application & Operational Benefits:
Primary Industry: Large-scale mining (open-pit, coal, metal), major earthworks, quarrying, and heavy infrastructure projects.
Benefits:
Extended Service Life: Superior materials reduce wear rates, lowering cost-per-hour and total cost of ownership.
Enhanced Machine Stability: Maintains correct track geometry and tension for safer, more stable operation on slopes and rough ground.
Reduced Downtime: Reliable construction minimizes unscheduled failures and component change-outs.
Protects Undercarriage Investment: Prevents premature wear on costly track chains and other rollers by ensuring proper alignment and tension.
