Product Overview
The 472-7770 is an advanced Heavy Penetration Long Life Bucket Tooth incorporating ARM (Abrasion Resistant Material) technology, specifically engineered for Caterpillar 990K, 990H, and 992K wheel loaders. This premium Ground Engaging Tool (GET) combines aggressive penetration capabilities with extended service life, delivering superior performance in the most demanding digging conditions. Designed for hard rock excavation, compacted materials, and abrasive applications, it represents the pinnacle of wear resistance and digging efficiency.
Key Features & Technical Advantages
Advanced Penetration Geometry with ARM Technology: Features an aggressively tapered profile optimized for maximum penetration force concentration. The specialized ARM reinforcement in critical wear zones provides up to 35% longer service life compared to standard penetration teeth, ensuring sustained cutting performance in tough ground conditions while significantly reducing replacement frequency.
Enhanced Structural Reinforcement: Engineered with strategic material distribution in high-stress areas, combining penetration efficiency with exceptional durability. The robust construction features additional wear material in the nose and side wings, providing superior resistance to both abrasive wear and impact damage throughout extended service intervals.
Premium Alloy Steel with Advanced Hardening: Fabricated from high-grade, heat-treated alloy steel with specialized ARM technology, achieving an optimal balance of extreme surface hardness and core toughness. The advanced metallurgical composition ensures maximum resistance to wear while maintaining the impact strength necessary for heavy penetration applications.
Precision OEM Integration: Manufactured to Caterpillar's exact specifications, guaranteeing perfect fitment and optimal force transmission on 990K, 990H, and 992K wheel loader adapter systems. The precise engineering ensures seamless compatibility and maintains original equipment digging geometry for maximum efficiency.
Optimized Weight Distribution: With an engineered weight of 51.4 kg, this tooth achieves the perfect balance between penetration force and operational stability. The carefully calculated mass distribution enhances digging efficiency while minimizing stress on the entire ground engaging tool system, contributing to reduced fuel consumption and faster cycle times.
