This precision bushing features a dual-material construction with hardened 4140 steel exterior (HRC 58-62) and oil-impregnated bronze interior, providing exceptional wear resistance in high-load pivot points. Designed specifically for cutter head linkages and gathering arm mechanisms, it withstands impact loads up to 18 tons in hard rock applications.
The micro-porous bronze core contains 20% volume oil reservoir, ensuring continuous lubrication for 2,000+ hours in high-dust environments. Each bushing is precision-ground to ±0.015mm tolerance and undergoes magnetic particle inspection to guarantee zero subsurface defects.
