The Reusable Pin 86624160 is a versatile connecting component for HC25 Hydraulic Rock Drills, used to link various structural and transmission parts while transmitting lateral forces. Generic pins made from ordinary carbon steel often bend or deform within 1200-1500 hours of heavy use, disrupting component alignment. This OEM pin is manufactured from 40Cr alloy steel, heat-treated to HRC 45-50 for high shear strength (≥600MPa) and resistance to bending. Its precise diameter tolerance (±0.002mm) ensures a tight fit in component holes, maintaining alignment across multiple uses until bending or breakage requires replacement.
