Designed to withstand continuous torque and impact forces in HC25 Hydraulic Rock Drills, the Drive Component 86221595 outperforms generic alternatives. While common carbon steel parts are prone to fatigue and 断裂 under heavy loads, this OEM component is forged from high-grade alloy steel with integrated reinforcing ribs. Rigorously tested under mine conditions, it maintains structural integrity for the full 800-hour replacement cycle, with a price point that undercuts comparable non-OEM parts.
