OEM 86748019 RP Liner for Montabert HC95 Rock Drill

The 86748019 RP Liner (Reverse Piston Liner) is a precision cylinder and sealing component at the core of the Montabert HC95 rock drill’s hydraulic percussion system. It serves as the high-precision guide and wear-resistant inner wall for the strike piston, maintaining perfect axial alignment during high-frequency impact cycles while preserving hydraulic pressure integrity.

Manufactured to Montabert’s exact OEM specifications, this RP liner guarantees a seamless drop-in fit with the HC95’s cylinder housing and piston assembly, directly determining the drill’s impact efficiency and service life. In harsh underground mining, tunneling, and quarrying environments—where dust, moisture, and extreme vibration are constant—it resists wear, scuffing, and thermal fatigue, ensuring reliable performance of your Montabert rock drill.

• Genuine Montabert Precision for Perfect HC95 Compatibility
