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
• High-Impact Durability for Mining Operations
• Hydraulic Sealing & Debris Protection
• Optimized Design for Maintenance Efficiency

The 86748019 RP Liner is an indispensable replacement part for your Montabert rock drill in all core operational scenarios:

• Guiding the strike piston in Montabert HC95 rock drills during underground mining blasting hole drilling (up to 40m depth) in hard-rock formations like granite and basalt.
• Maintaining hydraulic pressure integrity in Montabert HC95 rock drills used for tunnel anchor and support hole drilling in wet, dusty infrastructure construction projects.
• Protecting internal components of Montabert HC95 rock drills during quarrying operations for stone cutting, rock excavation, and pre-splitting tasks.
• Restoring factory-spec percussion performance during full overhauls or cylinder replacement of Montabert rock drills.
