The 86748720 Ring is a precision positioning and wear-resistant component for the Montabert HC95 rock drill, serving as a critical interface within the drill’s hydraulic cylinder and shank assembly. This robust annular ring maintains precise axial alignment of internal moving parts, absorbs lateral loads during high-impact drilling cycles, and protects sensitive components from abrasive wear and contamination.

Manufactured to Montabert’s exact factory specifications, this ring guarantees a seamless drop-in fit with the HC95’s cylinder housing and piston assembly, preserving hydraulic pressure integrity and operational stability. In harsh underground mining, tunneling, and quarrying environments—where dust, moisture, and extreme vibration are constant—it resists fatigue, scoring, and corrosion, directly extending the service life and reliability 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 86748720 Ring is an indispensable replacement part for your Montabert rock drill in all core operational scenarios:

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