The 86747045 Thrust Liner is a precision load-bearing and wear-resistant component exclusively engineered as a genuine OEM part for the Montabert HC95 rock drill. As a critical axial load distributor in the drill’s rotary and impact systems, it absorbs high thrust forces generated during hard-rock drilling, reduces friction between moving parts, and protects the gearbox and bearing assemblies from abrasive wear and thermal damage.

Manufactured to Montabert’s exact factory specifications, this thrust liner guarantees a seamless drop-in fit with the HC95’s gear housing and shaft assembly, preserving operational stability and extending component lifespan. In harsh underground mining, tunneling, and quarrying environments—where dust, moisture, and extreme vibration are constant—it maintains dimensional stability under high pressure and temperature, directly enhancing the reliability and service life 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 86747045 Thrust Liner is an indispensable replacement part for your Montabert rock drill in all core operational scenarios:

• Absorbing axial thrust loads in Montabert HC95 rock drills during underground mining blasting hole drilling (up to 40m depth) in hard-rock formations like granite and basalt.
• Protecting gearbox bearings in Montabert HC95 rock drills used for tunnel anchor and support hole drilling in wet, dusty infrastructure construction projects.
• Reducing friction and wear in Montabert HC95 rock drills during quarrying operations for stone cutting, rock excavation, and pre-splitting tasks.
• Restoring factory-spec load-bearing performance during full overhauls or shank assembly replacement of Montabert rock drills.
