The 86334109 Thrust Lining is a critical load-bearing and wear-protection component exclusively engineered as a genuine OEM part for the Montabert HC50 rock drill. As a precision thrust washer, it absorbs axial loads generated during high-impact drilling cycles, reducing friction between rotating and stationary components while protecting critical parts from wear and fatigue.

Manufactured to Montabert’s exact factory specifications, this thrust lining guarantees a seamless drop-in fit with the HC50’s gearbox and bearing assembly, preserving operational stability and extending component lifespan. In harsh mining, tunneling, and quarrying environments—where dust, moisture, and extreme vibration are constant—it resists abrasion and heat buildup, directly enhancing the reliability and service life of your Montabert rock drill.

• Genuine Montabert Precision for Perfect HC50 Compatibility
• High-Impact Durability for Mining Operations
• Hydraulic Sealing & Debris Protection
• Optimized Design for Maintenance Efficiency

The 86334109 Thrust Lining is an indispensable replacement part for your Montabert rock drill in all core operational scenarios:

• Absorbing axial loads in Montabert HC50 rock drills during underground mining blasting hole drilling (up to 30m depth) in hard-rock formations like granite and basalt.
• Protecting gearbox components in Montabert HC50 rock drills used for tunnel anchor and support hole drilling in wet, dusty infrastructure construction projects.
• Reducing friction in Montabert HC50 rock drills during quarrying applications for stone cutting, rock excavation, and pre-splitting tasks.
• Restoring factory-spec load-bearing performance during full overhauls or gearbox replacement of Montabert rock drills.
