86746450 Front Bearing for Montabert HC95 Rock Drill
Front Bearing - Part Number 86746450
The 86746450 Front Bearing is a precision load-bearing and guiding component at the core of the Montabert HC95 rock drill's front-end assembly. It supports the rotating shank and drill bit, absorbing radial and axial loads during high-frequency impact and rotary cycles, while maintaining perfect alignment to minimize friction and wear.
Manufactured to Montabert's exact OEM specifications, this front bearing guarantees a seamless drop-in fit with the HC95's front guide and shank assembly, preserving operational stability and drilling efficiency. 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 of your Montabert rock drill.
