Precision engineered bearing holder plate for Montabert HC50 series hydraulic rock drill drifters. Manufactured from high-strength ductile iron with exact OEM specifications for stable bearing positioning and reliable structural support in demanding mining and tunneling applications.
The 86344116 Bearing Holder Plate is a critical structural component within the Montabert HC50 hydraulic rock drill drifter front head assembly. This plate securely positions and retains the main bearing assembly, ensuring precise shaft alignment and smooth rotational operation under extreme percussive loads. Precision cast from high-grade ductile iron (QT500-7), the bearing holder plate is machined to exact tolerances for perfect fitment within the drifter housing. It withstands continuous high-frequency impact forces, vibration, and harsh underground drilling conditions while maintaining bearing alignment accuracy critical to drifter performance and service life.
