The 101157291 guiding ring is a precision-aligned and wear-resistant protective component designed specifically for the Montabert HC95 hydraulic rock drill. Mounted between the drill rod and the housing, it plays two key roles: first, it keeps the piston centered during high-speed reciprocating motion (up to 1800 times per minute), eliminating lateral contact with the housing; second, it acts as a low-friction barrier between the piston and housing, preventing direct metal-to-metal contact and thus extending the service life of these two core components.

1. Alignment Accuracy: The ring’s inner bore fits the HC95 piston with minimal clearance (0.02–0.03mm), while the outer diameter locks tightly into the housing—ensuring the piston stays centered during every impact cycle.
2. Lubrication Holes: The integrated radial holes (visible in product images) facilitate hydraulic fluid flow between the ring, piston, and housing—creating a self-lubricating film that reduces friction and heat buildup.
3. Vibration Dampening: The ring’s rigid steel construction absorbs micro-vibrations from the piston, reducing fatigue stress on the drifter’s housing.
