In HC95 Hydraulic Rock Drill (or Hydraulic Drifter) systems, the Shank thrust 86747672 is a “critical buffer component” between the shank and the drill’s fixed housing. During rock-breaking operations, the shank transmits high-impact force (up to 15 kN for HC95) to the drill bit, generating strong axial thrust in the process. This thrust sleeve acts as a “cushion”: it distributes the thrust evenly to the housing, avoiding direct metal-to-metal contact between the shank and housing—preventing premature wear of both parts.

1. Material durability: Its thrust surface is made of heat-treated alloy steel (HRC 48-52) with a wear-resistant coating, ensuring minimal wear even after 800+ hours of heavy use.
2. Precision fit: The inner hole is machined to ±0.003mm tolerance, matching the HC95 shank’s diameter exactly—no looseness that causes vibration or leaks.
3. Corrosion resistance: The surface is treated with anti-rust plating, suitable for damp underground mines or dusty surface quarries.
