• Key function: Converts hydraulic pressure into mechanical impact force, drives shank and drill bit for rock-breaking
In HC20 Hydraulic Rock Drill (or Hydraulic Drifter) systems, the Strike piston 86668738 is the “power core of rock-breaking”—it’s responsible for translating high-pressure hydraulic oil (up to 1800 psi for HC20) into cyclic mechanical impact force (up to 12 kN), which directly strikes the shank to drive the drill bit into rock. This part endures extreme stress: each working cycle involves high-speed reciprocation (1300-1500 bpm) and repeated metal-to-metal collision, making its wear rate predictable—and why Montabert specifies a 800-hour mandatory replacement cycle.
With short delivery times (no 2-3 week waits like generic pistons), you can stock up in advance to meet the 800-hour replacement cycle—no last-minute delays. Add in competitive pricing that beats many non-OEM options, and this Strike piston 86668738 becomes an essential choice for mines prioritizing productivity, cost-control, and equipment reliability. Whether you’re drilling in underground coal mines or surface limestone quarries, it ensures your HC20 maintains consistent, strong impact power for every 800-hour cycle.
