MERIT Piston for Epiroc HB 4700

The internal striking piston is the dynamic core of the heavy-duty Atlas Copco / Epiroc HB 4700 hydraulic breaker. Operating in demanding quarrying and demolition sectors, this piston converts high-pressure hydraulic flow into massive kinetic force, striking the chisel directly to fracture ultra-hard rock formations.

MERIT manufactures this premium replacement piston using high-purity forged alloy steel and advanced heat treatment, ensuring it withstands millions of high-impact cycles without deformation under extreme ambient temperatures.

Technical Features of MERIT Pistons

Operating a massive hammer like the Epiroc HB 4700 demands micronic precision to maintain hydraulic stability. MERIT ensures absolute mechanical excellence through:

1. Forged Alloy Steel

Manufactured from certified alloy steel that undergoes rigorous mechanical forging. This eliminates internal porosity, granting the metal maximum fracture toughness against heavy recoil forces.

2. CNC Machining & Mirror Finish

Machined on state-of-the-art CNC grinding centers to achieve strict micronic tolerances. The sliding surfaces undergo a “mirror-like” super-finishing process, reducing friction and protecting the hydraulic seal kit from premature wear.

3. Differential Case Hardening

The bottom impact face is hardened to maximum levels to resist mushrooming and metal indentation, while the inner core retains elastic toughness to absorb reverse shockwaves without snapping.
