KOMAC KB3500 Hydraulic Hammer Piston CrMo42 Excavator Rock Breaker Spare Parts

• Efficient Oil Cooling Gallery (Certain Models): Some KB3500 pistons incorporate a cooling gallery behind the ring lands. This allows engine oil to circulate and draw heat away from the critical piston crown, reducing thermal stress and preventing melting or cracking.

• Optimized Ring Grooves: Hardened ring grooves for the top compression ring to resist wear and micro-welding, crucial for long ring seal life and preventing blow-by..

• Balanced Weight & Strength: The design prioritizes longevity over extreme lightweight performance, making it ideal for endurance.
