CAT H55E Hydraulic Hammer Piston CrMo42 Excavator Rock Breaker Spare Parts
-
Reduced internal stress design: The H55E piston assembly operates inside a suspension-buffered power cell that helps absorb recoil and vibration. This protects both the piston and the carrier machine from shock loading.
-
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..
-
Simplified serviceability: The E-Series redesign reduced internal part count by roughly 47% versus older D-Series models, making piston-area maintenance and teardown faster.
