CAT Excavator Hydraulic Breaker Piston Anti Fracture For Jack Hammer Reinforced
42CrMo CAT H Breaker Piston Small / Medium / Heavy Anti-Fracture Impact Power Spare Parts For Excavator Hammer
CAT H series hydraulic breaker piston is the core power transmission component applicable to full CAT H series breakers, divided into small, medium and heavy duty specs for H160/H180, H220/H260 and H310/H360/H410 respectively. It converts hydraulic pressure into powerful striking energy, covering light landscaping, municipal demolition and large-scale hard rock quarry crushing projects.
Manufactured with premium 42CrMo alloy steel via one-piece integral forging and multi-stage gradient heat treatment. The striking end maintains high surface hardness to resist long-term abrasion, while the main rod body possesses excellent toughness to avoid transverse fracture under light, medium or heavy continuous impact loads.
The piston surface adopts precision turning and mirror grinding to form ultra-smooth outer circle, matching tightly with cylinder inner bore. Perfect concentric fit reduces friction loss, lowers hydraulic oil leakage and extends service life of matched seal kits and front guide bushing.
Small size piston fits mini excavator light work; medium piston suits road renovation and city demolition; thickened heavy-duty piston supports non-stop hard rock mining. Each piston passes raw material inspection, hardness test and continuous impact endurance verification to meet OEM interchange standards.
Full model stock supports small retail maintenance orders and large bulk wholesale for construction contractors and machinery rental firms. Custom length, diameter and oil groove processing service can be provided for global machinery repair factories and spare parts dealers.
