Precision engineered dawn cylinder (lower cylinder body) for Montabert HC50 series hydraulic breaker. Manufactured from high-grade forged alloy steel with CNC machining and heat treatment for robust piston chamber support in demanding rock drilling and demolition applications.
The 86334299 Dawn Cylinder, also known as the Lower Cylinder Body, is a core structural component within the Montabert HC50 hydraulic breaker assembly. This cylinder houses the piston chamber and provides the primary impact zone where the piston strikes against the tool, converting hydraulic energy into powerful percussive force. Forged from high-grade alloy steel and precision CNC machined to exact OEM specifications, the dawn cylinder withstands extreme impact forces, high-frequency cyclic loading, and harsh working environments. Heat treatment achieves optimal hardness distribution for superior wear resistance while maintaining the structural integrity required for continuous heavy-duty rock breaking operations.
