Power up your breaking performance with precision-engineered hydraulic breaker main body assemblies
SB40 hydraulic breaker main body
The hydraulic breaker main body assembly, often referred to as the power cell or core assembly, is the heart of your hydraulic breaker . This critical component is responsible for converting hydraulic energy into high-frequency, high-impact mechanical force, driving the tool to break through rock, concrete, and other tough materials.
For models like the SB40, SB43, and SB45, maintaining a robust and fully functional main body assembly is directly linked to crushing efficiency, operational stability, and equipment longevity.

Technical Specifications & Design Features
Our main body assemblies are built to meet exacting standards, ensuring they withstand the rigors of heavy-duty use.
Key Specifications
High-Strength Materials: Components like the piston are manufactured from high-strength alloy steel and undergo precision machining and heat treatment for superior durability and impact resistance .
Optimized Impact Energy: Engineered to deliver the ideal impact force for the respective breaker model, maximizing material break-up per blow.
Precision Fit: Manufactured to OEM-equivalent or superior tolerances to ensure seamless integration with your SB40, SB43, or SB45 breaker.
Advanced Design Features
Efficient Control Valve System: Features a precision piston control valve that swiftly alternates hydraulic flow to drive the piston’s reciprocating motion, ensuring consistent impact cycles .
Robust Piston Design: The hardened, high-carbon chromium steel piston is the primary moving component, engineered for millions of high-impact cycles without failure .
Integrated Nitrogen Gas Chamber: Utilizes pre-pressurized nitrogen to accumulate energy during the piston’s return stroke, accelerate the piston during the forward stroke, and cushion the components post-impact, enhancing efficiency and protection .
Heavy-Duty Sealing System: Comprehensive sealing with O-rings, guide rings, and composite gaskets effectively prevents hydraulic oil leaks, nitrogen loss, and contamination ingress, which are common causes of failure .
