The cylinder block is the central rotating component of the hydraulic motor — housing the pistons and converting hydraulic pressure into the rotational force that powers your excavator's swing function. A worn or damaged cylinder block results in internal leakage, loss of torque, and eventual motor failure.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDirect OEM-compatible replacement for SG015, MFB30, and MFB35 swing motors\u003c\/li\u003e\n\u003cli\u003ePrecision-machined bore surfaces for accurate piston fit and minimal internal leakage\u003c\/li\u003e\n\u003cli\u003eRestores full hydraulic torque and swing motor output\u003c\/li\u003e\n\u003cli\u003eEngineered for consistent performance under high-pressure, continuous-duty operation\u003c\/li\u003e\n\u003cli\u003eBuilt to OEM specifications for a direct, reliable fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eFits SG015, MFB30, and MFB35 swing motor assemblies.
