Description
SG015 / MFB30 / MFB35 Cylinder Block Rotor for Swing Motor
Rebuild your swing motor's rotating group from the ground up with this precision-machined cylinder block rotor, designed as a direct OEM-compatible replacement for SG015, MFB30, and MFB35 series swing motor assemblies. 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.
Key Features
- Direct OEM-compatible replacement for SG015, MFB30, and MFB35 swing motors
- Precision-machined bore surfaces for accurate piston fit and minimal internal leakage
- Restores full hydraulic torque and swing motor output
- Engineered for consistent performance under high-pressure, continuous-duty operation
- Built to OEM specifications for a direct, reliable fit
Compatibility
Fits SG015, MFB30, and MFB35 swing motor assemblies. Please verify your motor model and part number before ordering to ensure correct fitment.
