SG04 Cylinder Block Detail Display
What is a Swing Motor Cylinder Block?
A cylinder block (piston block) in an excavator swing motor is a critical hydraulic component that channels high-pressure oil to drive the swing motion. Failures here cause power loss, noise, and rotation lag. Replacing it with a precision-machined part like the SG04 ensures your swing motor remains responsive and powerful.
