Kubota Hydraulic Cylinder for Excavator U35 U165 U183 Dipper Arm, Boom, Bucket Cylinder

Main Components of Kubota Hydraulic Cylinder

Piston Seal
The piston seal is essential for keeping hydraulic pressure separated on both sides of the piston. It prevents fluid from leaking across the piston, which would otherwise reduce power and efficiency. Built to handle high pressure and constant motion, this seal makes sure the cylinder delivers consistent force.

Rod Cartridge
The rod cartridge is the housing unit for key sealing elements such as the rod seal, wiper, and sometimes the bearing. Its design makes maintenance and replacement much easier. By sealing the area where the rod exits the cylinder, it prevents oil leakage and blocks dirt or moisture from entering.

Rod
The rod is the solid shaft that connects the piston inside the cylinder to the external machine component. As hydraulic pressure moves the piston, the rod transfers this motion outward to perform lifting, pushing, or pulling tasks. Strength and surface finish are critical here, since the rod must resist bending, wear, and corrosion during operation.

Piston
The piston sits inside the cylinder barrel and moves when hydraulic fluid applies pressure to one side. Acting as the main moving part, it converts fluid power into linear mechanical force. The piston is firmly attached to the rod, so its motion directly drives the machine’s working function.
