Cylinder Barrels

Cylinder Barrels

Our hydraulic cylinder barrels are available in different materials, sizes, and processing conditions, including honed tubes, skived and roller burnished tubes, and customized barrel machining. They are suitable for OEM manufacturing, hydraulic repair, and industrial replacement applications.

Product Details

Summary


Cylinder Barrels are usually manufactured from high-quality seamless steel tubes or precision cold drawn tubes. According to different application requirements, the inner surface can be processed by honing or skiving and roller burnishing to achieve accurate inner diameter tolerance and smooth surface finish.

As one of the most important parts of a hydraulic cylinder, the cylinder barrel directly affects sealing performance, piston movement, and service life. Our products are supplied with reliable dimensional control, good straightness, and stable material quality, making them suitable for construction machinery, agricultural equipment, lifting systems, and industrial machinery.
