Cylinder tubes

Cylinder tubes

Our cylinder tubes are manufactured from high-quality seamless steel tubes or cold drawn tubes and can be supplied in honed, skived and roller burnished, or custom machined conditions. With stable material quality and precise dimensional control, they are suitable for OEM production, maintenance, and replacement applications.

Product Details

Summary


Cylinder Tubes play an important role in the performance and durability of hydraulic and pneumatic cylinders. The quality of the tube directly affects sealing efficiency, friction performance, piston movement, and overall service life. For this reason, cylinder tubes require good straightness, accurate inner diameter tolerance, and smooth surface finish.

Our hydraulic cylinder tubes are available in a wide range of materials, sizes, and processing conditions to meet different industrial requirements. According to customer drawings or technical specifications, we can provide raw tubes, honed tubes, SRB tubes, and machined cylinder tubes for different applications.
