Hydraulic Cylinder Barrel – STKM 13C Honed & Skived Tube for Cylinder Manufacturing
1. Product Overview
A hydraulic cylinder barrel is the core component of any hydraulic system, acting as a pressure vessel to house the piston and retain fluid under high pressure.
At Chengxin, we manufacture hydraulic cylinder barrels using high-quality cold drawn, honed, or skived & roller burnished steel tubes, offering:
High dimensional accuracy
Excellent inner bore surface finish
Full customization based on engineering drawings
We supply STKM 13C hydraulic cylinder barrels in a variety of sizes, supporting custom machining, welding, and finishing for OEM and aftermarket applications.
