Hydraulic cylinder honing barrel

What is Hydraulic cylinder honing barrel?

The cylinder barrel is the main body of the hydraulic cylinder, and its inner hole is generally manufactured by precision machining processes such as boring, reaming, rolling or honing, so that the piston and its seals and supporting parts can slide smoothly, thus ensuring the sealing effect and reducing wear; The cylinder barrel must bear a large hydraulic pressure, so it needs to have sufficient strength and stiffness.
