1. Brief Introduction to ST52 cylinder barrel
Cylinder barrel is also called Honed tube. Cylinder barrel is the main body of hydraulic cylinder, and its inside hole is commonly manufactured by use of boring, reaming, rolling and honing and other precision machining processes to enable the piston and seals and bearing to slide smoothly, thereby ensuring the sealing effect and reducing wear and tear; The cylinder barrel bear a lot of hydraulic pressure, and therefore, it should have sufficient strength and rigidity.
