40CR Hard Chrome Plated Piston Rod

APPLICATIONS OF THE CHROMED PISTON RODS

Since the main function of the chrome plated piston rod is to transmit torque and bear loads, it can be used in various mechanical systems with linear reciprocating motion. For example, it is more suitable for various types of hydraulic cylinders, air pneumatic cylinders, construction machinery, packaging machinery, woodworking machinery, conveying machinery, textile machinery, printing and dyeing machinery, die-casting machines, injection molding machines, automobile manufacturing and other machinery guide rods , top rod, etc.
