How to connect the piston and the 304 Hydraulic Precision Piston Rod

The piston rod is a connecting member that supports the work of the piston, and is generally used in cylinders and cylinder motion executing members. Its function is to connect the piston and the crosshead to transmit the force acting on the piston and drive the piston to move. So how do the pistons and cylinder rods connect? The universal connection between the piston and the piston rod is a threaded connection. This connection is easy to operate. However, the disadvantage is that the thread is easy to fall off, so some anti-loosening joints must be used, such as shrink-proof screws, anti-loosening washers, thread glue, etc. Except for the threaded connection, the connection between the piston and the piston rod is mostly a snap connection. This type of connection has strong bearing capacity and reliable operation, and is usually used when the piston rod is large. The card key is also very convenient to install, but requires special tools. Depending on the diameter of the piston rod, the size and thickness of the key used will vary. Another connection method is welding. This type of connection is rarely used, and is mainly used in some compact cylinders, which are used when there is no additional size space for keys and nuts. When welding, the length of the piston rod thread is about 2 mm shorter than the thickness of the piston, so the welding effect is good.
