Piston

The document discusses piston rods, which transmit kinetic energy from the piston to the workpiece. Piston rods are generally circular for double action cylinders that require sealing between the rod and guide bush. They can be the same diameter as the piston for rams or have different cross sections and attachment mechanisms for different types of single action cylinders and jacks.

Piston Rod: -
When diameter of piston rod is almost equal to piston diameter then generally it is called as
RAM.
But in general all large size of piston rods are called "RAM". Piston rod is a mechanical
member,
which transmits kinetic energy, which got developed at piston, to the work-piece. It is
circular
in cross-section in case of double action cylinder, as hydraulic sealing is required between
piston
rod and guide bush. In ram type of single action cylinder, piston rod is also circular in cross
action, while in piston type single action cylinder in which sealing is not required between
piston
rod and guide bush, piston rod may be of any type of cross section. For example in case of
lock nut
type of single action jack, piston rod has thread on its entire length. Piston-rod is also called
as
plunger. It could extend from both the end of cylinder, and it could be hollow also. Piston-rod
could
be attached to other component by means of threading, eye bolt type arrangement, or groove
and
split coupling arrangement etc
