The piston rod products, involved in the below, the main are:

Question 1: when reaches the piston rod, the thrust and speed of the output and the piston rod back when the output of the tension and speed are the same?

Question 2: piston rod fastening nut to loosen, the reason is what?

These two problems, is a concrete solution to below, so that everyone can through their study, to further to the piston rod in the product.

Question 1: when reaches the piston rod, the thrust and speed of the output and the piston rod back when the output of the tension and speed are the same?

It is definitely not the same, because the force is determined by the working pressure and piston diameter, and the force is more than return to pull. For speed, this is the same with speed ?
