radial force on hydraulic cylinder stem

[G.Moroni]

Hello everyone,

I am new in the forum and this is my first discussion.
in short: we are designing a clamping equipment for structural components in c45 1.1191. In the first phase I need to use hydraulic cylinders for positioning on fixed side feedback and then carry out the seal with magnetic plane (img. 4).
here arises my question: going to work 140mm out axis the cylinder rod would go under a radial force that would cause excessive wear of the bearings (img.1). to overcome the problem I thought of inserting a side guide (img. 2). Do you think that could be a good solution? would it be better to put the guide to the center directly on the floor(img.3)? I was advised to use a spherical joint at the end of the cylinder stem to cancel the radial force and make it totally axial, could it be a solution?

Thank you in advance.

theory and practice also say that cylinders, tires or hydraulics that are, must bear only and exclusively axial loads, radial loads compromise seals.

Have you thought of implementing a knee pad mechanism?

any type of cylinder must bear and pour only purely axial thrusts. put the spherical snout could make fit the push but the mold mechanics must be affixed, guided so that there are no lateral pushes due to the swing.
the day-to-day system will certainly allow you to be more aligned and resist transversal forces. certainly some extra money will cost.
