pneumatic cylinder fixing with spherical joint

[Fabio24]

Good morning to all, question of the week, I attach a sketch of the system. I have a pneumatic cylinder working as a shock absorber for a trolley mounted on a ball recirculation guide. in practice the trolley receives a push from the outside and the cylinder makes as a compensator. to the assembly tell me that it would have been better to mount a spherical snout on the cylinder thread, to compensate for any disalignments. and it could actually be there. But I was thinking, being the cylinder tied to the plate through its counterdado, even mounting a spherical snout, if there was a misalignment the stem of the cylinder would still receive a not purely axial thrust. according to you is correct as a solution?

pneumatic/hydraulic cylinders must work only in push and traction, any radial component shall affect the duration of the seals. it is always useful to mount on the stem or spherical joints or attacks to "baionetta" in order to compensate for any disalignment or hypervincular system.

In this case a floating joint must be mounted.

If you only had to dampen a race end then it's much better to use an object made specifically, such as decelerators ace or enidine. Consider that a pneumatic cylinder used in that way can see the pressure in the chamber rise to dangerous levels, unless a servovalve has been inserted.

yes the cylinder chamber is powered by a proportional pressure regulator. no is not an end but a trolley that makes a slight cushioning. My doubt is that if there was really a misalignment, the spherical joint still does not make the two parallel axes. perhaps it is better the floating joint recommended by @cacciatorino

If you use zipper on one side and spherical joint on the other you get the same function as the floating joint and you should save something.

I thought about it myself.... So if I only use the spherical joint and hold the cylinder as it is now, do I not solve the right problem? because the cylinder on one side is bound
