Which Mounting Should You Choose?
A mounting connects the cylinder to the machine. If the load always moves in one direction, use a rigid mounting — feet or a flange. If the load moves through an arc, the cylinder must pivot: a rear hinge, a middle trunnion or a place (floor) bracket, with a clevis or a spherical eye on the rod end.
| Item | Where it fits | What it does |
|---|---|---|
| Foot mount | Cylinder end caps | Rigid mounting on a surface parallel to the axis |
| Flange | Front or rear cap | Rigid mounting square to the axis, in-line thrust |
| Joint (rear hinge) | Rear cap | Lets the cylinder pivot on a pin |
| Place bracket | Machine | Counterpart of the rear hinge |
| Middle trunnion | Body centre | Pivot at mid-body for long strokes |
| Clevis with circlip | Rod end | Pin secured by a circlip |
| Clip-on clevis | Rod end | Tool-free quick fitting |
| Spherical rod eye | Rod end | Absorbs small misalignment and prevents side load |
Frequently Asked Questions
Why does the mounting matter?
The wrong mounting side-loads the rod and wears the bearing and seals, shortening cylinder life considerably.
Circlip or clip-on clevis?
The circlip version is more secure under vibration; the clip-on version is quicker to fit and remove.
How do I size the mounting?
By the cylinder bore and standard (ISO 15552 or CETOP); state the cylinder model in your order.
