Configure it to the machine.
| Code | Mounting | Common applications |
|---|---|---|
| MF3 / MF4 | Round flange at head / cap end | Press rams, injection moulding, bridge lifting |
| MP3 / MP5 | Rear clevis (plain) | Mobile equipment, linkage drives |
| MT4 | Intermediate trunnion | Swinging loads, cranes, tilting mechanisms |
| MS2 | Side lugs / foot mount | Machine tools, stationary fixtures |
| MX5 | Rod end threaded, stud rear | Compact actuation, short stroke |
| Spherical | Self-aligning clevis (spherical bearing) | Misalignment compensation, heavy earthworks |
| Code | Cushion type | Use case |
|---|---|---|
| 00 | None | Low speeds, no inertia |
| F0 | Fixed cushion, rod side only | Vertical loads, compact envelope |
| FF | Fixed cushioning both ends | Moderate speeds, symmetric duty |
| A0 | Needle-valve adjustable, rod side | Tunable deceleration |
| AA | Needle-valve adjustable, both ends | Heavy inertia, variable speeds |
| SA | Slow-damping profile with needle valve | High mass, vertical application |
