The AirTAC Airtac ACED Double-acting Compact Cylinder ACED25X5S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø25mm bore and 5mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.
The ACED25X5S is a double acting, double-rod ISO 21287 compact cylinder from AirTAC with a 25 mm bore and a very short 5 mm stroke. A piston rod exits both covers, so the output force is equal in both directions: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa either way, because both strokes work on the rod-side area. The through-rod resists rotation and light side load, and the rear rod can carry a sensor flag or a second tooling plate.
The hard-anodized aluminium body with an S45C hard-chrome-plated rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, which makes a 5 mm nudge stroke easy to fit inside tight jigs and guards. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clamped into the body slots for end-of-stroke detection. As a planning figure, expect roughly 124 N of usable work at 0.5 MPa, and the rod lifts about 10 kg vertically with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke energy, and speed spans 30-500 mm/s.

|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

ACE-family variants: ACE (double acting), ASE / ATE (single acting push / pull), ACED (double rod), ACEJ (adjustable stroke), TACE / TACED (non-rotating twin-guide yoke). Mounting accessories: FA / FB flange, LB foot, CA / CB clevis, CR, SDB pivot, FTC; plus I and Y knuckles. Thread PT (blank) / G.
The 5 mm stroke and 206.2 N per direction at 0.5 MPa are ideal for kicking a machined aluminium bracket off its locating pin after a drilling cycle, with the through-rod keeping the pusher square.
With the -S magnet fitted, CMSE or DMSE switches confirm the 5 mm gate is fully open before a vision camera on a pharmaceutical blister line fires its shot.
About 124 N of usable force at 0.5 MPa stamps a date code into a plastic cap on a bottling line, and the rear rod carries a second marker for dual-sided branding.
At 25 mm bore the ACED25X5S sits mid-range: step down to the 20 mm bore for 117.8 N at 0.5 MPa, or up to the 32 mm bore for 345.6 N if the clamp needs more grip. The 5 mm stroke is well inside the 150 mm maximum standard stroke for this bore, so it ships as a standard build. Remember that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put. Mounting brackets (FA/FB flange, LB foot, FTC) plus I and Y rod knuckles bolt to the ISO 21287 face, and the female M6x1.0 rod thread takes standard tooling studs. PT ports are M5x0.8 on this bore.
Quick checklist
Yes. Because a rod exits both covers, both strokes use the rod-side area, so force is equal either way: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa. The maximum rating for this 25 mm bore is 42.0 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, speed 30-500 mm/s, and temperature -20 to +70 C.
The ACED25X5S carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches clamp into the body slots to signal both rod positions. Deceleration at each end comes from a fixed TPU bumper, which simply absorbs the last of the travel. The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA/FB flange, LB foot or FTC brackets bolt straight to its face.
