The AirTAC Airtac ACED Double-acting Compact Cylinder ACED25X35S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø25mm bore and 35mm 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 ACED25X35S is a double acting, double-rod compact cylinder built to ISO 21287: a piston rod exits both covers, so the 25 mm bore delivers an identical 206.2 N at 0.5 MPa (288.6 N at 0.7 MPa) in each direction. The S in the code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped onto the body slot for end-of-stroke sensing.
The hard-anodized aluminium body with an S45C hard-chrome-plated rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, and carries a fixed TPU bumper at both ends. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs and guarding. As a rule of thumb, plan on roughly 123 N of usable work force, and the through-rod will lift about 10 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
| Pressure | Force (both ways) |
|---|---|
| 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).

| 25 | Bore size in mm. |
| ×35 | Stroke length in mm. |
| S | Optional built-in magnet for CMSE / DMSE sensors (omit for no magnet). |
| B | Rod type: B = male thread; blank = female thread. |
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 through-rod clamps a machined aluminium housing from both sides with an equal 206.2 N at 0.5 MPa, and the fitted magnet signals clamp-complete to the PLC via a CMSE switch.
A 35 mm stroke nudges cartons sideways on a conveyor at 30-500 mm/s; the back-end rod carries a sensor flag so the DMSE switch confirms retract without extra hardware.
The double rod resists rotation on a small vertical lift of about 10 kg with a 2:1 margin, and the compact body fits inside a benchtop gantry where a full-length profile cylinder will not.
At 206.2 N per side, this 25 mm bore sits between the 20 mm size (117.8 N at 0.5 MPa) and the 32 mm size (345.6 N at 0.5 MPa), so step up if your tooling needs more grip force. The 35 mm stroke is well inside the 150 mm maximum standard stroke for bore 25. 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. Mount with FA/FB flange, LB foot or FTC brackets and I/Y rod knuckles on the ISO 21287 face; the female M6x1.0 rod thread and PT ports suit standard fittings.
Quick checklist
The 25 mm double-rod design gives 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa, equal in both directions because both strokes use the rod-side area; at 1.0 MPa the maximum is 42.0 kgf. The -S magnet is fitted on this model, so CMSE or DMSE reed and solid-state switches mount in the body slot. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, port M5x0.8, female M6x1.0 rod thread.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it suits tight jigs, guards and gantries. A fixed TPU bumper at both ends absorbs end-of-stroke energy; it is not adjustable and it never holds or brakes a load, so use a rod lock or pilot check where position must be kept with air off. FA/FB flange, LB foot and FTC brackets plus I/Y knuckles bolt straight to the standard face.
