Airtac ACED Double-acting Compact Cylinder ACED25X45S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED25X45S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø25mm bore and 45mm 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.

About the Airtac ACED Double-acting Compact Cylinder ACED25X45S
The ACED25X45S is a double acting, double-rod compact cylinder built to the ISO 21287 short-body format. A 10 mm hard-chrome-plated S45C rod exits BOTH covers, so the 25 mm bore delivers the same 206.2 N at 0.5 MPa (288.6 N at 0.7 MPa) on every stroke, and the through-rod resists rotation and side load while the rear rod can carry a sensor flag. The -S code means the magnet is fitted, so CMSE or DMSE reed and solid-state switches mount directly in the body slots.
The hard-anodized aluminium body with threaded aluminium covers saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs, guards and gantries. A fixed TPU bumper at each end absorbs end-of-stroke energy, speed runs 30-500 mm/s over 0.15-1.0 MPa (22-145 psi) of filtered air, and the female M6x1.0 rod thread takes standard knuckles. As a rule of thumb, plan on about 124 N (roughly 12 kg lifted vertically) of real work at 0.5 MPa rather than the full 206.2 N rating.

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.
Theoretical Output Force (Ø25mm)
| 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).

Where the Airtac ACED Double-acting Compact Cylinder ACED25X45S Is Used
Symmetric jig clamping
The through-rod lets a fixture clamp from both sides of a machined aluminium bracket with one cylinder, delivering 206.2 N inward at 0.5 MPa from each rod end in a body short enough for a crowded jig plate.
Position-checked ejection
With the fitted magnet, CMSE switches confirm full extend and retract on a 45 mm eject stroke that pushes rejected plastic caps off a conveyor lane at up to 500 mm/s.
Reciprocating slide drive
Equal 288.6 N force at 0.7 MPa in both directions drives a small pick-and-place slide back and forth between hard stops, the TPU bumpers soaking up the end-of-travel shock on every cycle.
Is the Airtac ACED Double-acting Compact Cylinder ACED25X45S the Right Cylinder?
At 206.2 N per direction this 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 to 32 mm if your fixture needs more margin or down to 20 mm for lighter tooling. The 45 mm stroke is well inside the 150 mm standard range for bore 25, so it ships as a catalogue item. Mounting: FA/FB flanges, LB foot and FTC brackets bolt to the ISO 21287 face with I/Y rod knuckles. Note that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short stroke fits the compact body
- ✓ Port/thread type (PT / G)
- ✓ Add -S if you need the magnet for sensors
- ✓ Rod type (female / male B) & mount (FA/LB/CA)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Compact body: keep the stroke short and avoid side load on the rod.
- check Do not dismantle the threaded front/back covers.
- check Keep speed within the rated range; the TPU bumper absorbs stroke-end energy.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACED Double-acting Compact Cylinder ACED25X45S FAQ
Yes - the double-rod design means both strokes use the rod-side area, so output is equal either way: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa, with a peak of 42.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, speed 30-500 mm/s and -20 to +70 C.
The S code means the optional -S magnet is fitted on this model, so CMSE or DMSE reed and solid-state switches can be clipped into the body slots for end-of-stroke signalling - without the S code there is no magnet. The ISO 21287 compact body is hard-anodized aluminium about 50% shorter in mounting length than an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and FA/FB flange, LB foot or FTC mounting plus a female M6x1.0 rod thread.
