Airtac ACED Double-acting Compact Cylinder ACED25X45
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED25X45 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 ACED25X45
The ACED25X45 is a double acting compact cylinder built to ISO 21287, with a piston rod leaving BOTH covers. Because each stroke works on the rod-side area, output is identical in push and pull: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa. The through-rod resists rotation and modest side load, and the rear rod end doubles as a mounting point for a sensor flag or a symmetric fixture.
The hard-anodized aluminium body with an S45C hard-chrome-plated rod keeps the envelope short - roughly 50% of the mounting length of an ISO 15552 profile cylinder - so it slots into tight jigs and guarding. A fixed TPU bumper at each end absorbs end-of-stroke shock. At 0.5 MPa the 206.2 N rating works out to about 21 kgf, so plan on lifting roughly 10 kg vertically with a 2:1 margin, or budget about 124 N for real work after friction and losses.

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 ACED25X45 Is Used
Fixture clamping on CNC pallets
The 206.2 N equal push and pull at 0.5 MPa clamps and releases aluminum workpieces with identical force, while the 45 mm stroke fits shallow fixture plates where a full-length cylinder cannot.
Push-push transfer between belt lanes
With a rod on both covers, one ACED25X45 pushes parts off a conveyor from either side at equal force, and the through-rod keeps the tool plate square at 30-500 mm/s.
Lab sample press with position flags
In compact analytical equipment, the rear rod carries a sensor flag for external detection, and the short ISO 21287 body tucks under a benchtop guard; order the -S code to read CMSE / DMSE switches.
Is the Airtac ACED Double-acting Compact Cylinder ACED25X45 the Right Cylinder?
For this 45 mm stroke, compare the 20 mm bore (117.8 N at 0.5 MPa) if the load is light, or step up to the 32 mm bore (345.6 N at 0.5 MPa) for heavier tooling. The 25 mm bore sits comfortably in between for clamping and transfer tasks. The 45 mm stroke is well inside the 150 mm maximum standard stroke for this bore, so it ships as a catalog item. 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. Mounting brackets (FA/FB flange, LB foot, FTC) and I/Y rod knuckles bolt to the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switches; this model without the S code carries no magnet.
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 ACED25X45 FAQ
Yes - the double-rod design exposes the rod-side area on both strokes, so force is equal pushing and pulling: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa. At 1.0 MPa the maximum is 42.0 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, running on air filtered to 40 um at 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end to soften end-of-stroke impact. Sensing is not fitted as standard: order the -S magnet option and CMSE / DMSE switches can be slid onto the body's magnet slots. The 45 mm stroke is a standard length for the 25 mm bore (up to 150 mm), and FA/FB flange, LB foot or FTC brackets plus I/Y knuckles mount directly.
