Airtac ACE Compact Cylinder ACE25X80
The AirTAC Airtac ACE Compact Cylinder ACE25X80 is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 80mm 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 ACE Compact Cylinder ACE25X80
This AirTAC ACE25X80 is a double acting ISO 21287 compact cylinder that extends and retracts its 10 mm rod with air pressure on both strokes. At 0.5 MPa it delivers 245.4 N of push force and 206.2 N of pull force, while at 0.7 MPa the push rises to 343.6 N and pull to 288.6 N. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight jigs and guards where a full-length cylinder will not. A fixed TPU bumper at each end absorbs the end-of-stroke impact, and the hard-anodized aluminium body with a roller-burnished bore resists wear in continuous cycling.
For a real-world load, plan for about 147 N of safe work at 0.5 MPa, which is roughly 15 kg lifted vertically with a 2:1 safety margin. The rod end is female with an M6x1.0 thread, and the port is M5x0.8. This unit has no magnet fitted, so it cannot accept CMSE or DMSE sensors; order the optional -S code if you need position sensing. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), and speed range is 30-500 mm/s.

Where the Airtac ACE Compact Cylinder ACE25X80 Is Used
Fixture Clamping
Clamp small parts in a CNC fixture with 245.4 N push at 0.5 MPa, using the compact body to fit under a workholding table where a longer cylinder would not clear.
Carton Tamping
Tamp folded cartons in a packaging line with 80 mm stroke to settle contents before sealing, relying on the fixed TPU bumper to reduce noise at high cycle rates.
Divider Gate
Operate a small diverter gate on a conveyor with 206.2 N pull force at 0.5 MPa, using the M5x0.8 port for quick connection to a compact valve manifold.
Is the Airtac ACE Compact Cylinder ACE25X80 the Right Cylinder?
For a lighter load, the ACE20X80 offers 157.1 N push at 0.5 MPa, while stepping up to the ACE32X80 gives 402.1 N push at the same pressure. Since the ACE25X80 has no magnet, choose the ACE25X80S if you need to mount CMSE or DMSE switches for position feedback. The ISO 21287 face accepts FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, plus I and Y rod knuckles, so it drops into standard fixtures. Note that this cylinder does not hold its position when air is lost or the valve is centred; use a rod lock or pilot check valve for load holding.
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 ACE Compact Cylinder ACE25X80 FAQ
At 0.5 MPa, push is 245.4 N and pull is 206.2 N. At 0.7 MPa, push is 343.6 N and pull is 288.6 N. The theoretical maximum force at 1.0 MPa is 50.1 kgf. The rod is 10 mm diameter, the port is M5x0.8, and the maximum standard stroke for this bore is 150 mm.
Yes, it is an ISO 21287 compact cylinder with a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder. It has a fixed TPU bumper at both ends, not an adjustable cushion, and speed is 30-500 mm/s. This model has no magnet, so CMSE or DMSE sensors cannot be mounted unless you order the optional -S version with a magnet.
