Airtac ACE Compact Cylinder ACE40X80
The AirTAC ACE Compact Cylinder ACE40X80 is a genuine double acting ISO 21287 compact air cylinder with a Ø40mm bore and 80mm stroke, 1/8" 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 ACE40X80
This AirTAC ACE40X80 is a double acting ISO 21287 compact cylinder with a 40 mm bore and 80 mm stroke. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a full-length unit will not. The fixed TPU bumper at each end absorbs impact, and the S45C hard-chrome rod resists wear in repetitive cycles.
The 1/8" port and M8x1.25 female rod thread match standard fittings. Since this unit has no -S code, there is no magnet fitted, so CMSE or DMSE sensors cannot be mounted unless you order the optional -S version.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 572 N |
| 0.7 MPa | 880 N | 800 N |
| Max (@1.0 MPa) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACE Compact Cylinder ACE40X80 Is Used
Jig Clamping
Mount this ACE40X80 on a CNC fixture to clamp small aluminium parts during drilling. The 628.3 N push force at 0.5 MPa holds workpieces securely, while the short body leaves room for chip guards and coolant lines.
Carton Tamping
Use it in a packaging line to tamp folded cartons before sealing. The 80 mm stroke matches the carton depth, and the fixed TPU bumper prevents shock to the frame at high cycle rates up to 500 mm/s.
Gate Actuation
Fit this cylinder on a small safety gate or access door in a food processing line. The 571.8 N pull force retracts the gate reliably, and the compact body fits within the guard frame without protruding.
Is the Airtac ACE Compact Cylinder ACE40X80 the Right Cylinder?
For lighter indexing tasks, the ACE32X25 offers 402.1 N push at 0.5 MPa, while the ACE50X80 steps up to 981.7 N push for heavier clamping. This 40 mm bore with 80 mm stroke suits medium-duty push and pull operations where space is limited. The fixed TPU bumper only softens end-of-stroke impact; it does not hold a load if air pressure is lost, so use a rod lock or pilot check valve for position holding. Choose FA or FB flange, LB foot, or CA/CB clevis mounts to match your fixture, and remember the magnet is optional -S, not standard.
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 ACE40X80 FAQ
At 0.5 MPa, push is 628.3 N and pull is 571.8 N. At 0.7 MPa, push rises to 879.6 N and pull to 800.5 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. Operating pressure range is 0.15-1.0 MPa (22-145 psi), with proof pressure at 1.5 MPa (215 psi).
No, this specific unit has no magnet because the -S code was not ordered. The magnet is optional and must be specified as -S at purchase. Without it, CMSE or DMSE reed or solid-state switches cannot be mounted. If you need position sensing, order the ACE40X80S version.
