Airtac ACE Compact Cylinder ACE12X50
The AirTAC ACE Compact Cylinder ACE12X50 is a genuine double acting ISO 21287 compact air cylinder with a Ø12mm bore and 50mm 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 ACE12X50
This AirTAC ACE12X50 is a double acting ISO 21287 compact cylinder with a 12 mm bore and 50 mm stroke. Its short body cuts mounting length by about half compared to an ISO 15552 profile cylinder, so it fits inside tight machine guards and small jigs where a full-length unit will not.
The rod is 6 mm with a female M3x0.5 thread, and the port is M5x0.8. A fixed TPU bumper at each end absorbs impact, and the hard-anodized aluminium body resists wear in continuous cycling.

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 (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 57 N | 42 N |
| 0.7 MPa | 79 N | 59 N |
| Max (@1.0 MPa) | 12 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 ACE12X50 Is Used
Small Parts Ejection
Use the ACE12X50 to eject small plastic components from an injection mold cavity. The 50 mm stroke clears the part, and the 56.5 N push at 0.5 MPa is enough to move parts under 3 kg without overstressing the mold.
Fixture Clamping
Mount this cylinder on a manual assembly bench to clamp thin sheet metal parts during drilling or riveting. The compact body fits under a workbench guard, and the fixed TPU bumper prevents noisy end-of-stroke impact on delicate edges.
Lab Valve Actuation
In a laboratory fluid-handling rig, the ACE12X50 can actuate a small pinch valve or syringe plunger. The M5x0.8 port connects easily to 4 mm tubing, and the 42.4 N pull force retracts the plunger reliably at speeds up to 500 mm/s.
Is the Airtac ACE Compact Cylinder ACE12X50 the Right Cylinder?
For lighter duty, the ACE12X25 offers the same bore with a shorter stroke for compact pick-and-place tasks. If you need more force, step up to the ACE16X50, which pushes 100.5 N at 0.5 MPa and pulls 75.4 N, giving you nearly double the thrust in a similar footprint. This ACE12X50 has no magnet, so it cannot trigger CMSE or DMSE sensors; order the -S version if you need position sensing. Mounting options include FA/FB flange, LB foot, and CA/CB clevis brackets that bolt directly to the ISO 21287 face.
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 ACE12X50 FAQ
At 0.5 MPa, push force is 56.5 N and pull force is 42.4 N. At 0.7 MPa, push is 79.2 N and pull is 59.4 N. The theoretical maximum force is 11.5 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).
The ACE12X50 follows ISO 21287, so its body is about 50% shorter than an ISO 15552 profile cylinder of the same stroke, saving space in tight fixtures. However, this model has no magnet, so you cannot mount CMSE or DMSE switches on it. Order the ACE12X50S version if you need magnetic position sensing.
