Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X75-20
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X75-20 is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø16mm bore and 75mm stroke, M5×0.8 air ports and a hard-anodized aluminium body.

About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X75-20
The ACEJ16X75-20 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 75 mm stroke anywhere within the ordered 20 mm window, giving a usable range of 55-75 mm without changing hardware. At 0.5 MPa the 16 mm bore delivers 100.5 N push and 75.4 N pull, rising to 140.7 N push at 0.7 MPa, which suits light clamping, ejecting and positioning tasks on small fixtures.
Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim slides and guarded cells where a full-length body will not reach. The hard-anodized aluminium body carries an S45C hard-chrome rod and a fixed TPU bumper at each end. In practice, plan for roughly 60 N (about 6 kg of thrust) of real work at 0.5 MPa, or lift about 5 kg vertically with a 2:1 margin. Note the stop screw is a mechanical end stop only: on air loss the piston drifts, so it never holds a load mid-stroke.

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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 75 N |
| 0.7 MPa | 141 N | 106 N |
| Max (@1.0 MPa) | 21 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X75-20 Is Used
Small-part press fitting
Presses dowel pins or bearings into aluminium housings on electronics assembly benches, where the 55-75 mm adjustable range matches varying part heights and about 60 N of usable force at 0.5 MPa is enough.
Light part ejection from nests
Kicks finished plastic caps or stamped clips off a nest on a rotary indexing table; the compact body fits under the tooling plate where a full-length cylinder cannot.
Gated inspection station
Drives a swing-gate or stopper in a vision-check cell; order the -S magnet version to add CMSE / DMSE switches for extend and retract confirmation.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X75-20 the Right Cylinder?
Check the load both ways: at 0.5 MPa this 16 mm bore pushes 100.5 N, while the smaller 12 mm bore manages only 56.5 N and the next size up, the 20 mm bore, reaches 157.1 N. If your tooling needs more than about 60 N of usable force, step up. The female M4x0.7 rod thread takes standard knuckle accessories, and FA flange or LB foot mounts bolt to the ISO 21287 face. Position feedback requires the optional -S magnet code with CMSE or DMSE switches; this model has no magnet fitted. Ports are M5x0.8 on this bore, and 75 mm is the maximum standard stroke for bore 16.
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 ACEJ12 Adjustable Compact Cylinder ACEJ16X75-20 FAQ
Bore 16 mm, stroke 75 mm with a 20 mm adjustment window (usable 55-75 mm). Push is 100.5 N and pull 75.4 N at 0.5 MPa; at 0.7 MPa push is 140.7 N and pull 105.6 N. Theoretical maximum is 20.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, port M5x0.8, female rod thread M4x0.7.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA flange or LB foot mounts bolt straight to the standard face. Position sensing is not fitted as standard: order the optional -S magnet code to enable CMSE or DMSE reed or solid-state switches; without -S there is no magnet. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the stop screw trims the extend stroke only - it is not a mid-stroke lock.
