About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X75-50S
The ACEJ16X75-50S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 75 mm stroke by up to 50 mm on site, giving a usable range of 25-75 mm without changing the cylinder. 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. In practice, plan on roughly 60 N of real work at 0.5 MPa, which lifts about 5 kg vertically with a 2:1 margin.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures and guarding where a full-length body will not fit. The hard-anodized aluminium body carries an S45C hard-chrome rod, a fixed TPU bumper at both ends, and the fitted -S magnet, so CMSE or DMSE switches can be clipped on for end-of-stroke sensing.

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 ACEJ16X75-50S Is Used
Small-part press fitting
Presses bearings or bushings into aluminium housings on electronics assembly benches, where the 25-75 mm trim range lets one cylinder serve several part heights.
Position-verified clamping
Clamps PCB jigs or small brackets with CMSE switch feedback confirming full clamp, useful in automated test stations with tight access.
Compact ejection in slim tooling
Ejects finished parts from narrow machining or molding fixtures where the short body fits inside the fixture plate and a profile cylinder cannot.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X75-50S the Right Cylinder?
Size up to the ACEJ20X30-20 (157.1 N push at 0.5 MPa) if 100.5 N is marginal, or down to the ACEJ12X50-10 (56.5 N) for lighter clamping. The 50 mm window means the extend stroke can be set anywhere from 25 to 75 mm; remember the stop screw is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA flange or LB foot mounts bolt to the ISO 21287 face, and the fitted magnet accepts CMSE / DMSE switches.
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 ACEJ16X75-50S FAQ
Push is 100.5 N and pull 75.4 N at 0.5 MPa; at 0.7 MPa push reaches 140.7 N, with a theoretical maximum of 20.5 kgf at 1.0 MPa. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a fixed TPU bumper at both ends and an M5x0.8 port.
The -50 code is a 50 mm adjustment window: a stop screw shortens the extend stroke by up to 50 mm, so the usable range is 25-75 mm. Because the S code is ordered, the magnet is fitted, and CMSE or DMSE reed or solid-state switches can be mounted in the body slots for end-of-stroke detection. FA flange and LB foot mounts bolt straight to the ISO 21287 face.
