About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X60-20S
The ACEJ16X60-20S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 60 mm stroke by up to 20 mm on site, giving a usable 40-60 mm range without changing the cylinder. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa those figures rise to 140.7 N and 105.6 N. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body cannot.
For sizing, plan on roughly 60 N of real work at 0.5 MPa (about 0.6 of the push rating), which corresponds to lifting about 5 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries an 8 mm S45C hard-chrome rod with a female M4x0.7 thread, a fixed TPU bumper at each end absorbs end-of-stroke energy, and the fitted -S magnet works with CMSE / DMSE switches for end-of-stroke sensing. Speed range is 30-500 mm/s.

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 ACEJ16X60-20S Is Used
Small-part press fitting
Seating dowels or bearings into aluminium housings on an electronics assembly bench, where the 40-60 mm trimmed stroke matches shallow press depth and 100.5 N is enough for light interference fits.
Gated conveyor diverting
Swinging a lightweight guide arm on a packaging line, with CMSE switches confirming extend and retract positions through the fitted magnet.
Fixture clamp in a test rig
Holding small PCB or sensor modules inside a guarded test station, where the compact body fits under a low cover and about 5 kg vertical lift equivalent covers the part weight.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X60-20S the Right Cylinder?
At 100.5 N push (0.5 MPa) this 16 mm bore suits light clamping and part-presenting duty. Step down to a 12 mm bore (56.5 N) for very light loads, or up to a 20 mm bore (157.1 N) when the work needs more margin. Note that the stop screw is a mechanical end stop only: on air loss the piston still drifts, so do not treat it as a load-holding lock. FA flange or LB foot mounts bolt to the ISO 21287 face, and the fitted -S magnet lets you add CMSE / DMSE switches at either end.
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 ACEJ16X60-20S FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa, 140.7 N push and 105.6 N pull; theoretical maximum is 20.5 kgf at 1.0 MPa. It is double acting with a 16 mm bore, 60 mm stroke adjustable over a 20 mm window (40-60 mm usable), M5x0.8 ports, 8 mm rod with female M4x0.7 thread, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, and speed 30-500 mm/s.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body and fixed TPU bumpers at both ends. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots for end-of-stroke detection. FA flange and LB foot mounts fit the standard ISO 21287 face.
