Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X30-30B
The AirTAC ACEJ12 Adjustable Compact Cylinder ACEJ16X30-30B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø16mm bore and 30mm 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 ACEJ12 Adjustable Compact Cylinder ACEJ16X30-30B
A double acting ISO 21287 compact cylinder with a 16 mm bore and a 30 mm stroke that an external stop screw trims anywhere in a 0-30 mm window. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N, rising to 140.7 N at 0.7 MPa, with a theoretical peak of 20.5 kgf at 1.0 MPa. Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into slim pick-and-place heads and fixture clamps that a full-length body cannot reach.
The B code gives a male 8 mm rod end, and the M5x0.8 port keeps tubing small. A fixed TPU bumper at each end absorbs end-of-stroke shock, the hard-anodized aluminium body resists wear, and the optional -S magnet enables CMSE / DMSE switches; without -S no magnet is fitted.

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 | Force (both ways) |
|---|---|
| 0.5 MPa | 75 N |
| 0.7 MPa | 106 N |
| Max (@1.0 MPa) | 15 kgf |
ACEJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X30-30B Is Used
Small parts ejection
Trims the 30 mm stroke down to eject finished pins from a compact machining fixture, with about 60 N of usable push at 0.5 MPa.
Lab slide positioning
Male rod thread and M5x0.8 port suit benchtop slide stops where the short ISO 21287 body fits under a low guard.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X30-30B the Right Cylinder?
The stop screw only shortens the extend stroke and is 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 add the -S code if CMSE / DMSE position sensing is needed.
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 ACEJ16X30-30B FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa push is 140.7 N and pull 105.6 N, with a theoretical maximum of 20.5 kgf at 1.0 MPa. The -30 code is a 30 mm adjustment window: an external stop screw shortens the extend stroke anywhere from 0 to 30 mm. It is a mechanical end stop, not a load-holding lock, so the rod can drift on air loss.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends and FA/LB mounting options. Sensing requires the optional -S magnet code; this model has no magnet fitted, so order ACEJ16X30-30BS if CMSE or DMSE switches are needed.
