About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X30-10B
The ACEJ16X30-10B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. An external stop screw trims the 30 mm extend stroke by up to 10 mm on site, so the usable extend range is 20-30 mm without changing the cylinder.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which makes this model easy to fit into slim fixtures, small guarding frames and dense machine layouts. A hard-anodized aluminium body carries an S45C hard-chrome plated 8 mm rod, and fixed TPU bumpers at both ends absorb end-of-stroke shock. Note that no magnet is fitted on this version; order the -S code if you later need CMSE / DMSE switch 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 | 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 ACEJ16X30-10B Is Used
Light press-fit of connectors
Pushing small PCB headers or terminal blocks into housings needs a controlled 20-30 mm stroke; the stop screw lets you dial the final position in by up to 10 mm without shimming.
Compact pick-and-place slides
On miniature gantries where every millimetre counts, the 50%-shorter body plus male rod thread makes direct coupling to small slides straightforward; add the -S magnet option later if position sensing is required.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X30-10B the Right Cylinder?
At 16 mm bore this sits in the light-duty band: it pushes 100.5 N at 0.5 MPa, while the 12 mm bore manages only 56.5 N and the 20 mm bore reaches 157.1 N. If your tooling mass or clamp force sits near 60 N of working load, this size is the sweet spot; step up to 20 mm when you need more margin. The male rod thread (B code) suits couplers and knuckles that screw on externally, and FA flange or LB foot mounts bolt to the standard ISO 21287 face. Remember the stop screw only shortens the extend stroke and is not a mid-stroke lock: on air loss the piston can still drift, so do not rely on it to hold a load.
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 ACEJ16X30-10B FAQ
The base stroke is 30 mm and the -10 code gives a 10 mm adjustment window, so the extend stroke can be trimmed anywhere from 20 to 30 mm with the external stop screw. It runs double acting 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 each end and an M5x0.8 port.
The ACEJ16X30-10B is an ISO 21287 compact cylinder: a hard-anodized aluminium body with an S45C hard-chrome plated 8 mm rod, threaded aluminium covers and fixed TPU bumpers that only decelerate the piston at each end of travel. Its body is about 50% shorter in mounting length than an ISO 15552 profile cylinder. FA flange and LB foot mounts plus I/Y rod knuckles bolt straight to the ISO 21287 face. Position sensing is not included on this version because there is no magnet; order the -S variant to enable CMSE / DMSE reed or solid-state switches.
