About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X20-10B
The ACEJ16X20-10B is a double acting ISO 21287 compact cylinder with a 16 mm bore and 20 mm stroke, and its external stop screw trims the extend stroke anywhere within the ordered 10 mm window, giving a usable range of 10-20 mm. 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, with a theoretical 20.5 kgf at 1.0 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures, guards and gantries.
The hard-anodized aluminium body carries an S45C hard-chrome plated 8 mm rod, fixed TPU bumpers absorb end-of-stroke energy, and the male rod thread (B code) bolts straight to your tooling. This unit has no magnet fitted; the optional -S code adds one for CMSE / DMSE switches. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 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 | 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 ACEJ16X20-10B Is Used
PCB fixture ejection
Ejects finished circuit boards from a test nest on an electronics line, with the 10-20 mm trimmed stroke matching shallow tray pockets.
Small-part clamping
Clamps connector housings in a CNC jig, using about 60 N of practical holding force at 0.5 MPa on the male-threaded rod.
Gate and latch actuation
Swings a short gate or latch arm on a compact packaging machine where the 50% shorter body fits inside the guarding frame.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X20-10B the Right Cylinder?
The stop screw only shortens the extend stroke as a mechanical end stop; on air loss the piston still drifts, so do not rely on it to hold a load mid-stroke. FA flange or LB foot mounts bolt to the ISO 21287 face, the port is M5x0.8 with PT body threads, and if you need position sensing order the -S version with 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 ACEJ16X20-10B FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N. At 0.7 MPa the push is 140.7 N and the pull 105.6 N. The theoretical maximum is 20.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), and speed spans 30-500 mm/s.
The -10 code sets a 10 mm adjustment window: an external stop screw shortens the 20 mm extend stroke on site, so the usable range is 10-20 mm. Fixed TPU bumpers at both ends absorb end-of-stroke energy. This version has no magnet; ordering the optional -S code adds one so CMSE or DMSE switches can be mounted on the body slots. FA flange and LB foot mounts bolt to the standard ISO 21287 face.
