About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X15-10B
The ACEJ12X15-10B is a double acting compact cylinder built to ISO 21287, with a 12 mm bore and a 15 mm stroke that an external stop screw trims anywhere in a 10 mm window, giving a usable extend range of 5-15 mm. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa those figures rise to 79.2 N and 59.4 N, with a theoretical ceiling of 11.5 kgf at 1.0 MPa. Air runs at 0.15-1.0 MPa (22-145 psi) and rod speed from 30-500 mm/s.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim pick-and-place heads and micro fixtures. The male-threaded rod (B code) bolts directly to tooling, and the hard-anodized aluminium body with an S45C hard-chrome rod stands up to millions of short cycles.

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 (Ø12mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 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 ACEJ12X15-10B Is Used
Micro part ejection
Ejects small machined or molded parts from a nest with a short, repeatable push; the 5-15 mm trimmed range matches shallow cavities without overtravel.
Light snap-fit press
Presses battery covers or connector clips home with about 34 N of usable force at 0.5 MPa, enough for plastic snap features without damaging the housing.
Compact gating on test rigs
Swings or blocks a small gate inside a tight test fixture; the short body fits where an ISO 15552 profile cylinder would be twice as long.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X15-10B the Right Cylinder?
The stop screw shortens the extend stroke only - it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. No magnet is fitted on this code; order the -S variant if CMSE / DMSE switches are needed later. PT ports, male rod thread, FA flange or LB foot mounting.
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 ACEJ12X15-10B FAQ
Operating pressure is 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, air filtered to 40 um. The extend stroke is trimmed by a stop screw within the 10 mm window (5-15 mm usable), and a fixed TPU bumper sits at both ends.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, threaded aluminium covers, an S45C hard-chrome plated 6 mm rod and a male rod thread on this B-code model. The body is about 50% shorter in mounting length than an ISO 15552 profile cylinder. Sensing requires the optional -S magnet code with CMSE or DMSE switches; this unit has no magnet fitted, so no switch can be read on it as ordered.
