Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X45-10
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X45-10 is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø12mm bore and 45mm 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 ACEJ12X45-10
The ACEJ12X45-10 is a double acting AirTAC compact cylinder built to ISO 21287, with a 12 mm bore and 45 mm stroke that an external stop screw trims down by up to 10 mm, giving a usable extend range of 35-45 mm. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N and 59.4 N at 0.7 MPa. The hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into small fixtures and guarding where a full-length body will not fit.
Because the bore 12 rod is 6 mm with a female M3x0.5 thread, plan real work at roughly 34 N (about 0.6 of the push force), which is around 3 kg of vertical lift with a 2:1 margin. Air ports are M5x0.8, pressure runs 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and fixed TPU bumpers absorb end-of-stroke shock at both ends. No magnet is fitted; order the optional -S code if you later need CMSE or DMSE switch sensing.

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X45-10 Is Used
Micro part ejection
Trims the 45 mm stroke down to 35 mm on a small electronics feeder so delicate connectors are pushed clear without overtravel.
Light fixture clamping
The 56.5 N push at 0.5 MPa holds small PCB jigs or lens housings during a quick manual or semi-auto assembly step.
Compact slide actuation
Drives a miniature guide slide inside a tight inspection station, with CMSE or DMSE switches available once the optional -S magnet is ordered.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X45-10 the Right Cylinder?
For light clamping and positioning under about 34 N of working force, this 12 mm bore is the right size; if your load needs more, the 16 mm bore delivers 100.5 N push at 0.5 MPa, while stepping down is not possible below 12 mm in this series. Remember the stop screw only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the rod will drift if air is lost. Mounting uses FA flange or LB foot on the ISO 21287 face, and sensing requires the optional -S magnet ordered at purchase.
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 ACEJ12X45-10 FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa push is 79.2 N and pull 59.4 N; theoretical maximum is 11.5 kgf at 1.0 MPa. The ordered stroke is 45 mm and the -10 stop screw trims the extend stroke by up to 10 mm, so the working range is 35-45 mm. Ports are M5x0.8, pressure 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, S45C hard-chrome-plated 6 mm rod and fixed TPU bumpers at both ends, about 50% shorter in mounting length than an ISO 15552 profile cylinder. This model has no magnet fitted; the optional -S code adds one so CMSE or DMSE switches can be mounted. FA flange and LB foot mountings bolt to the standard ISO 21287 face.
