Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-10
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-10 is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø12mm 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 ACEJ12X30-10
A double acting compact cylinder built to ISO 21287, the ACEJ12X30-10 pairs a 12 mm bore with a 30 mm stroke and a 10 mm adjustment window. An external stop screw trims the extend stroke on site anywhere from 20 to 30 mm, so one cylinder covers several fixture positions. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N at 0.7 MPa, with a theoretical ceiling of 11.5 kgf at 1.0 MPa.
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into slim pick-and-place heads and small test rigs. Plan for roughly 34 N of real work at 0.5 MPa, about 3 kg of vertical lift with a 2:1 margin. The hard-anodized aluminium body carries a hard-chrome plated S45C rod, fixed TPU bumpers absorb end-of-stroke shock, and the optional -S magnet enables CMSE / DMSE switches when ordered.

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-10 Is Used
Lab sample ejector
The 56.5 N push at 0.5 MPa ejects microplate or vial samples, and the 20-30 mm trimmed stroke matches shallow nest depths.
Small-part press fit
About 34 N of usable force seats pins and bushings in electronics assemblies where a full-length cylinder will not fit.
Sorting gate actuator
With the optional -S magnet, CMSE / DMSE switches confirm gate position on compact conveyor diverters at 30-500 mm/s.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-10 the Right Cylinder?
At this bore size the neighbours matter: the 16 mm ACEJ16X30-10 delivers 100.5 N push at 0.5 MPa if you need nearly double the force, while stepping down is not possible since 12 mm is the smallest ACEJ bore. Match the load to about 34 N of usable push at 0.5 MPa rather than the full 56.5 N rating. FA flange or LB foot mounts bolt to the ISO 21287 face, and the female M3x0.5 rod thread takes standard tooling plates. If position feedback is needed, order the -S code; without it no magnet is fitted and no CMSE / DMSE switch will read.
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 ACEJ12X30-10 FAQ
Push is 56.5 N and pull 42.4 N at 0.5 MPa; at 0.7 MPa it reaches 79.2 N push and 59.4 N pull, with a theoretical maximum of 11.5 kgf at 1.0 MPa. It runs 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. The extend stroke is adjustable from 20 to 30 mm via the external stop screw, and the M5x0.8 port depends only on the 12 mm bore.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA flange and LB foot options on the standard face. A fixed TPU bumper at each end absorbs end-of-stroke impact. Sensing requires the optional -S magnet code; this model has no magnet fitted, so CMSE / DMSE switches only work if -S was ordered.
