Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X10-10
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X10-10 is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø16mm bore and 10mm 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 ACEJ16X10-10
A double acting compact actuator built to ISO 21287, the ACEJ16X10-10 pairs a 16 mm bore with a 10 mm stroke and an external stop screw that trims the extend stroke anywhere in a 0-10 mm window on site. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N, rising to 140.7 N at 0.7 MPa, with a theoretical peak of 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 slim pick-and-place heads and micro fixtures.
The hard-anodized aluminium body carries an S45C hard-chrome plated 8 mm rod with a female M4x0.7 thread, and a fixed TPU bumper at each end absorbs end-of-stroke impact. Plan on roughly 60 N of usable push at 0.5 MPa, which is about 5 kg of vertical lift with a 2:1 margin. Air ports are M5x0.8, speed runs 30-500 mm/s, and the optional -S magnet code enables CMSE / DMSE switches; without -S no magnet is fitted.

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X10-10 Is Used
Micro part ejection
Taps tiny machined or molded parts off a nest with a short 0-10 mm trimmed push, using about 60 N of usable force at 0.5 MPa.
Small fixture clamping
Clamps circuit boards or small brackets in test jigs where the compact body fits inside the fixture frame and 100.5 N of push is enough.
Sorted-bin diverting
With the optional -S magnet and a CMSE switch, confirms end position when nudging small components between two lanes on a benchtop sorter.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X10-10 the Right Cylinder?
For a 10 mm trim task needing near 100 N, bore 16 fits; bore 12 gives 56.5 N push at 0.5 MPa if the load is lighter, while bore 20 delivers 157.1 N for heavier clamps. The stop screw is a mechanical end stop only - on air loss the piston drifts, so it is not a load-holding lock. Order FA or LB mounting to match the fixture, and add the -S code if CMSE / DMSE position sensing is needed.
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 ACEJ16X10-10 FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa push is 140.7 N and pull 105.6 N; theoretical maximum is 20.5 kgf at 1.0 MPa. The -10 code sets a 10 mm adjustment window: an external stop screw shortens the 10 mm extend stroke on site, giving a usable range of 0-10 mm. It is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends and FA or LB mounting options. Position sensing requires the optional -S magnet code, which allows CMSE / DMSE switches; without -S there is no magnet and no switch can be read. Air supply is 0.15-1.0 MPa (22-145 psi) filtered to 40 um, speed 30-500 mm/s.
