Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X10-10S
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X10-10S 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 ACEJ16X10-10S
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ16X10-10S pairs a 16 mm bore with a 10 mm stroke and a 10 mm trim window. An external stop screw shortens the extend stroke on site anywhere in the 0-10 mm range, so one unit covers several fixture positions. 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 maximum of 20.5 kgf at 1.0 MPa.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which makes it easy to tuck into slim pick-and-place heads or guarded test stations. Plan on roughly 60 N (about 6 kg) of usable push at 0.5 MPa, equivalent to lifting around 5 kg vertically with a 2:1 margin. This -S version carries the optional magnet, so CMSE / DMSE reed or solid-state switches can be clipped onto the body slot for end-of-stroke signalling.

Theoretical Output Force (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 75 N |
| 0.7 MPa | 141 N | 106 N |
| Max (@1.0 MPa) | 21 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X10-10S Is Used
Micro part ejection
Ejects small stamped terminals or connector pins from a compact die, with the 0-10 mm trim window dialled in to clear the part without over-travel.
Lab sample clamping
Clamps vials or slide fixtures in benchtop testing rigs where about 60 N of usable force at 0.5 MPa is enough and panel depth is limited.
Sorted-part kick-off
Nudges classified electronic components off a sorting rail, with CMSE switches on the fitted magnet confirming each extend cycle.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X10-10S the Right Cylinder?
At 16 mm bore this sits between the 12 mm unit (56.5 N push at 0.5 MPa) and the 20 mm unit (157.1 N push at 0.5 MPa); step up if your tooling mass approaches the 6 kg usable-load mark. The stop screw is a mechanical end stop only - on air loss the piston still drifts, so do not rely on it to hold a load mid-stroke. Female M4x0.7 rod thread, PT ports, and FA flange or LB foot mounting bolt straight onto the ISO 21287 face. The fitted -S magnet enables CMSE / DMSE switch position feedback.
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 ACEJ16X10-10S FAQ
At 0.5 MPa it delivers 100.5 N push and 75.4 N pull; at 0.7 MPa, 140.7 N push and 105.6 N pull; theoretical maximum 20.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed range 30-500 mm/s with air filtered to 40 um. The 10 mm extend stroke is trimmed by the external stop screw anywhere within the ordered -10 window.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, S45C hard-chrome plated rod, threaded aluminium covers and a fixed TPU bumper at each end - about 50% shorter in mounting length than an ISO 15552 profile cylinder. The -S code on this model means the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted in the body slots. FA flange and LB foot brackets fit the standard ISO 21287 face.
