Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X15-10S
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X15-10S is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø16mm bore and 15mm 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 ACEJ16X15-10S
A double acting ISO 21287 compact cylinder with a tunable extend stroke, the ACEJ16X15-10S pairs a 16 mm bore with a 15 mm stroke that an external stop screw trims anywhere within the ordered 10 mm window, giving a usable range of 5-15 mm. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N, rising to 140.7 N at 0.7 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures where a full-length body cannot.
This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped onto the body for end-of-stroke signalling. In practice, plan on roughly 60 N (about 6 kgf) of usable push at 0.5 MPa, which corresponds to lifting about 5 kg vertically with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the hard-anodized aluminium body with an S45C hard-chrome plated 8 mm rod stands up to continuous cycling.

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 ACEJ16X15-10S Is Used
Small-part ejection from jigs
A 100.5 N push at 0.5 MPa is enough to eject machined bushings or plastic caps from a drill jig, and the 5-15 mm adjustable range lets you match the ejector pin travel exactly.
Indexed fixture clamping with proof
With the -S magnet fitted, CMSE or DMSE switches confirm the clamp has reached its trimmed position on a rotary indexing table, closing the loop on short-stroke clamping of electronics housings.
Bottle-capping press head
The compact short body fits inside a benchtop capping or labelling head where an ISO 15552 profile cylinder would be twice as long, pressing closures onto cosmetic or pharmaceutical vials.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X15-10S the Right Cylinder?
Size by force: the 12 mm bore delivers 56.5 N push at 0.5 MPa, while stepping up to the 20 mm bore raises it to 157.1 N - choose this 16 mm model when your load sits between those figures and you need a 5-15 mm extend range. Remember the stop screw sets the extend end position only; it is not a mid-stroke lock, so the rod still drifts if air is lost. FA flange, LB foot and FTC brackets bolt to the ISO 21287 face, and I/Y rod knuckles suit the M4x0.7 female rod thread. Order the -S code (as here) whenever 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 ACEJ16X15-10S 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, with a theoretical maximum of 20.5 kgf at 1.0 MPa. The -10 code is a 10 mm adjustment window: an external stop screw shortens the 15 mm extend stroke on site, so the usable range is 5-15 mm. 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.
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 to absorb end-of-stroke energy. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount in the body slots. FA flange, LB foot and FTC brackets plus I/Y rod knuckles attach to the standard ISO 21287 face, and the rod end is a female M4x0.7 thread with an M5x0.8 air port.
