Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X10-10B
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X10-10B 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 ACEJ16X10-10B
The ACEJ16X10-10B is a double acting ISO 21287 compact cylinder from AirTAC with an adjustable extend stroke. Its 16 mm bore delivers 100.5 N push and 75.4 N pull at 0.5 MPa, rising to 140.7 N push at 0.7 MPa, with a theoretical maximum 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 fixtures where a full-length body simply will not fit.
The -10 code gives a 10 mm adjustment window: an external stop screw trims the 10 mm extend stroke on site, giving a usable range of 0-10 mm without changing the order. For sizing, plan on roughly 60 N (about 6 kgf) of real work at 0.5 MPa, which corresponds to lifting about 5 kg vertically with a 2:1 margin. The B code supplies a male rod thread on the 8 mm rod, and the fixed TPU bumper at both ends absorbs end-of-stroke energy. Note that the magnet is not fitted here - only the optional -S code enables CMSE / DMSE switch sensing.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
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 ACEJ16X10-10B Is Used
Small-part ejection from micro moulds
The 0-10 mm trimmed stroke and 100.5 N push at 0.5 MPa eject finished clips or pins from a moulding nest without over-travel, inside a guard where a long-body cylinder cannot fit.
Presence check on electronics assembly lines
A short 10 mm probe stroke verifies a PCB or connector is seated; with the optional -S magnet, CMSE / DMSE switches confirm end positions on this compact body.
Light clamping in test fixtures
About 60 N of usable force at 0.5 MPa holds small housings during a leak or functional test, and the stop screw lets technicians fine-trim clamp travel on the bench.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X10-10B 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), so pick the 20 mm if your load needs more than about 60 N of usable force. The stop screw is a mechanical end stop for the extend stroke only - on air loss the piston still drifts, so it is not a load-holding lock. FA flange or LB foot mounts bolt to the ISO 21287 face, and if position feedback matters later, order the -S variant so CMSE / DMSE switches can be fitted.
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 ACEJ16X10-10B FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa it pushes 140.7 N and pulls 105.6 N; the theoretical maximum is 20.5 kgf at 1.0 MPa. The -10 code is a 10 mm adjustment window: an external stop screw shortens the 10 mm extend stroke on site, so the usable range is 0-10 mm. It runs double acting on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), with speed 30-500 mm/s and a fixed TPU bumper at both ends.
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 hard-anodized aluminium body, an 8 mm hard-chrome S45C rod, a male rod thread (B code) and an M5x0.8 port. Sensing is not included by default: the magnet comes only with the optional -S code, which then accepts CMSE / DMSE switches. FA flange and LB foot mounts bolt straight to the standard face.
