Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X70-10B
The AirTAC ACEJ12 Adjustable Compact Cylinder ACEJ16X70-10B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø16mm bore and 70mm 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 ACEJ16X70-10B
A double acting compact cylinder built to ISO 21287, the ACEJ16X70-10B pairs a 16 mm bore with a 70 mm stroke and a male-threaded 8 mm rod (the B code). Its short hard-anodized aluminium 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 cannot. 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.
The -10 code adds an external stop screw that trims the extend stroke by up to 10 mm on site, giving a usable range of 60-70 mm without changing the order. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the rod is S45C steel with hard-chrome plating. Note that the stop screw is a mechanical end stop only - on air loss the piston still drifts, so it is not a load-holding lock.

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 | Force (both ways) |
|---|---|
| 0.5 MPa | 75 N |
| 0.7 MPa | 106 N |
| Max (@1.0 MPa) | 15 kgf |
ACEJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X70-10B Is Used
Micro-assembly push station
Seats connectors or bearings into PCB or sensor housings on an electronics line; the male-threaded rod bolts straight to a custom pusher tip, and the short body fits inside a compact guarding frame.
Gated inspection fixture
Swings or advances a small gate in a vision-check station; with the optional -S magnet ordered, CMSE / DMSE switches report end positions along the magnet slots in the body.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X70-10B the Right Cylinder?
Both neighbors share the same M5x0.8 port. The male rod thread (B) mates directly with rod knuckles and tooling, and FA flange or LB foot mounts bolt to the ISO 21287 face. If you need position feedback, order the -S variant - this model has no magnet, so CMSE / DMSE switches cannot be fitted. Remember the adjuster only shortens the extend stroke within the 10 mm window and never holds a load on air loss.
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 ACEJ16X70-10B FAQ
Push is 100.5 N and pull 75.4 N at 0.5 MPa; at 0.7 MPa push is 140.7 N and pull 105.6 N; theoretical maximum is 20.5 kgf at 1.0 MPa. It is double acting with an adjustable extend stroke (10 mm window, so 60-70 mm usable), 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, with a M5x0.8 port and male rod thread (B code).
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA flange or LB foot mounts plus I/Y rod knuckles bolt straight to its face. Sensors are possible only if you order the optional -S magnet variant - this model has no magnet fitted, so CMSE / DMSE switches cannot be mounted on it. A fixed TPU bumper at each end absorbs end-of-stroke impact; it never locks or holds a load.
