Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X35-10B
The AirTAC ACEJ12 Adjustable Compact Cylinder ACEJ16X35-10B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø16mm bore and 35mm stroke, M5×0.8 air ports and a hard-anodized aluminium body.

About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X35-10B
A double acting ISO 21287 compact cylinder, the ACEJ16X35-10B pairs a 16 mm bore with a 35 mm stroke that an external stop screw trims on site. The -10 code gives a 10 mm adjustment window, so the extend stroke can be set anywhere between 25 and 35 mm without changing the cylinder. 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 is why it slots into tight pick-and-place heads and small fixtures. The male rod thread (B code) bolts straight to tooling, and the fixed TPU bumper at both ends absorbs end-of-stroke impact. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, air filtered to 40 um.

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 ACEJ16X35-10B Is Used
Pusher on a compact inspection gate
With the optional -S magnet and a CMSE or DMSE switch, the rod position is confirmed as it sweeps rejected vials off a pharma conveyor lane within the 10 mm trim window.
Light press-fit of dowel pins
About 60 N of practical working force seats dowel pins into plastic housings on an electronics assembly jig, with the male rod thread driving the press anvil directly.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X35-10B the Right Cylinder?
The 35 mm stroke is well inside the 75 mm maximum standard stroke for this bore, so it ships as a standard item. The stop screw only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the rod can still drift if air is lost. Choose FA flange or LB foot mounting to suit the fixture, and remember the magnet is the optional -S code: this model has no magnet, so CMSE or DMSE switches cannot be fitted unless -S is ordered.
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 ACEJ16X35-10B FAQ
The 16 mm bore has an M5x0.8 port and an 8 mm rod with a male thread (B code). Operating pressure is 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, air filtered to 40 um. The -10 stop screw trims the 35 mm extend stroke by up to 10 mm, giving a 25-35 mm working range.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body and an S45C hard-chrome-plated rod, roughly 50% shorter in mounting length than an ISO 15552 profile cylinder. A fixed TPU bumper at each end absorbs end-of-stroke impact. FA flange and LB foot mountings bolt to the standard ISO 21287 face. Sensing requires the optional -S magnet - this model (no S code) carries no magnet, so CMSE or DMSE switches can only be used if you order the -S version.
