Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X35-30B
The AirTAC ACEJ12 Adjustable Compact Cylinder ACEJ16X35-30B 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. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X35-30B
The ACEJ16X35-30B is a double acting ISO 21287 compact cylinder with a 16 mm bore and a 35 mm stroke that an external stop screw trims anywhere in a 30 mm window, giving a usable extend range of 5-35 mm. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N, rising to 140.7 N on the extend side at 0.7 MPa. Its hard-anodized aluminium body takes about 50% less mounting length than an ISO 15552 profile cylinder, so it slots into shallow fixtures and guarded cells where a full-length body cannot go.
The male rod thread (B code) bolts straight to external tooling, and the fixed TPU bumper at each end absorbs end-of-stroke impact across the 30-500 mm/s speed range.

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 ACEJ16X35-30B Is Used
Small-part ejection from jigs
The 5-35 mm adjustable extend range lets a fixture builder dial in the exact eject distance for machined aluminium brackets, with 100.5 N enough to push parts off a locating pin.
Bench-top press verification
On a light-duty test rig checking switch snap-fit force, the 16 mm bore delivers 140.7 N at 0.7 MPa and the stop screw sets a repeatable stroke for each batch.
Packaging line divert gates
A short 35 mm kick from the male-thread rod flips small cartons at a conveyor gate, and the compact body fits inside the guard where a longer profile cylinder will not.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X35-30B the Right Cylinder?
Note that the stop screw is a mechanical end stop only: on air loss the piston drifts, so it is not a load-holding device. If you need position sensing, order the -S variant to enable CMSE / DMSE switches - this model has no magnet. FA flange, LB foot and I/Y rod knuckles mount on the standard ISO 21287 face.
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 ACEJ16X35-30B 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; theoretical maximum is 20.5 kgf at 1.0 MPa. The 35 mm stroke is adjustable down to 5 mm via the 30 mm stop-screw window. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C, with an M5x0.8 port and male rod thread.
It is an ISO 21287 compact cylinder: hard-anodized aluminium body with an S45C hard-chrome-plated 8 mm rod, threaded aluminium covers, and a fixed TPU bumper at each end that only decelerates the piston at stroke ends. The body is about 50% shorter in mounting length than an ISO 15552 profile cylinder. Position sensing requires the optional -S magnet ordered with the cylinder, which then accepts CMSE / DMSE switches; without -S no magnet is fitted.
