About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X70-10SB
The ACEJ16X70-10SB is a double acting AirTAC compact cylinder built to ISO 21287, with a 16 mm bore and a 70 mm extend stroke that an external stop screw can trim by up to 10 mm on site, giving a usable range of 60-70 mm. At 0.5 MPa it pushes with 100.5 N and pulls with 75.4 N; at 0.7 MPa those rise to 140.7 N and 105.6 N. The hard-anodized aluminium body and S45C hard-chrome plated rod suit light clamping and positioning duty at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s.
Its short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures and guarded cells. The -S code on this model means the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted anywhere along the body slots, and the B code gives a male 8 mm rod thread.

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 ACEJ16X70-10SB Is Used
Bottle stopper press in a lab filler
A 16 mm bore pressing stoppers into vials benefits from the short body that fits inside a compact guarding frame, while the fitted magnet feeds stopper-seated signals to the PLC via a CMSE switch.
Carton flap tuck on a packaging line
At 30-500 mm/s the cylinder tucks flaps on small cartons; the male rod thread (B code) takes a knuckle or custom pad, and the 10 mm stop screw absorbs flap-thickness variation.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X70-10SB the Right Cylinder?
The 10 mm adjustment window suits jigs where the final clamp position is tuned during commissioning. Remember the stop screw is a mechanical end stop only - on air loss the piston drifts, so it is not a load-holding brake. FA flange or LB foot mountings bolt to the ISO 21287 face, and the fitted magnet pairs with CMSE / DMSE switches for end-of-stroke signals.
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 ACEJ16X70-10SB 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 16 mm bore has an M5x0.8 port, an 8 mm male rod thread (B code) and a PT port thread. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-500 mm/s, air filtered to 40 um. The stop screw trims the 70 mm extend stroke by up to 10 mm (60-70 mm usable).
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight jigs and guarded machines. A fixed TPU bumper at each end absorbs end-of-stroke energy. Because the -S magnet is fitted on this model, CMSE / DMSE reed or solid-state switches mount in the body slots for position signals. FA flange, LB foot and rod knuckles attach to the standard ISO 21287 face.
