About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X75-40
The ACEJ16X75-40 is a double acting AirTAC compact cylinder built to ISO 21287, with a 16 mm bore and a 75 mm stroke that can be trimmed on site by up to 40 mm. An external stop screw shortens the extend stroke anywhere in the 35-75 mm range, so one unit covers several jig positions without swapping cylinders. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa those 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 suits slim guarding and tight gantry frames. As a rule of thumb, plan on roughly 60 N of real work at 0.5 MPa (about 0.6 of the push force), which lifts about 5 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers sit at both ends, and speed spans 30-500 mm/s. Note that this code has no magnet: order the optional -S version if you need CMSE or DMSE switch sensing.

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X75-40 Is Used
Small-part ejection from plastic molds
The 100.5 N push at 0.5 MPa ejects caps and clips from shallow cavities, and the 35-75 mm adjustable window lets one cylinder serve several mold sizes.
Stopper stations on electronics assembly benches
A 75 mm stroke presents PCB trays to an operator, and with the optional -S magnet a CMSE or DMSE switch confirms the extend position.
Light press-fit of bushings and dowels
About 60 N of usable force at 0.5 MPa presses small bushings into housings, while the compact body fits inside a benchtop fixture frame.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X75-40 the Right Cylinder?
At 100.5 N push at 0.5 MPa this 16 mm bore suits light clamping and part-presenting duty. Step down to a 12 mm bore (56.5 N push at 0.5 MPa) for lighter eject tasks, or up to a 20 mm bore (157.1 N push at 0.5 MPa) when the load grows. The stop screw is a mechanical end stop for the extend stroke only, not a mid-stroke lock: on air loss the piston can still drift, so do not rely on it to hold a load. FA flange or LB foot mounts bolt to the ISO 21287 face, and the female M4x0.7 rod thread accepts standard knuckles. Remember the magnet is only present when the -S code 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 ACEJ16X75-40 FAQ
Push is 100.5 N and pull is 75.4 N at 0.5 MPa; at 0.7 MPa push reaches 140.7 N and pull 105.6 N, with a theoretical maximum of 20.5 kgf at 1.0 MPa. The 75 mm extend stroke is trimmed by an external stop screw anywhere within the 40 mm window, giving a usable range of 35-75 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the port is M5x0.8 with a female M4x0.7 rod thread.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits slim guards and tight fixtures. Fixed TPU bumpers at both ends absorb end-of-stroke energy. Sensing requires the optional -S magnet: with it, CMSE or DMSE switches mount in the body slots; this standard code has no magnet, so no switch can be read. FA flange and LB foot mounts bolt straight to the ISO 21287 face.
