About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X55-10
The ACEJ16X55-10 is a double acting ISO 21287 compact cylinder with a 16 mm bore and a 55 mm stroke that an external stop screw can trim by up to 10 mm, giving a usable extend range of 45-55 mm. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N, rising to 140.7 N at 0.7 MPa, with a theoretical ceiling of 20.5 kgf at 1.0 MPa. Plan on roughly 60 N of real work at 0.5 MPa, which is about 6 kg of vertical lift with a 2:1 margin - enough for small clamps, gates and light pick-and-place parts.
The short ISO 21287 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 will not fit. A hard-anodized aluminium barrel carries an S45C hard-chrome rod with a female M4x0.7 thread, fixed TPU bumpers sit at both ends, and the piston seal stores grease for long service. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi). Note there is no magnet fitted on this version; order the -S code if you later need CMSE / DMSE switch position sensing.

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 | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 75 N |
| 0.7 MPa | 141 N | 106 N |
| Max (@1.0 MPa) | 21 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X55-10 Is Used
Small-part press fitting
Seating bushings or dowel pins into plastic housings on an electronics assembly bench, where the 100.5 N push at 0.5 MPa and a trimmed 45-55 mm stroke match shallow press depths.
Light clamp fixtures
Holding thin aluminium sheet or PCB panels against a drill jig; the compact body fits inside the jig frame, and the stop screw sets exact clamp position per part.
Ejector on packaging chutes
Kicking small cartons or blister packs off a conveyor lane; at about 5 kg of safe vertical lift capacity it handles lightweight product only, at 30-500 mm/s.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X55-10 the Right Cylinder?
Size against neighbours: the 12 mm bore gives only 56.5 N push at 0.5 MPa, while the 20 mm bore reaches 157.1 N - pick this 16 mm model when your load sits between about 40 and 60 N working force. The stop screw shortens the extend stroke only; it never lengthens it past 55 mm, and it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA flange or LB foot mounts bolt to the ISO 21287 face, and the female M4x0.7 rod thread takes standard knuckles. Air supply must be filtered to 40 um.
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 ACEJ16X55-10 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, with a theoretical maximum of 20.5 kgf at 1.0 MPa. The -10 code sets a 10 mm adjustment window: an external stop screw shortens the 55 mm extend stroke anywhere down to 45 mm. It is a mechanical end stop for the extend direction only - on air loss the piston can still drift, so it is not a load-holding lock. 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, and the port is M5x0.8.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guarded machines. It has a hard-anodized aluminium barrel, an S45C hard-chrome rod with female M4x0.7 thread, and fixed TPU bumpers at both ends. Switches are not possible on this version as ordered: the magnet is the optional -S code, so specify ACEJ16X55-10S if you want CMSE or DMSE sensors. FA flange and LB foot mounts fit the standard ISO 21287 face.
