About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X60-20B
A double acting ISO 21287 compact cylinder, the ACEJ16X60-20B pairs a 16 mm bore with a 60 mm stroke that an external stop screw trims on site within the ordered 20 mm window, giving a usable extend range of 40-60 mm. 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. Air supply is 0.15-1.0 MPa (22-145 psi) filtered to 40 um, rod speed 30-500 mm/s, and a fixed TPU bumper sits at each end of travel.
The hard-anodized aluminium body and S45C hard-chrome-plated 8 mm rod keep the short frame rigid, and the body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slides into tight jigs and guarded assemblies. The B code gives a male rod thread, and the optional -S magnet enables CMSE / DMSE switches when position feedback is needed.

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 ACEJ16X60-20B Is Used
Small-part press fitting
Presses dowel pins or bushings into aluminium housings on electronics assembly benches, where the 40-60 mm adjustable range matches varied part heights without swapping cylinders.
Fixture clamping in tight cells
Clamps machined brackets inside compact jigs, the short body fitting where an ISO 15552 profile cylinder of equal stroke would not clear the fixture wall.
Lab and test station actuation
Drives small test heads and sample holders at 30-500 mm/s on benchtop rigs, with the male rod thread taking a knuckle for pivoting probes.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X60-20B the Right Cylinder?
Size this bore when your load sits near 60 N of working force at 0.5 MPa. The stop screw only shortens the extend stroke and 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 male rod thread suits knuckle accessories ordered with I or Y codes. If you need switch feedback, order the -S variant; this model has no magnet fitted.
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 ACEJ16X60-20B FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa it pushes 140.7 N and pulls 105.6 N, with a theoretical maximum of 20.5 kgf at 1.0 MPa. The -20 code sets a 20 mm adjustment window: an external stop screw shortens the 60 mm extend stroke by up to 20 mm, so the working range is 40-60 mm. It shortens the stroke only and acts as an end stop, not a load-holding brake. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, an 8 mm hard-chrome-plated rod, and fixed TPU bumpers at both ends. FA flange and LB foot mounts bolt straight to the standard face. Position sensing requires the optional -S magnet code; this model has no magnet, so no CMSE or DMSE switch can be read on it as ordered.
