Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X60-40B
The AirTAC ACEJ12 Adjustable Compact Cylinder ACEJ16X60-40B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø16mm bore and 60mm 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 ACEJ16X60-40B
The ACEJ16X60-40B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 60 mm stroke by up to 40 mm, giving a usable range of 20-60 mm on site. Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into tight fixtures where a full-length body cannot.
The hard-anodized aluminium body carries an S45C hard-chrome plated 8 mm rod with a male thread (the B code), and a fixed TPU bumper at each end absorbs end-of-stroke energy. Note the stop screw is a mechanical end stop only - on air loss the piston still drifts, so it is not a load-holding lock.

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 ACEJ16X60-40B Is Used
Small-part press fitting
Presses dowel pins or bushings into aluminium housings on an electronics assembly bench, where the 20-60 mm adjustable window lets one cylinder serve several part heights.
Compact gating on packaging lines
Kicks small cartons or blisters between conveyor lanes inside a tight guard, using the short ISO 21287 body to save mounting length.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X60-40B the Right Cylinder?
The male rod thread suits external rod couplings and knuckles, and FA flange or LB foot mounts bolt to the standard ISO 21287 face. If you need position sensing, order the -S variant - this model has no magnet, so CMSE / DMSE switches cannot be fitted. Max standard stroke for bore 16 is 75 mm, so the 60 mm stroke is a standard build.
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 ACEJ16X60-40B 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 8 mm male-thread rod, an M5x0.8 port, and the -40 stop screw trims the 60 mm extend stroke down to 20 mm. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a fixed TPU bumper at both ends.
An external stop screw shortens the extend stroke within the ordered 40 mm window, so the working range is 20-60 mm; it is a mechanical end stop, not a mid-stroke lock, and the piston still drifts if air is lost. This model has no magnet, so no CMSE or DMSE switch can be mounted - order the -S code instead to get the optional magnet and enable position sensing. FA flange and LB foot mounts bolt straight to the ISO 21287 face.
