Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X60-40SB
The AirTAC ACEJ12 Adjustable Compact Cylinder ACEJ16X60-40SB 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 ACEJ16X60-40SB
This is a double acting AirTAC ACEJ compact cylinder built to ISO 21287, with a 16 mm bore and a 60 mm stroke that an external stop screw trims down by up to 40 mm, giving a usable extend range of 20-60 mm. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa those figures rise to 140.7 N and 105.6 N. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures a full-length body cannot reach.
The male rod thread (B code) suits couplings and tooling that screw straight on, and this model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be fitted for end-of-stroke signalling. A fixed TPU bumper at each end absorbs end-of-stroke impact, and the hard-anodized aluminium body with an S45C hard-chrome rod stands up to continuous cycling.

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 ACEJ16X60-40SB Is Used
Part-present ejection on assembly lines
With the fitted -S magnet driving CMSE switches, the cylinder confirms reject shots on a small-parts conveyor, while the male rod thread takes a custom ejector tip directly.
Sample tray indexing in lab automation
The short ISO 21287 body fits inside compact analyser enclosures, and the 60 mm stroke with a 40 mm trim window lets engineers fine-tune tray pitch during commissioning.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X60-40SB the Right Cylinder?
The 40 mm window means you can dial the extend stroke anywhere from 20 to 60 mm on site, which is ideal when fixture spacing is not final. Note that the stop screw is a mechanical end stop only: on air loss the piston still drifts, so it is not a mid-stroke lock. Mounting: FA flange or LB foot bolt to the ISO 21287 face, and the fitted -S magnet lets CMSE / DMSE switches report position. Speed range is 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).
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 ACEJ16X60-40SB FAQ
Bore 16 mm, stroke 60 mm adjustable down to 20 mm via the -40 stop screw. Push is 100.5 N and pull 75.4 N at 0.5 MPa; at 0.7 MPa push is 140.7 N and pull 105.6 N; theoretical maximum is 20.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, and temperature -20 to +70 C. Port is M5x0.8 and the rod end is male thread.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA flange or LB foot brackets bolt straight to its face. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped onto the body slots for end-of-stroke detection. A fixed TPU bumper at both ends absorbs impact; it is a deceleration pad only and never holds or brakes a load.
