Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X75-20S
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X75-20S is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø16mm bore and 75mm 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 ACEJ16X75-20S
A double acting ISO 21287 compact cylinder, the ACEJ16X75-20S pairs a 16 mm bore with a 75 mm stroke and a 20 mm adjustment window: an external stop screw trims the extend stroke anywhere in the 55-75 mm range without changing parts. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N, rising to 140.7 N at 0.7 MPa. In practice that means about 60 N of usable work at 0.5 MPa, or roughly 5 kg lifted vertically with a 2:1 margin - enough for small clamps, gates and light pick-and-place heads.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures and guarded cells. The hard-anodized aluminium barrel carries an S45C hard-chrome rod, fixed TPU bumpers absorb end-of-stroke shock, and because the -20S code includes the optional magnet, CMSE / DMSE reed or solid-state switches can be fitted anywhere along the body for end-of-travel 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 ACEJ16X75-20S Is Used
Small-part ejection in plastic moulding
A 100.5 N push at 0.5 MPa is enough to kick finished caps or bushings off a mould table, and the 55-75 mm trim lets one cylinder serve several shallow mould depths.
Position-confirmed gating on conveyor lines
With the -20S magnet fitted, CMSE or DMSE switches confirm gate open and closed on sorting chutes, while the compact body fits between tight conveyor frames.
Sample press in lab automation
About 5 kg of vertical lift capacity with a 2:1 margin suits pressing microplates or lids in diagnostic analysers where panel space is scarce.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X75-20S the Right Cylinder?
Size this bore when your load sits under about 60 N at 0.5 MPa. If you need more, the 20 mm bore delivers 157.1 N push at 0.5 MPa; if less force and a smaller envelope suffice, the 12 mm bore gives 56.5 N. Both neighbours share the same M5x0.8 port and ISO 21287 mounting face. Remember the stop screw only shortens the extend stroke - it is not a mid-stroke lock, so on air loss the rod can still drift under load. Bolt on FA flange or LB foot brackets, and specify the B male-thread rod variant if your tooling needs a stud instead of the standard M4x0.7 female thread.
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 ACEJ16X75-20S FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa, 140.7 N push and 105.6 N pull; theoretical maximum is 20.5 kgf at 1.0 MPa. The -20 code gives a 20 mm adjustment window: an external stop screw shortens the 75 mm extend stroke down to 55 mm. It is a mechanical end stop only - it never holds a load if air is lost. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, -20 to +70 C.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits slim jigs and guarded machines. This -20S model carries the optional magnet, so CMSE / DMSE reed or solid-state switches mount in the body slots for end-of-travel signals. FA flange and LB foot brackets bolt to the standard face, and the rod ends in an M4x0.7 female thread.
