About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-40S
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ80X120-40S pairs an 80 mm bore with a 120 mm stroke and a 40 mm trim window. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa, so it has the muscle for heavy clamping and pressing. The hard-anodized aluminium body with an S45C hard-chrome rod runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um at 30-500 mm/s.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, letting this 80 mm bore sit inside press frames and weld fixtures where a full-length body will not reach. The fitted -S magnet accepts CMSE / DMSE switches, and a fixed TPU bumper at each end absorbs end-of-stroke shock.

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 (Ø80mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 2356 N |
| 0.7 MPa | 3299 N |
| Max (@1.0 MPa) | 481 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 ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-40S Is Used
Pallet lift-and-push station
With about 153 kg of vertical lift equivalent at 0.5 MPa (halved for margin), the 80 mm bore raises and indexes loaded pallets on warehouse transfer lines.
Weld fixture ejector
The short ISO 21287 body fits inside tight weld-cell tooling, while the fitted magnet and CMSE switches confirm rod position to the PLC at each cycle.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-40S the Right Cylinder?
The -40 stop screw trims the extend stroke anywhere in an 80-120 mm range on site; it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA flange and LB foot mountings bolt to the ISO 21287 face, and the fitted magnet works with CMSE / DMSE switches.
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 ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-40S FAQ
Push is 2513.3 N and pull 2356.2 N at 0.5 MPa; at 0.7 MPa push reaches 3518.6 N, and theoretical maximum force is 512.6 kgf at 1.0 MPa. It is double acting with an adjustable extend stroke: the stop screw trims the 120 mm stroke by up to 40 mm, giving an 80-120 mm working range. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, air filtered to 40 um, with a 1/8" port and M12x1.75 female rod thread.
It is an ISO 21287 compact cylinder - about 50% shorter in mounting length than an ISO 15552 profile cylinder - with a hard-anodized aluminium body, S45C hard-chrome rod and threaded aluminium covers. Fixed TPU bumpers at both ends absorb end-of-stroke energy. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount in the body slots; FA flange and LB foot brackets bolt straight to the standard face.
