About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-30S
A double acting ISO 21287 compact cylinder, the ACEJ80X120-30S pairs an 80 mm bore with a 120 mm stroke that an external stop screw trims by up to 30 mm on site, giving a usable extend range of 90-120 mm. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, gantries and guarding where a full-length body will not fit.
The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod with a female M12x1.75 thread, and 1/8" ports feed air at 0.15-1.0 MPa (22-145 psi) with speeds of 30-500 mm/s. Because the -S magnet is fitted, CMSE / DMSE reed or solid-state switches mount directly in the body slots for end-of-travel sensing. A fixed TPU bumper at each end absorbs end-of-stroke energy; it is a stop pad, not a load lock, so the rod can drift if air is lost.

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 ACEJ80X120-30S Is Used
Injection mould fixture clamping
Foot-mounted (LB) units clamp mould inserts and gate trim fixtures, with CMSE switches on the fitted magnet confirming full clamp before the machine cycle releases.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-30S the Right Cylinder?
The stop screw shortens the extend stroke only - it never extends beyond 120 mm and does not hold a load mid-stroke. FA flange and LB foot mountings bolt to the ISO 21287 face, and I or Y rod knuckles suit the female M12x1.75 thread. The fitted -S magnet accepts CMSE / DMSE switches; order PT or G port thread to match your fittings.
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 ACEJ80X120-30S FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push is 3518.6 N and pull 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -30 code is a 30 mm adjustment window: an external stop screw shortens the 120 mm extend stroke to any setting from 90 to 120 mm. It is a mechanical end stop only - on air loss the piston drifts, so it is not a load-holding brake.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, 20 mm hard-chrome rod, female M12x1.75 rod thread, 1/8" ports and a fixed TPU bumper at both ends. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots; FA flange and LB foot mountings plus I/Y rod knuckles bolt straight on.
