About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X45-40
A double acting ISO 21287 compact cylinder, the ACEJ80X45-40 pairs an 80 mm bore with a 45 mm stroke and an external stop screw that trims the extend stroke anywhere within the ordered 40 mm window, giving a usable range of 5-45 mm on site. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa those rise to 3518.6 N and 3298.7 N, with a theoretical ceiling of 512.6 kgf at 1.0 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight clamping fixtures and machine frames where a full-length body simply will not fit.
The hard-anodized aluminium body carries a roller-burnished bore, the S45C rod is hard-chrome plated, and a fixed TPU bumper at each end absorbs end-of-stroke energy. Air supply is 0.15-1.0 MPa (22-145 psi), speed runs 30-500 mm/s, and the rod ends in a female M12x1.75 thread with 1/8" ports.

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 ACEJ80X45-40 Is Used
Press-fit bushings into gearbox housings
With about 1508 N of practical force at 0.5 MPa, the 80 mm bore handles light press-fit assembly of bearings and bushings, and the 5-45 mm trim range lets you dial the stroke to each housing depth.
Lifting gate panels on a packaging machine
Halving the vertical capacity gives about 128 kg of lift margin, enough to raise heavy guard or gate panels, with the TPU bumper softening each end of the short 45 mm travel.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X45-40 the Right Cylinder?
If your clamping or pressing load needs more than about 1508 N of practical force, this bore is the right call. Remember the stop screw is a mechanical end stop only - on air loss the piston drifts, so add a separate valve or lock if position must be held. FA flange or LB foot mountings bolt to the ISO 21287 face, and if you need position sensing, order the -S variant so CMSE / DMSE switches can be used; this unit has no magnet fitted.
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 ACEJ80X45-40 FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa it pushes 3518.6 N and pulls 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -40 code sets a 40 mm adjustment window: an external stop screw shortens the 45 mm extend stroke by up to 40 mm, so the working range is 5-45 mm. It runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um at 30-500 mm/s, with a female M12x1.75 rod thread and 1/8" ports.
It is an ISO 21287 compact cylinder whose hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends to absorb end-of-stroke impact. FA flange and LB foot mountings bolt straight to the standard face. Position sensing requires the optional -S magnet code - this model has no magnet fitted, so CMSE or DMSE switches can only be used on an -S ordered unit.
