About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X100-40
A double acting ISO 21287 compact cylinder, the ACEJ80X100-40 pairs an 80 mm bore with a 100 mm stroke that an external stop screw can trim by up to 40 mm on site, giving a usable extend range of 60-100 mm. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa those figures rise to 3518.6 N and 3298.7 N, with a theoretical ceiling of 512.6 kgf at 1.0 MPa. As a working rule, plan on roughly 1508 N (about 153 kg) of real pushing effort at 0.5 MPa rather than the full rating.
The hard-anodized aluminium body with an S45C hard-chrome plated 20 mm rod 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. A fixed TPU bumper at each end absorbs end-of-stroke shock, speed runs 30-500 mm/s, and the 1/8" port matches the 80 mm bore. Note that the stop screw is a mechanical end stop only: on air loss the piston still drifts, so it is not a load lock.

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 ACEJ80X100-40 Is Used
Bench-top crimping and staking
With about 153 kg of practical push at 0.5 MPa, the 80 mm bore suits light crimp, stake and swage stations on electronics and small assembly lines, with the 40 mm window letting one cylinder serve several part heights.
Fixture clamping on machining centres
The short ISO 21287 body mounts inside tight jig frames where an ISO 15552 profile cylinder is too long, and FA flange mounting drops straight onto standard fixture plates.
Short-stroke press and ejection stations
Trim the extend stroke between 60 and 100 mm to match die or ejector travel on packaging and assembly machinery, with the TPU bumpers softening both ends at speeds up to 500 mm/s.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X100-40 the Right Cylinder?
If your fixture needs a mid-range trim rather than a fixed end position, the 40 mm window (60-100 mm usable stroke) is the reason to pick this code over a plain ACE. FA flange or LB foot mounts bolt to the ISO 21287 face, and rod knuckles I and Y are available. If you need position detection, order the -S variant: without the S code there is no magnet and no CMSE / DMSE switch can be read.
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 ACEJ80X100-40 FAQ
The -40 code sets a 40 mm adjustment window: an external stop screw shortens the 100 mm extend stroke by up to 40 mm, so the usable range is 60-100 mm. It shortens the stroke only - it never extends it past 100 mm - and it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, a hard-chrome plated S45C 20 mm rod, threaded aluminium covers and a fixed TPU bumper at both ends. The body is about 50% shorter in mounting length than an ISO 15552 profile cylinder. Ports are 1/8" (PT thread), the rod end is female M12x1.75, operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, temperature -20 to +70 C, speed 30-500 mm/s on air filtered to 40 um. Position sensing requires the optional -S magnet code; this model has no magnet, so CMSE / DMSE switches cannot be fitted unless you order the S variant. Mounting: FA flange, LB foot, plus I and Y rod knuckles.
