Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X55-40B
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X55-40B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 55mm stroke, 1/8" air ports and a hard-anodized aluminium body.

About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X55-40B
A double acting ISO 21287 compact cylinder, the ACEJ80X55-40B pairs an 80 mm bore with a 55 mm stroke and a male-threaded 20 mm rod. 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 carries the heavy clamping and press-fit work in a short-body format. The external stop screw trims the extend stroke anywhere inside the ordered 40 mm window, giving a usable range of 15-55 mm without changing hardware.
The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a heavy-duty cylinder must fit inside a weld cell guard or a low gantry beam. Fixed TPU bumpers absorb end-of-stroke shock, speed runs 30-500 mm/s, and the optional -S magnet enables CMSE / DMSE switches.

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 ACEJ80X55-40B Is Used
Heavy weld-fixture clamping
With about 1508 N of usable clamp force at 0.5 MPa, it holds steel brackets through weld cycles inside guards where a full-length profile cylinder will not fit.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X55-40B the Right Cylinder?
The stop screw shortens the extend stroke only; it never lengthens it past 55 mm, and it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost. Mount with FA flange or LB foot on the ISO 21287 face, add I or Y rod knuckles for side misalignment, and order the -S code if CMSE / DMSE position sensing is planned.
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 ACEJ80X55-40B 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 -40 code is a 40 mm adjustment window: an external stop screw shortens the 55 mm extend stroke on site, giving a usable range of 15-55 mm. It shortens the stroke only and acts as a mechanical end stop, not a mid-stroke lock, so the piston still drifts on air loss. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome 20 mm rod, 1/8" PT ports and fixed TPU bumpers at both ends. FA flange, LB foot, FTC brackets and I/Y rod knuckles bolt to the standard face. Position sensing needs the optional -S magnet code; without it no magnet is fitted, so CMSE / DMSE switches cannot be mounted.
