About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X75-50B
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ80X75-50B pairs an 80 mm bore with a 75 mm stroke and a male rod thread (B code). The external stop screw trims the extend stroke anywhere within the ordered 50 mm window, giving a usable range of 25-75 mm without changing hardware.
The hard-anodized aluminium body with an S45C hard-chrome plated 20 mm rod runs at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s, with a fixed TPU bumper at each end. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits guarded gantries and tight press fixtures. FA flange and LB foot mounts bolt straight to the ISO 21287 face.

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 ACEJ80X75-50B Is Used
Gantry pick-and-place
Mounted under a packaging-line gantry, the short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, pressing cartons closed in the space above the conveyor guard.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X75-50B the Right Cylinder?
Remember the stop screw is a mechanical end stop for the extend stroke only - on air loss the piston still drifts, so do not rely on it to hold a load mid-stroke. This unit has no magnet fitted; if you need CMSE or DMSE switches for end-position sensing, order the -S version. PT ports take standard fittings, and the male rod thread suits clevis-style linkages.
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 ACEJ80X75-50B 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 -50 code is a 50 mm adjustment window: an external stop screw shortens the 75 mm extend stroke by up to 50 mm, so the usable range is 25-75 mm. It shortens the stroke only - it never extends past 75 mm - and it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost.
It is an ISO 21287 compact cylinder whose 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 a fixed TPU bumper at both ends. Position sensing requires the optional -S magnet code - this unit has no magnet, so no switch can be mounted unless you order it; with -S, CMSE and DMSE switches track the piston. FA flange and LB foot mounts bolt straight to the ISO 21287 face, and the male rod thread (B) suits knuckle linkages.
