About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X75-20B
The ACEJ80X75-20B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 75 mm stroke by up to 20 mm on site, giving a usable range of 55-75 mm.
The hard-anodized aluminium body carries an S45C hard-chrome plated 20 mm rod, a fixed TPU bumper absorbs end-of-stroke energy at both ends, and the male rod thread (B code) bolts straight into standard tooling. Speed range is 30-500 mm/s across 0.15-1.0 MPa (22-145 psi).

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 ACEJ80X75-20B Is Used
Pallet gate actuation
Swings heavy pallet-line gates and stops where the short ISO 21287 body fits inside the conveyor frame that a full-length profile cylinder cannot.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X75-20B the Right Cylinder?
Note the stop screw is a mechanical end stop for the extend stroke only - it does not lock the piston mid-stroke, and on air loss the rod can drift. Mount with FA flange or LB foot on the ISO 21287 face; if position feedback is needed later, order the -S variant, since this model has no magnet and no CMSE / DMSE switch can be 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 ACEJ80X75-20B FAQ
Push is 2513.3 N and pull 2356.2 N at 0.5 MPa; at 0.7 MPa push reaches 3518.6 N (pull 3298.7 N), with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -20 code sets a 20 mm adjustment window: the external stop screw shortens the 75 mm extend stroke to any length down to 55 mm. It runs double acting on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, with a 1/8" PT port and a 20 mm male-thread rod.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight machine frames. A fixed TPU bumper at each end absorbs end-of-stroke impact. FA flange and LB foot mount to the standard face. This model ships without a magnet, so no switch can be read from it - order the -S code to enable CMSE / DMSE switches.
