About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X300-75
A double acting AirTAC compact cylinder built to ISO 21287, the ACEJ80X300-75 pairs an 80 mm bore with a 300 mm stroke and an external stop screw that trims the extend stroke by up to 75 mm on site, giving a usable range of 225-300 mm. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa, with a theoretical peak of 512.6 kgf at 1.0 MPa. The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod and a female M12x1.75 rod thread; air ports are 1/8" PT.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, gantries and fixture plates where a full-length body will not fit. FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to the ISO 21287 face. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi); a fixed TPU bumper sits at both ends. The magnet is not fitted - order the optional -S code if you need CMSE / DMSE switch sensing.

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 ACEJ80X300-75 Is Used
Pallet gate actuator
The 300 mm stroke swings or lifts conveyor gates and pallet stops in warehouses, and the compact body fits behind guards where a full-length profile cylinder cannot.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X300-75 the Right Cylinder?
Note that the stop screw is a mechanical end stop for the extend stroke only; on air loss the piston still drifts, so it is not a mid-stroke lock or load-holding brake. If you need position feedback, specify the -S magnet variant and add CMSE or DMSE switches; this code ships without a magnet. Mount with FA flange or LB foot, and choose the B code instead if a male rod thread suits your tooling.
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 ACEJ80X300-75 FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push rises to 3518.6 N and pull to 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -75 code sets a 75 mm adjustment window: an external stop screw shortens the 300 mm extend stroke on site to any setting from 225 to 300 mm. It shortens the stroke only - it never extends it past 300 mm.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium barrel, S45C hard-chrome rod and fixed TPU bumpers at both ends. Switches need the optional -S magnet code: this model (without S) has no magnet, so no CMSE or DMSE switch will trigger. FA flange, LB foot, FTC brackets and I/Y rod knuckles mount directly on the ISO 21287 face.
