About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X250-50B
A double acting ISO 21287 compact cylinder, the ACEJ80X250-50B pairs an 80 mm bore with a 250 mm stroke that an external stop screw trims down to 200 mm on site, all inside a 50 mm adjustment window. 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. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses and gantries where a full-length body will not fit.
The hard-anodized aluminium body carries a hard-chromed S45C 20 mm rod with a male thread (B code), fixed TPU bumpers absorb end-of-stroke shock at both ends, and the 1/8" port suits bores 80 and up. Running spec: 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, air filtered to 40 um. No magnet is fitted; order the -S code if you later need CMSE / DMSE switch positions.

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 ACEJ80X250-50B Is Used
Pallet gate actuator
The 128 kg vertical-lift equivalent covers raising and lowering heavy gate arms on conveyor diverters, with the compact body fitting under low guard rails.
Machine slide feed
Feeds a 20 mm hard-chromed rod into a machining slide at 30-500 mm/s, with FA flange mounting keeping the short body rigid inside a tight fixture.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X250-50B the Right Cylinder?
If the machine must hold position against a falling load during a power loss, remember the stop screw is a mechanical end stop only and the rod will drift on air loss; add an external locking solution for that duty. FA flange or LB foot mountings bolt to the ISO 21287 face, and the male rod thread (B) takes standard rod accessories. The optional -S magnet enables CMSE / DMSE switches; this model ships without it.
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 ACEJ80X250-50B FAQ
The -50 code is a 50 mm adjustment window: an external stop screw shortens the 250 mm extend stroke to as little as 200 mm. It is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the rod still drifts if air is lost. Speed range is 30-500 mm/s and pressure is 0.15-1.0 MPa (22-145 psi).
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-chromed rod and fixed TPU bumpers at both ends. Sensors are not possible on this unit as ordered: the magnet is the optional -S code, so to run CMSE or DMSE switches you must order the -S variant. FA flange and LB foot mountings bolt straight to the standard face.
