About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X250-10
The ACEJ80X250-10 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 250 mm stroke by up to 10 mm on site, giving a usable range of 240-250 mm without changing the cylinder. At 0.5 MPa the 80 mm bore delivers 2513.3 N on the extend stroke and 2356.2 N on retract, rising to 3518.6 N / 3298.7 N at 0.7 MPa. As a rule of thumb, plan on roughly 1500 N of real work at 0.5 MPa, which is about 153 kg of vertical lifting capacity with a sensible margin.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this 250 mm stroke unit fits deep into presses, gantries and guarding where a full-length body would not reach. The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod, a fixed TPU bumper decelerates the piston at each end, and the 1/8" ports take air at 0.15-1.0 MPa (22-145 psi) with speeds of 30-500 mm/s. This version has no magnet; 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 ACEJ80X250-10 Is Used
Vertical lift in a packaging gantry
With about 153 kg of practical vertical lifting capacity at 0.5 MPa, the 80 mm bore raises trays or chutes on a packaging line, while the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder inside the gantry frame.
Clamping fixture on a machining centre
LB foot mounting and the female M12x1.75 rod thread drop straight into a standard fixture, holding machined housings against a jig with the extend stroke trimmed precisely via the stop screw.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X250-10 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 add a separate valve or lock if the load must be held. FA flange and LB foot mountings bolt to the ISO 21287 face, and the female M12x1.75 rod thread accepts standard rod knuckles such as the I or Y types.
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 ACEJ80X250-10 FAQ
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 maximum of 512.6 kgf at 1.0 MPa. The -10 code is a 10 mm adjustment window: an external stop screw shortens the 250 mm extend stroke by up to 10 mm, so the working range is 240-250 mm. It cannot lengthen the stroke past 250 mm, and it is an end stop only, not a mid-stroke lock. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, an S45C hard-chrome plated 20 mm rod and 1/8" ports, and its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder. A fixed TPU bumper at each end absorbs end-of-stroke energy. This model has no magnet, so no switch can be mounted; order the -S version to enable CMSE / DMSE reed or solid-state switches. FA flange and LB foot mountings are available, and the rod end is female M12x1.75.
