About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X250-50
A double acting ISO 21287 compact cylinder, the ACEJ80X250-50 pairs an 80 mm bore with a 250 mm stroke that an external stop screw trims by up to 50 mm on site, giving a usable extend range of 200-250 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 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 simply will not fit.
The hard-anodized aluminium body carries a hard-chromed S45C 20 mm rod, fixed TPU bumpers absorb end-of-stroke shock at both ends, and the rod end is female M12x1.75 with a 1/8" PT port. FA flange and LB foot mounts bolt to the standard ISO 21287 face. Note that the stop screw sets the end of stroke only - it is not a mid-stroke lock, so the piston still drifts if air is lost.

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 ACEJ80X250-50 Is Used
Bench-top crimping press
With about 1508 N of dependable force at 0.5 MPa, the 80 mm bore handles light crimping and staking of terminals, while the 200-250 mm adjustable range lets one cylinder serve several die heights.
Pallet-stacker pusher arm
The 250 mm stroke pushes cartons or pallets sideways on transfer cars, and the compact body saves roughly half the mounting length of an ISO 15552 profile cylinder in tight chassis frames.
Vertical lift-and-lower gantry
Halving the 256 kg vertical-lift equivalent gives a safe margin of about 128 kg per cylinder, ideal for raising fixture plates or lids on automated assembly lines.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X250-50 the Right Cylinder?
If 2513.3 N at 0.5 MPa is more than your jig needs, the 63 mm bore delivers 1558.6 N in the same compact envelope; if you need more, the 100 mm bore reaches 3927.0 N. Both neighbours share the 1/8" port class upward and keep the ISO 21287 mounting face. Order the -S code if you want the optional magnet for CMSE / DMSE switches - without it no position sensing is possible. Choose FA flange or LB foot to match your fixture, and remember the adjuster trims the extend stroke down within the 50 mm window; it never extends travel past 250 mm.
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 ACEJ80X250-50 FAQ
Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and rod speed 30-500 mm/s on filtered air. The extend stroke is adjustable from 200-250 mm via the stop screw within the -50 window.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, threaded aluminium covers, a hard-chromed S45C 20 mm rod and fixed TPU bumpers at both ends - about 50% shorter in mounting length than an ISO 15552 profile cylinder. FA flange and LB foot mounts bolt straight to the standard face. Position sensing requires the optional -S magnet code; with it, CMSE / DMSE switches mount in the body slots, but without -S no magnet is fitted.
