About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X250-30S
The ACEJ80X250-30S 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 30 mm, giving a usable range of 220-250 mm without swapping the cylinder. At 0.5 MPa the 80 mm bore pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa. Air to both ports, a fixed TPU bumper at each end, speed 30-500 mm/s and a 0.15-1.0 MPa (22-145 psi) operating band cover most heavy clamp-and-press work.
The hard-anodized aluminium body with an S45C hard-chrome plated 20 mm rod 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 reach. Because the -S magnet is fitted, CMSE or DMSE reed and solid-state switches can be clipped anywhere along the body slots for end-of-stroke signals.

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 ACEJ80X250-30S Is Used
Lifting fixture clamps on a weld cell
The theoretical 512.6 kgf class at 1.0 MPa gives about 153 kg of practical vertical lift at 0.5 MPa, enough to raise and clamp weld fixtures; the short ISO 21287 body fits under low gantry rails.
Gate and chute diverters in bottling lines
Double acting air drives heavy diverter gates both ways at 30-500 mm/s, while the fitted -S magnet with CMSE / DMSE switches confirms gate position to the PLC at each end of the trimmed 250 mm stroke.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X250-30S the Right Cylinder?
Remember the stop screw only shortens the extend stroke and is not a mid-stroke lock - on air loss the piston still drifts, so support the load separately. FA flange or LB foot mountings bolt to the ISO 21287 face, and the fitted -S magnet pairs with CMSE / DMSE switches for position feedback.
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 ACEJ80X250-30S FAQ
The ordered stroke is 250 mm and the -30 stop screw trims the extend stroke by up to 30 mm, so the usable range is 220-250 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the port is 1/8" PT with an M12x1.75 female rod thread.
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-chrome rod and fixed TPU bumpers at both ends that soften the stroke ends without ever holding a load. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches mount in the body slots for end-of-stroke detection; FA flange and LB foot brackets bolt straight to the standard face.
