About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X90-75B
The ACEJ80X90-75B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 90 mm stroke anywhere inside the ordered 75 mm window, giving a usable range of 15-90 mm without changing the cylinder. At 0.5 MPa the 80 mm bore pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push rises to 3518.6 N, with a theoretical ceiling of 512.6 kgf at 1.0 MPa.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this 80 mm bore fits clamping fixtures and gantries where a full-length body will not. A hard-anodized aluminium body carries an S45C hard-chrome plated 20 mm rod, fixed TPU bumpers decelerate both ends, and the male rod thread (B code) bolts directly to standard tooling. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the 1/8" port is determined by the bore. Note that the stop screw is a mechanical end stop only: on air loss the piston still drifts, so it is not a mid-stroke lock. If position feedback is needed later, order the -S variant with the optional magnet for CMSE / DMSE switches.

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 ACEJ80X90-75B Is Used
Multi-width pallet clamping
A stop screw trims the extend stroke anywhere from 15 to 90 mm, so one cylinder clamps pallets of different heights on a packaging line by turning the adjuster instead of swapping cylinders.
Press-fit stations on tight frames
The body is about 50% shorter than an ISO 15552 profile cylinder, letting an 80 mm bore deliver 3518.6 N at 0.7 MPa inside compact CNC tending and assembly gantries.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X90-75B the Right Cylinder?
If your clamping or pressing load sits near 1500 N of working force, the 80 mm bore gives comfortable headroom at 0.5 MPa. Choose the -75 window when one cylinder must serve several product widths on the same fixture, and remember the trim only shortens the extend stroke, it never lengthens it past 90 mm. Mount via FA flange or LB foot on the ISO 21287 face, add I or Y rod knuckles where side alignment matters, and specify the -S magnet code at order time if CMSE / DMSE sensing will be required.
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 ACEJ80X90-75B FAQ
Push is 2513.3 N and pull is 2356.2 N at 0.5 MPa; at 0.7 MPa push reaches 3518.6 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -75 code is a 75 mm adjustment window: an external stop screw shortens the 90 mm extend stroke down to 15 mm on site. It is a mechanical end stop, not a load lock, so the rod still drifts if air is lost. Operating range is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
It is an ISO 21287 compact cylinder, roughly 50% shorter in mounting length than an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome plated 20 mm rod, and fixed TPU bumpers at both ends. The rod end is male thread (B code) and the port is 1/8". Switches are not available on this unit as ordered: this model has no magnet. The optional -S magnet code enables CMSE / DMSE reed or solid-state switches, so specify it when ordering if position feedback is planned. FA flange and LB foot mountings bolt to the standard ISO 21287 face.
