Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-50B
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-50B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 80mm stroke, 1/8" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-50B
The ACEJ80X80-50B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. The -50 code means an external stop screw trims the extend stroke anywhere from 30 to 80 mm on site, so one cylinder serves several jig positions. The male rod thread (B code) bolts straight to tooling plates.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in guarded presses and gantry clamps where every millimetre of envelope counts. A fixed TPU bumper at each end absorbs end-of-stroke impact, and the hard-anodized aluminium body with an S45C hard-chrome plated 20 mm rod resists wear in continuous production duty.

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 ACEJ80X80-50B Is Used
Gantry hold-down clamp
Mounted under a machining-centre gantry, the short body fits where an ISO 15552 profile cylinder would not, clamping aluminium extrusions with about 150 kgf of usable force.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-50B 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 it is not a load-holding lock. Mount with FA flange or LB foot brackets, and if you need position sensing, order the -S variant to enable CMSE / DMSE switches; this model has no magnet fitted. Speed range is 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).
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 ACEJ80X80-50B FAQ
Push is 2513.3 N and pull 2356.2 N at 0.5 MPa; at 0.7 MPa push reaches 3518.6 N, and the theoretical maximum is 512.6 kgf at 1.0 MPa. It is double acting with an 80 mm stroke adjustable down to 30 mm via the -50 stop screw, runs at 30-500 mm/s on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, with a 1.5 MPa (215 psi) proof pressure and a 1/8" PT port.
It is an ISO 21287 compact cylinder: hard-anodized aluminium body, S45C hard-chrome plated 20 mm rod, threaded aluminium covers 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 to the standard face. This version has no magnet; order the -S code to enable CMSE or DMSE switches.
