About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X300-20B
The ACEJ80X300-20B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 300 mm stroke down by up to 20 mm on site, giving a usable range of 280-300 mm without changing the cylinder. At the 80 mm bore it pushes 2513.3 N and pulls 2356.2 N at 0.5 MPa, rising to 3518.6 N at 0.7 MPa, with a theoretical peak 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 300 mm stroke fits deep slides and long-reach gantries that a full-length profile cylinder cannot. A hard-anodized aluminium body carries an S45C hard-chrome plated 20 mm rod, fixed TPU bumpers absorb end-of-stroke energy at both ends, and the male rod thread (B code) bolts directly to standard tooling. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.

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 ACEJ80X300-20B Is Used
Press-feed ejector in stamping shops
With about 1508 N of practical working force at 0.5 MPa, the 80 mm bore ejects stamped brackets from a die, while the male rod thread picks up a knuckle for off-center parts.
Bottle-lane diverter on filling lines
A 300 mm stroke sweeps a full conveyor lane of bottles in one move, and the compact body halves the mounting length compared with an ISO 15552 profile cylinder under low guards.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X300-20B the Right Cylinder?
Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the rod can still drift if air is lost. Mount with FA flange or LB foot on the ISO 21287 face, add I or Y rod knuckles for side misalignment, and order the -S code if you later need CMSE / DMSE switches - this model has no magnet fitted.
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 ACEJ80X300-20B FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push rises to 3518.6 N, and the theoretical maximum is 512.6 kgf at 1.0 MPa. The -20 code is a 20 mm adjustment window: turn the external stop screw to shorten the 300 mm extend stroke anywhere in a 280-300 mm range. It is a mechanical end stop only - it never locks or holds a load if air pressure drops.
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, 1/8" ports and fixed TPU bumpers at both ends. Sensors are possible only with the optional -S magnet code, which enables CMSE / DMSE switches; this model (no S code) has no magnet, so no switch can be mounted.
