About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X300-20
A heavy-duty double acting ISO 21287 compact cylinder, the ACEJ80X300-20 pairs an 80 mm bore with a 300 mm stroke and a 20 mm adjustable window: an external stop screw trims the extend stroke anywhere in the 280-300 mm range without touching the machine.
The hard-anodized aluminium body with an S45C hard-chrome plated 20 mm rod runs at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s, with a fixed TPU bumper at each end. Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into presses, gantries and clamping fixtures where a full-length body will not fit. FA flange and LB foot mounts plus I/Y rod knuckles bolt to the standard ISO 21287 face.

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 ACEJ80X300-20 Is Used
Clamp fixtures on machining lines
FA flange mounting and the female M12x1.75 rod thread drop straight into CNC fixture plates for clamping cast housings, with LB foot mounts available for horizontal slide actuation.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X300-20 the Right Cylinder?
Remember the stop screw is a mechanical end stop only - on air loss the piston drifts, so add a separate valve or lock for load holding. Ports are 1/8" on this bore; the rod end is female M12x1.75. Order the -S code if you later need CMSE / DMSE switch positions - this version ships without a magnet.
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 ACEJ80X300-20 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 pull to 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -20 code gives a 20 mm adjustment window: an external stop screw shortens the 300 mm extend stroke to any setting between 280 and 300 mm. It is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost.
It is an ISO 21287 compact cylinder - about 50% shorter in mounting length than an ISO 15552 profile cylinder - with a hard-anodized aluminium body, S45C hard-chrome 20 mm rod, threaded covers and fixed TPU bumpers at both ends. It runs on 40 um filtered air at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, -20 to +70 C. This version has no magnet; order the optional -S code to enable CMSE / DMSE switches. Mounting: FA flange, LB foot, plus I/Y rod knuckles.
