About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X160-20
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ80X160-20 pairs an 80 mm bore with a 160 mm stroke and a 20 mm trim window. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa, with a theoretical peak of 512.6 kgf at 1.0 MPa. A stop screw shortens the extend stroke on site by up to 20 mm, so the usable range is 140-160 mm; it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why this bore class fits deep clamping fixtures and guarded press stations where a full-length body cannot. The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod, a fixed TPU bumper sits at both ends, and the optional -S magnet enables CMSE / DMSE switches - this unit has no magnet fitted. Ports are 1/8" (PT), speed is 30-500 mm/s, and pressure runs 0.15-1.0 MPa (22-145 psi).

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 ACEJ80X160-20 Is Used
Injection-mould part ejection
The 140-160 mm adjustable extend range ejects deep-draw mouldings, and the compact body drops into press beds where an ISO 15552 profile cylinder is too long.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X160-20 the Right Cylinder?
If your fixture needs the stroke fixed at order time, the fixed-stroke ACE is the plainer choice; if the rod must not rotate, look at the TACE twin-guide. FA flange and LB foot mountings bolt to the ISO 21287 face, and the female M12x1.75 rod thread accepts standard rod knuckles. Note the stop screw only trims the extend stroke within the 20 mm window and never holds a load against air loss.
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 ACEJ80X160-20 FAQ
The -20 code is a 20 mm adjustment window: an external stop screw shortens the 160 mm extend stroke on site to any setting from 140 to 160 mm. It is a mechanical end stop only - on air loss the piston drifts, so do not rely on it to hold a load. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, 20 mm hard-chrome S45C rod and a fixed TPU bumper at each end. Position sensing requires the optional -S magnet code - this model has no magnet, so no CMSE or DMSE switch can be mounted unless you order the -S variant. Mounting options include FA flange and LB foot, and the female M12x1.75 rod thread takes standard knuckles.
