About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-100
The ACEJ80X120-100 is a double acting AirTAC compact cylinder built to ISO 21287, with an adjustable extend stroke: an external stop screw trims the 120 mm stroke by up to 100 mm on site, giving a usable range of 20-120 mm. The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into heavy presses, clamping gantries and machine guards where a full-length body will not fit.
The hard-anodized aluminium body carries a S45C hard-chrome plated 20 mm rod, a fixed TPU bumper sits at both ends, and FA flange or LB foot mounts plus I/Y rod knuckles bolt straight to the ISO 21287 face. 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 ACEJ80X120-100 Is Used
Heavy clamping fixture on a CNC fixture
FA flange mounting on the ISO 21287 face secures workpieces of up to roughly 150 kg equivalent clamping demand, and the short body fits inside fixture plates too tight for a full-length profile cylinder.
Pallet gate and conveyor stopper actuation
LB foot mounting drives gates, lifters and stops on warehouse conveyor lines, where the 120 mm stroke trimmed down to 20 mm keeps the mechanism compact at the transfer point.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X120-100 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. If you need position sensing, order the -S variant, which carries the optional magnet for CMSE / DMSE switches; this model without the S code 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 ACEJ80X120-100 FAQ
The -100 code is a 100 mm adjustment window: an external stop screw shortens the 120 mm extend stroke by up to 100 mm, so the working range is 20-120 mm. It runs double acting on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, with a 1/8" PT port and an M12x1.75 female rod thread.
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 and a fixed TPU bumper at each end to absorb end-of-stroke energy. FA flange and LB foot mounts plus I/Y rod knuckles bolt straight to the standard face. Position sensing requires the optional -S magnet code - this model has no magnet fitted, so no CMSE or DMSE switch can be mounted unless the magnet is ordered.
