Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X45-20
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X45-20 is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 45mm 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 ACEJ80X45-20
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ80X45-20 pairs an 80 mm bore with a 45 mm stroke and a 20 mm on-site 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 ceiling of 512.6 kgf at 1.0 MPa. Air is the only fluid, filtered to 40 um, across 0.15-1.0 MPa (22-145 psi).
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses and gantries where a full-length body will not fit. FA flange and LB foot brackets bolt straight to the ISO 21287 face, and the fixed TPU bumper at each end absorbs end-of-stroke energy.

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 ACEJ80X45-20 Is Used
Short-stroke press station
A compact 80 mm bore delivering 2513.3 N at 0.5 MPa suits a bench-top crimping or staking fixture where the 25-45 mm adjustable window lets you set the ram travel per part.
Clamping on a machining line
With 2356.2 N of pull at 0.5 MPa, this cylinder retracts a swing clamp or fixture riser on a CNC pallet changer, and the short body fits inside the guard.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X45-20 the Right Cylinder?
Remember the stop screw only trims the extend stroke within the ordered 20 mm window (usable range 25-45 mm); it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts on air loss. If you need position sensing, order the -S variant so CMSE / DMSE switches can be used; this non-S model carries no 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 ACEJ80X45-20 FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa it pushes 3518.6 N and pulls 3298.7 N; theoretical maximum is 512.6 kgf at 1.0 MPa. The -20 code gives a 20 mm adjustment window: an external stop screw shortens the 45 mm extend stroke on site, so the usable range is 25-45 mm. It cannot lengthen the stroke past 45 mm, and the stop is not a load-holding brake.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, S45C hard-chrome plated 20 mm rod, M12x1.75 female rod thread and 1/8" PT ports, running 30-500 mm/s between -20 and +70 C with a fixed TPU bumper at both ends. The body saves about 50% of the mounting length of an ISO 15552 profile cylinder. FA flange and LB foot brackets bolt to the ISO 21287 face. This version has no magnet; order the optional -S code to enable CMSE / DMSE switches.
