About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X55-20SB
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ80X55-20SB pairs an 80 mm bore with a 55 mm stroke and a 20 mm adjustment window. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa those figures rise to 3518.6 N and 3298.7 N, with a theoretical 512.6 kgf at 1.0 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses and fixtures where a full-length profile cylinder will not fit.
The hard-anodized aluminium body carries a hard-chrome plated S45C rod with a male thread (the B code), and a fixed TPU bumper sits at both ends. An external stop screw trims the extend stroke anywhere in the 35-55 mm range, so one cylinder serves several die heights. The fitted -S magnet accepts CMSE / DMSE switches for end-of-stroke signalling.

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 ACEJ80X55-20SB Is Used
Short-stamp marking press
A compact body that is about 50% shorter than an ISO 15552 profile cylinder fits inside a guarded stamping head, delivering 3518.6 N at 0.7 MPa for date-code marks.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X55-20SB the Right Cylinder?
The stop screw is a mechanical end stop only - on air loss the piston drifts, so add a separate valve or lock if the load must be held. FA flange or LB foot mountings bolt to the ISO 21287 face, and the male rod thread suits rod knuckles. Stroke is trimmable within the ordered 20 mm window; it cannot extend past 55 mm.
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 ACEJ80X55-20SB 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, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -20 code is a 20 mm adjustment window: an external stop screw shortens the 55 mm extend stroke, giving a usable range of 35-55 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the port is 1/8" PT with a male rod thread.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted in the body slots for position feedback. FA flange and LB foot mountings plus I and Y rod knuckles bolt straight to the standard ISO 21287 face.
