About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X45-30SB
The ACEJ80X45-30SB is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. The -30 code gives a 30 mm adjustment window: an external stop screw trims the 45 mm extend stroke down to 15 mm on site, so one cylinder covers a 15-45 mm range without re-plumbing. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight press fixtures and guarded gantries a full-length body cannot reach.
Build quality matches the force class: a roller-burnished, hard-anodized aluminium body, an S45C hard-chrome plated 20 mm rod, and a fixed TPU bumper at each end to absorb end-of-stroke shock. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clamped into the body slots for end-position sensing. Speed range is 30-500 mm/s across 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 ACEJ80X45-30SB Is Used
Short-stroke press station
With 3518.6 N available at 0.7 MPa, this bore suits light staking and marking heads where the compact body must fit inside a guarded press frame - about 50% shorter than an ISO 15552 profile cylinder.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X45-30SB the Right Cylinder?
If your jig needs under 1500 N of working force, the 63 mm saves space and air; if you are near the limit at 0.5 MPa, go 100 mm rather than raising pressure. Remember the stop screw only shortens the extend stroke and is not a mid-stroke lock - on air loss the piston drifts, so add a separate holding valve for suspended loads. Mounting: FA flange or LB foot brackets bolt to the ISO 21287 face, with I and Y rod knuckles on the male-threaded rod end. Ports are 1/8" on this bore, and the fitted -S magnet accepts CMSE / DMSE switches.
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 ACEJ80X45-30SB FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push is 3518.6 N and pull 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -30 code is a 30 mm adjustment window: an external stop screw shortens the 45 mm extend stroke to any setting from 15 to 45 mm. It is a mechanical end stop only - it never holds a load mid-stroke, and the piston drifts if air is lost. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, air filtered to 40 um.
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 hard-anodized aluminium body, S45C hard-chrome 20 mm rod and fixed TPU bumpers at both ends. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be slid into the body slots for position feedback. FA flange and LB foot brackets mount on the standard ISO 21287 face, and the male rod thread (B code) takes I or Y knuckles; the port thread is PT with a 1/8" connection.
