About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-75SB
The ACEJ80X80-75SB is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 80 mm stroke by up to 75 mm, giving a usable range of 5-80 mm without changing the cylinder. At 0.5 MPa the 80 mm bore delivers 2513.3 N on extend and 2356.2 N on retract, rising to 3518.6 N at 0.7 MPa. The male rod thread (B code) bolts straight into clevis-style tooling, and the fitted -S magnet lets CMSE / DMSE switches report end positions from day one.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into press fixtures and gantries where a full-length body will not reach. A fixed TPU bumper at each end absorbs end-of-stroke shock, the hard-anodized aluminium body resists wear, and the S45C hard-chrome rod stands up to side loading in daily production.

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 ACEJ80X80-75SB Is Used
Short-stroke press fixture
Trim the stroke down to 5 mm for a stamping or marking head on an aluminium extrusion line, where 2513.3 N at 0.5 MPa is enough for light forming work.
Pallet gate actuator
Swing or lift a gate arm on a warehouse conveyor with the full 80 mm stroke, using the male rod thread to pick up an existing clevis pin.
Machine guard interlock clamp
Clamp a CNC machine guard closed with about 153 kg of usable force, and let the fitted magnet drive a CMSE switch to prove the guard is locked.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X80-75SB the Right Cylinder?
Size the load first: at 0.5 MPa this bore pushes 2513.3 N, so keep continuous working loads near 1508 N or less. If your job needs under 1374 N, the 50 mm bore is lighter and cheaper; if you need beyond 3518 N, step up to the 100 mm bore at 3927 N. Remember the stop screw is a mechanical end stop only - on air loss the rod still drifts, so add a separate holding valve where a load must stay put. Match FA flange or LB foot brackets to the ISO 21287 face, and order CMSE or DMSE switches to pair with the fitted -S 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 ACEJ80X80-75SB FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa those rise to 3518.6 N and 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -75 code sets a 75 mm adjustment window: an external stop screw shortens the 80 mm extend stroke anywhere down to 5 mm. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), from -20 to +70 C at 30-500 mm/s. The stop is an end stop, not a mid-stroke lock.
This 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 both ends to soften end-of-stroke impact. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clamped onto the body for end-position sensing. FA flange, LB foot and FTC brackets plus I and Y rod knuckles bolt to the standard ISO 21287 mounting face, and the male rod thread (B code) suits existing clevis tooling. Port is 1/8" PT.
