About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X75-40B
The ACEJ80X75-40B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 75 mm stroke by up to 40 mm on site, giving a usable range of 35-75 mm. At 0.5 MPa the 80 mm bore pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N on the extend stroke at 0.7 MPa. As a rule of thumb, plan on roughly 1500 N of real work at 0.5 MPa rather than the full rating.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this heavy-thrust cylinder still fits tight press fixtures and guarded cells. The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod, a fixed TPU bumper sits at each end, and the male rod thread (B code) bolts straight to standard tooling. Note: no magnet is fitted on this model, so CMSE / DMSE switches need the optional -S code.

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 ACEJ80X75-40B Is Used
Pneumatic press fixture
The 2513.3 N extend force at 0.5 MPa stakes, swages or clinches aluminium brackets, and the 40 mm window lets you dial the 75 mm stroke down to 35 mm for shallow forming dies.
Clamping gantry in a guarded cell
The compact body, roughly half the mounting length of an ISO 15552 profile cylinder, slots under low machine guards to clamp steel castings before a drilling cycle.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X75-40B the Right Cylinder?
If your job needs a mid-stroke hold against air loss, remember the stop screw is a mechanical end stop only - the piston still drifts when pressure drops, so add a separate locking solution. FA flange or LB foot mounting plus I/Y rod knuckles suit jig work; order the -S variant if position sensing via CMSE / DMSE switches matters.
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 ACEJ80X75-40B 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; theoretical maximum is 512.6 kgf at 1.0 MPa. The -40 code sets a 40 mm adjustment window: a stop screw on the front cover shortens the 75 mm extend stroke by up to 40 mm, so the working range is 35-75 mm. It shortens the stroke only - it never extends past 75 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and a fixed TPU bumper sits at each end.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body and 20 mm hard-chrome S45C rod, about 50% shorter in mounting length than an ISO 15552 profile cylinder. The 1/8" port depends on the 80 mm bore. FA flange and LB foot mounts bolt to the standard face. Switches are not possible on this unit as ordered: the magnet is the optional -S code, so order ACEJ80X75-40SB if you need CMSE / DMSE reed or solid-state switches.
