Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X250-75S
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X250-75S is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 250mm stroke, 1/8" air ports and a hard-anodized aluminium body.

About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X250-75S
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ80X250-75S pairs an 80 mm bore with a 250 mm stroke and a 75 mm adjustment 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 maximum of 512.6 kgf at 1.0 MPa. The external stop screw trims the extend stroke anywhere in the 175-250 mm range, so one cylinder covers several fixture positions without swapping hardware.
The hard-anodized aluminium body with an S45C hard-chrome plated 20 mm rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters on long-stroke gantries where every millimetre of envelope counts. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the fitted -S magnet lets CMSE or DMSE switches report end positions.

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 ACEJ80X250-75S Is Used
Gate actuator on bottling line guards
The short ISO 21287 body fits behind machine guards where an ISO 15552 profile cylinder would overhang, and the stop screw dials the gate opening to match each bottle format.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X250-75S the Right Cylinder?
Remember the stop screw is a mechanical end stop, not a mid-stroke lock - on air loss the piston still drifts, so add a separate clamp if you must hold position.
Mounting drops straight onto the ISO 21287 face: FA flange or LB foot brackets plus I and Y rod knuckles bolt on without adaptation. This model carries the -S magnet, so CMSE / DMSE switches can be added for end-of-stroke sensing. Ports are 1/8" on both ends, and speed runs 30-500 mm/s across 0.15-1.0 MPa (22-145 psi) supply.
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 ACEJ80X250-75S 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 -75 code sets a 75 mm adjustment window: an external stop screw shortens the 250 mm extend stroke on site, giving a usable range of 175-250 mm. The stop is a mechanical end stop only - it does not lock or hold a load if air is lost.
It is an ISO 21287 compact cylinder whose hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends to absorb end-of-stroke shock. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted in the body slots. FA flange, LB foot and FTC brackets plus I and Y rod knuckles bolt straight to the ISO 21287 face; the rod end is female M12x1.75 and ports are 1/8" PT.
