Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X40-40
The AirTAC Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X40-40 is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø32mm bore and 40mm stroke, 1/8" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X40-40
A double acting compact cylinder built to ISO 21287, the ACEJ32X40-40 pairs a 32 mm bore with a 40 mm stroke that an external stop screw trims anywhere from 0 to 40 mm on site. At 0.5 MPa it pushes 402.1 N and pulls 345.6 N, enough for clamping, ejecting and indexing in tight fixtures. The hard-anodized aluminium body with an S45C hard-chrome rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s.
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into guarded gantries and cramped jig plates. Plan on roughly 241 N of usable push at 0.5 MPa, which lifts about 12 kg vertically with a 2:1 margin. Fixed TPU bumpers absorb end-of-stroke shock at both ends, and the optional -S magnet enables CMSE / DMSE switches if position sensing is added later.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X40-40 Is Used
Fixture clamping on CNC machining centers
The 402.1 N push at 0.5 MPa clamps aluminum housings in a dedicated jig, and the stop screw lets the setter dial the clamp travel anywhere in the 0-40 mm window without changing cylinders.
Short-stroke part ejection from assembly stations
A 40 mm kick clears finished connectors off a pick nest in under a second at 500 mm/s, and the compact body fits where a full-length profile cylinder cannot.
Gate indexing on small packaging machines
The 345.6 N pull at 0.5 MPa retracts a sorting gate reliably, with the 1/8" port plumbed straight into the machine's valve manifold.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X40-40 the Right Cylinder?
At 402.1 N push (0.5 MPa) this 32 mm bore suits loads up to about 241 N in practice; step down to a 25 mm bore (245.4 N push) only if the pull force of 206.2 N is still enough, or up to a 40 mm bore (628.3 N push) for heavier clamps. The stop screw shortens the extend stroke only - it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA flange or LB foot mounts bolt to the ISO 21287 face, and the female M8x1.25 rod thread takes standard rod knuckles (I or Y). Order the -S code if CMSE / DMSE sensing is planned.
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 ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X40-40 FAQ
At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa push rises to 563 N and pull to 483.8 N. The theoretical maximum at 1.0 MPa is 82 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed is 30-500 mm/s. A practical working figure is about 241 N of push, roughly 12 kg of vertical lift with a 2:1 margin.
The -40 code is a 40 mm adjustment window: an external stop screw shortens the 40 mm extend stroke to any length down to 0, set with a wrench in minutes. Fixed TPU bumpers at both ends absorb end-of-stroke impact. The cylinder ships without a magnet; order the optional -S code to enable CMSE / DMSE switches. FA flange and LB foot mounts fit the standard ISO 21287 face.
