About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X150-40
The ACEJ32X150-40 is a double acting AirTAC compact cylinder built to ISO 21287, with a 32 mm bore and a 150 mm stroke that an external stop screw can trim by up to 40 mm on site, giving a usable extend range of 110-150 mm. At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa those rise to 563 N and 483.8 N, with a theoretical maximum of 82 kgf at 1.0 MPa. The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit.
Plan real work at roughly 241 N (about 0.6 of the push figure), which is around 24 kg of safe vertical push, or lift about 20 kg with a 2:1 margin. The hard-anodized aluminium body carries a hard-chrome plated S45C rod, fixed TPU bumpers absorb end-of-stroke energy at both ends, and the rod ends in a female M8x1.25 thread. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and this version has no magnet - order the optional -S code if you need CMSE / DMSE switch sensing.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X150-40 Is Used
Jig clamping on CNC fixtures
The 402.1 N push at 0.5 MPa clamps aluminium or steel workpieces in machining jigs, and the 110-150 mm adjustable range lets one cylinder serve fixtures of slightly different heights without re-plumbing.
Packaging line pushers
On a bottling or carton line, the 150 mm stroke diverts packs between lanes while the compact body fits under low guard rails, running at 30-500 mm/s to match line speed.
Small press and forming stations
With 563 N available at 0.7 MPa (82 kgf theoretical max), it handles light staking, embossing and snap-fit pressing on electronics assemblies where a full-length body would overhang the bench.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X150-40 the Right Cylinder?
At 32 mm bore this sits above the 25 mm size (245.4 N push at 0.5 MPa) and below the 40 mm size (628.3 N push at 0.5 MPa), so pick it when your load needs roughly 400 N of push at 0.5 MPa. The 150 mm stroke is within the 200 mm maximum standard stroke for this bore, so it ships as a standard build. Remember the -40 adjuster is a mechanical end stop for the extend stroke only: it sets where the rod stops, it does not lock or hold a load if air is lost. It bolts to FA flange or LB foot mounts and I/Y rod knuckles on the ISO 21287 face, and add the -S code if position sensing with CMSE / DMSE switches 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 ACEJ32X150-40 FAQ
Push is 402.1 N and pull 345.6 N at 0.5 MPa; at 0.7 MPa push is 563 N and pull 483.8 N, with a theoretical maximum of 82 kgf at 1.0 MPa. The -40 code is a 40 mm adjustment window: an external stop screw shortens the 150 mm extend stroke by up to 40 mm, so the usable range is 110-150 mm. It cannot lengthen the stroke beyond 150 mm, and it is an end stop, not a mid-stroke lock - the rod still drifts if air pressure is lost.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. Position sensing needs the optional -S magnet code - this model has no magnet fitted, so no CMSE / DMSE switch can be mounted unless you order -S. Mounting options include FA flange, LB foot, FTC brackets and I/Y rod knuckles; the rod thread is female M8x1.25 and the port is 1/8" PT.
