About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X75-30
The ACEJ32X75-30 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 75 mm stroke down by up to 30 mm, giving a usable range of 45-75 mm without changing hardware. At 0.5 MPa it delivers 402.1 N of push force, and 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.
In service terms, plan on roughly 240 N of real work at 0.5 MPa (about 60% of the rated push), which corresponds to lifting around 24 kg vertically, or about 12 kg with a 2:1 margin. The hard-anodized aluminium body carries a roller-burnished bore, the S45C rod is hard-chrome plated, and fixed TPU bumpers absorb end-of-stroke energy. Speed range is 30-500 mm/s and operating pressure is 0.15-1.0 MPa (22-145 psi).

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X75-30 Is Used
Fixture clamping with trimmed stroke
On a CNC machining fixture, the stop screw is set to 58 mm so the 402.1 N push seats the clamp shoe on the part without over-travel, and the 45-75 mm window lets the setter re-trim when a different workpiece is batched.
Packaging line pusher gate
A diverting gate on a bottling conveyor uses the 75 mm stroke at 30-500 mm/s to kick cartons off the lane, with the 345.6 N pull stroke retracting the gate clear of passing product.
Press-fit of small bushings
A bench-top arbor press for automotive bushings exploits the compact body inside a guarding frame, using the 563 N push at 0.7 MPa to seat parts while the TPU bumper quiets the return.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X75-30 the Right Cylinder?
Bore 32 sits in the mid force band: step down to bore 25 (245.4 N push at 0.5 MPa) for lighter clamping, or up to bore 40 (628.3 N) when the load grows. The 75 mm stroke is well inside the 200 mm maximum standard stroke for this bore. Remember the stop screw only shortens the extend stroke within the 30 mm window and is not a mid-stroke lock: on air loss the piston still drifts, so add a separate holding valve if the load must stay put. FA flange or LB foot mounts bolt to the ISO 21287 face, and if you need position feedback, order the -S variant so CMSE / DMSE switches can be used; this unit has no magnet fitted.
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 ACEJ32X75-30 FAQ
At 0.5 MPa the 32 mm bore gives 402.1 N push and 345.6 N pull; at 0.7 MPa it reaches 563 N push and 483.8 N pull, with a theoretical maximum of 82 kgf at 1.0 MPa. For sizing, treat about 240 N (60% of the push rating) as usable work, which lifts roughly 24 kg vertically, or about 12 kg with a 2:1 safety margin. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
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, 1/8" PT ports and fixed TPU bumpers at both ends. FA flange or LB foot mounts bolt straight to the ISO 21287 face, and the female M8x1.25 rod thread accepts standard knuckles. Position sensing requires the optional -S magnet with CMSE / DMSE switches; this model, ordered without S, has no magnet fitted.
