About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X75-75
A double acting ISO 21287 compact cylinder, the ACEJ40X75-75 pairs a 40 mm bore with a 75 mm stroke that an external stop screw can trim anywhere in the 0-75 mm window. At 0.5 MPa it pushes 628.3 N and pulls 571.8 N, rising to 879.6 N at 0.7 MPa, with a theoretical ceiling of 128.1 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 would not fit.
Plan around roughly 377 N of real work at 0.5 MPa (about 60% of the push rating), which is close to 38 kg of horizontal load; halved again for a 2:1 margin, the rod lifts about 19 kg vertically. The hard-anodized aluminium body carries a hard-chrome S45C rod, fixed TPU bumpers decelerate both ends of travel, and the female M8x1.25 rod thread accepts standard knuckles. No magnet is fitted, so CMSE or DMSE switches need the optional -S code.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X75-75 Is Used
Jig clamping on CNC fixtures
The 0-75 mm adjustable window lets one cylinder serve several fixture heights, with 628.3 N push at 0.5 MPa holding workpieces firmly during machining.
Packaging line pusher gates
A 75 mm stroke diverts cartons between lanes at 30-500 mm/s, and the compact body fits the shallow frame depth of conveyor cross-members.
Press-fit of small bearings
About 377 N of usable force at 0.5 MPa seats bushings and bearings in housings, with the TPU bumper softening the end of each press cycle.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X75-75 the Right Cylinder?
For this 75 mm stroke class, a 32 mm bore gives 402.1 N push at 0.5 MPa while a 50 mm bore reaches 981.7 N; pick the 40 mm when your load sits between roughly 250 and 380 N of working force. The stop screw only shortens the extend stroke and is not a mid-stroke lock, so on air loss the piston still drifts. FA flange and LB foot mountings bolt to the ISO 21287 face, and the port is 1/8" PT. Order the -S variant 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 ACEJ40X75-75 FAQ
At 0.5 MPa it pushes 628.3 N and pulls 571.8 N; at 0.7 MPa push is 879.6 N and pull 800.5 N, with a theoretical maximum of 128.1 kgf at 1.0 MPa. The -75 code is a 75 mm adjustment window: an external stop screw shortens the 75 mm extend stroke on site anywhere in the 0-75 mm range. It cannot lengthen the stroke past 75 mm, and the stop is not a load-holding brake - on air loss the piston drifts.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, hard-chrome S45C rod, 1/8" PT ports and fixed TPU bumpers at both ends. FA flange and LB foot mountings plus I/Y rod knuckles bolt straight on. Position sensing requires the optional -S magnet code, which enables CMSE / DMSE switches; without -S no magnet is fitted.
