Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-75
The AirTAC Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-75 is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø32mm bore and 100mm 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 ACEJ32X100-75
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ32X100-75 pairs a 32 mm bore with a 100 mm stroke and a 75 mm trim window. At 0.5 MPa it pushes 402.1 N and pulls 345.6 N, and the external stop screw lets you shorten the extend stroke anywhere in the 25-100 mm range on site. The hard-anodized aluminium body with an S45C hard-chrome plated rod runs at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s.
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. As a rule of thumb, plan for roughly 240 N of usable work at 0.5 MPa, which lifts about 24 kg vertically - halve that for a 2:1 margin and match it against your real part weight. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the optional -S magnet enables CMSE / DMSE switches if you order it.

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 ACEJ32X100-75 Is Used
Weld fixture clamping
The 402.1 N push at 0.5 MPa holds sheet-metal panels in a weld jig, and the 75 mm window lets one cylinder serve several fixture variants from 25 to 100 mm.
Packaging line pushers
On a carton transfer line the 100 mm stroke indexes boxes between lanes at 30-500 mm/s, with the stop screw trimming the throw to match lane pitch.
Press-fit assist station
A small bearing press-fit cell uses the 563 N push at 0.7 MPa to seat bushings, with the short ISO 21287 body fitting inside the press frame.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-75 the Right Cylinder?
At 402.1 N push (0.5 MPa) this 32 mm bore suits clamping and positioning loads up to roughly 240 N of real work. Step down to the 25 mm bore (245.4 N push) for lighter fixtures, or up to the 40 mm bore (628.3 N push) when the load grows. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the piston still drifts, so add a separate holding valve for suspended loads. FA flange, LB foot and I/Y rod knuckles bolt to the ISO 21287 face; add the -S code if CMSE / DMSE sensing is needed later.
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 ACEJ32X100-75 FAQ
At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa push is 563 N and pull 483.8 N, with a theoretical maximum of 82 kgf at 1.0 MPa. It is double acting with an adjustable extend stroke (75 mm window, usable 25-100 mm), a 32 mm bore, 12 mm rod with female M8x1.25 thread, 1/8" PT ports, 0.15-1.0 MPa (22-145 psi) operating pressure, 1.5 MPa (215 psi) proof pressure, -20 to +70 C, and 30-500 mm/s speed.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA flange, LB foot and I/Y rod knuckles bolt straight to the standard face. Sensing is possible only if you order the optional -S magnet code, which then accepts CMSE / DMSE switches; this model without S has no magnet, so no switch can be mounted. A fixed TPU bumper at both ends absorbs end-of-stroke energy.
