About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-20B
The ACEJ32X100-20B is a double acting AirTAC compact cylinder built to ISO 21287, with a 32 mm bore and a 100 mm stroke that an external stop screw trims by up to 20 mm on site, giving a usable extend range of 80-100 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 peak of 82 kgf at 1.0 MPa. The B code gives a male rod thread on the 12 mm S45C hard-chrome rod, and the 1/8" port is fixed by the bore.
The hard-anodized aluminium 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 on roughly 240 N (about 24 kgf) of real work at 0.5 MPa, which is a sensible margin under the 402.1 N rating - enough to lift about 12 kg vertically with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke energy, 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 ACEJ32X100-20B Is Used
Jig clamping on CNC fixtures
The 80-100 mm adjustable extend range lets a machinist dial in clamp travel per fixture, with 402.1 N push at 0.5 MPa holding aluminum housings against locators.
Carton pusher on packaging lines
A short ISO 21287 body fits under low guarding, and the male rod thread (B code) bolts straight to a pusher plate for 100 mm box divert strokes.
Small-part press-fit station
About 240 N of usable force at 0.5 MPa seats bushings and dowels into plastic housings, with the TPU bumper softening every cycle at 30-500 mm/s.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-20B the Right Cylinder?
Size check: a 25 mm bore gives 245.4 N push at 0.5 MPa, so if your load sits near 150 N the ACEJ25X100-20 is cheaper; step up to the 40 mm bore (628.3 N push) when loads approach 350 N or you need more rod stiffness over the 100 mm stroke. Remember the stop screw only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the rod can drift if air is lost. Mount with FA flange or LB foot on the ISO 21287 face, add I or Y rod knuckles for side misalignment, and order the -S code if you want the magnet for CMSE / DMSE switches.
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 ACEJ32X100-20B 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; theoretical maximum is 82 kgf at 1.0 MPa. It is double acting with a 32 mm bore, 100 mm stroke adjustable down to 80 mm via the stop screw, 12 mm male-thread rod, 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 hard-anodized aluminium ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder. Mounting options include FA flange, LB foot and FTC brackets plus I/Y rod knuckles. Position sensing requires the optional -S magnet code - this model has no magnet, so CMSE or DMSE switches only work if you order the -S version.
