About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-20
The ACEJ32X100-20 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. A stop screw on the 32 mm bore body trims the 100 mm stroke by up to 20 mm on site, giving a usable range of 80-100 mm without swapping the cylinder. At 0.5 MPa it pushes 402.1 N and pulls 345.6 N, and the short 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 cannot.
Plan on roughly 240 N of real work at 0.5 MPa (about 0.6 of the push rating), which corresponds to lifting about 24 kg vertically, or about 12 kg with a 2:1 margin. The hard-anodized aluminium body carries a 12 mm S45C hard-chrome rod with a female M8x1.25 thread, and a fixed TPU bumper at each end absorbs end-of-stroke impact. Air supply is filtered to 40 um at 0.15-1.0 MPa (22-145 psi), speed runs 30-500 mm/s, and the optional -S magnet enables CMSE / DMSE switches; this model has no magnet fitted.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
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 ACEJ32X100-20 Is Used
Fixture clamping on CNC pallets
The 402.1 N push at 0.5 MPa clamps aluminium or small steel workpieces, and the 80-100 mm adjustable range lets one cylinder serve several pallet heights.
Packaging line push-off stations
With about 24 kg of vertical-lift equivalent, the 32 mm bore nudges cartons or trays off a conveyor at 30-500 mm/s inside tight guarding thanks to the short body.
Small press and forming stations
563 N at 0.7 MPa suits light staking or marking of brackets, with the stop screw dialing the exact extend position per product changeover.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-20 the Right Cylinder?
Size up or down by force: the 25 mm bore delivers 245.4 N push at 0.5 MPa, while the 40 mm bore reaches 628.3 N, so the 32 mm bore at 402.1 N sits in the middle for clamping and pressing fixtures in the 20-60 kg load class. The stop screw only shortens the extend stroke and is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. Mount with FA flange or LB foot on the ISO 21287 face, add I or Y rod knuckles as needed, and order the -S code if you want position sensing with 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 ACEJ32X100-20 FAQ
At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa it pushes 563 N and pulls 483.8 N. The theoretical maximum is 82 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and the extend stroke is trimmable from 100 mm down to 80 mm via the stop screw.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends and FA flange or LB foot mounting on the standard face. Position sensing requires the optional -S magnet ordered with the cylinder; without it no CMSE or DMSE switch can be mounted.
