About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X90-30
The ACEJ32X90-30 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. A stop screw on the external adjuster trims the 90 mm stroke by up to 30 mm on site, giving a usable range of 60-90 mm without changing the cylinder. At 0.5 MPa the 32 mm bore delivers 402.1 N push and 345.6 N pull, rising to 563 N push at 0.7 MPa, which suits clamping and positioning in tight machine frames. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits where a full-length cylinder will not.
For sizing, treat roughly 0.6 of the push force as usable work at 0.5 MPa, about 240 N, which is roughly 24 kg of vertical lift with a 2:1 margin. The hard-anodized aluminium body carries a S45C hard-chrome plated 12 mm rod, a fixed TPU bumper at each end absorbs end-of-stroke energy, and speeds run 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). This unit has no magnet fitted; order the optional -S code if you later need CMSE / DMSE switch sensing.

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 ACEJ32X90-30 Is Used
Fixture clamping on CNC jigs
The 402.1 N push at 0.5 MPa clamps aluminium housings on machining fixtures, and the 60-90 mm adjustable range lets one cylinder serve several jig depths.
Packaging line push-off
A 240 N usable force slides cartons off a conveyor at up to 500 mm/s, while the compact body fits under low guarding where an ISO 15552 profile cylinder is too long.
Small part press-fit station
About 24 kg of vertical lift with a 2:1 margin presses bearings into small housings; the stop screw sets the exact bottom position per part.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X90-30 the Right Cylinder?
Compare before you commit: the 25 mm bore pushes 245.4 N at 0.5 MPa, while the 40 mm bore reaches 628.3 N, so pick the 32 mm when your load sits between those bands. Remember the adjuster is a mechanical end stop only - it shortens the extend stroke within the 30 mm window and does not hold a load if air is lost. FA flange or LB foot mounts bolt to the ISO 21287 face, and the female M8x1.25 rod thread accepts standard rod knuckles (I or Y). If position feedback matters, specify the -S variant so CMSE / DMSE switches can ride the body slots.
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 ACEJ32X90-30 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. The -30 code sets a 30 mm adjustment window: an external stop screw shortens the 90 mm extend stroke anywhere down to 60 mm. It is an end stop, not a load lock - on air loss the piston still drifts. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends. This version has no magnet, so no sensor can be mounted; the optional -S code adds the magnet for CMSE / DMSE switches. FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to the ISO 21287 face, and the rod end is female M8x1.25 with a 1/8" port.
