About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X90-10
The ACEJ40X90-10 is a double acting AirTAC compact cylinder built to ISO 21287, with a 40 mm bore and a 90 mm stroke that an external stop screw trims by up to 10 mm on site, giving a usable extend range of 80-90 mm. At 0.5 MPa it pushes 628.3 N and pulls 571.8 N, rising to 879.6 N at 0.7 MPa. The hard-anodized aluminium body and hard-chrome S45C rod suit high-cycle jig work, and the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder.
For sizing the load, plan on roughly 377 N (about 38 kg) of real work at 0.5 MPa instead of the full 628.3 N rating; halved again for a 2:1 margin, the rod lifts about 32 kg vertically. The fixed TPU bumper at each end absorbs end-of-stroke shock, speed runs 30-500 mm/s, and the optional -S magnet enables CMSE / DMSE switches - this unit 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 572 N |
| 0.7 MPa | 880 N | 800 N |
| Max (@1.0 MPa) | 128 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 ACEJ40X90-10 Is Used
Clamp fixture on a CNC machining cell
The 628.3 N push at 0.5 MPa holds steel parts in a milling fixture, and the 10 mm window lets the setter dial the clamp travel between 80 and 90 mm without changing the cylinder.
Small press-fit station for bearings
With 879.6 N available at 0.7 MPa, the 40 mm bore presses bushings into housings on an assembly line, the TPU bumper softening each bottom-out at 30-500 mm/s.
Lift-and-lower gate on a packaging line
The rod lifts about 32 kg vertically with a 2:1 margin, raising a divertor gate on a carton conveyor; FA flange mounting drops it into the existing guard bracket.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X90-10 the Right Cylinder?
Between bores: a 32 mm ACEJ gives 402.1 N push at 0.5 MPa, while a 50 mm bore reaches 981.7 N - pick this 40 mm model when your clamp or press load sits near 380-600 N. The stop screw is a mechanical end stop for the extend stroke only, not a mid-stroke lock, so on air loss the piston still drifts. FA flange or LB foot mounts plus I and Y rod knuckles bolt to the ISO 21287 face; order the -S code if you later need CMSE / DMSE position sensing.
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 ACEJ40X90-10 FAQ
At 0.5 MPa it pushes 628.3 N and pulls 571.8 N; at 0.7 MPa, 879.6 N push and 800.5 N pull; theoretical maximum is 128.1 kgf at 1.0 MPa. The -10 code sets a 10 mm adjustment window: an external stop screw shortens the 90 mm extend stroke to any length from 80 to 90 mm. It is a mechanical end stop only - it never holds a load on air loss.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight guards and gantries. It has a hard-anodized aluminium body, S45C hard-chrome rod, fixed TPU bumpers both ends, a 1/8" PT port and M8x1.25 female rod thread. Sensors need the optional -S magnet (not fitted on this model); with -S, CMSE / DMSE switches mount in the body slots. Operating range is 0.15-1.0 MPa (22-145 psi), -20 to +70 C.
