About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X45-10S
The ACEJ40X45-10S is a double acting ISO 21287 compact cylinder with a 40 mm bore and a 45 mm stroke that can be trimmed on site. The -10 code sets a 10 mm adjustment window, so an external stop screw lets you shorten the extend stroke anywhere between 35 and 45 mm without changing hardware. At 0.5 MPa it pushes 628.3 N and pulls 571.8 N, and the theoretical peak reaches 128.1 kgf at 1.0 MPa. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs, guarding and gantry frames.
Because the -S code is on this unit, the magnet is fitted and CMSE or DMSE reed and solid-state switches can be clamped straight onto the body slots. The hard-anodized aluminium body carries a hard-chromed S45C rod with a female M8x1.25 thread, and fixed TPU bumpers at both ends absorb end-of-stroke shock. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), it cycles at 30-500 mm/s. As a rule of thumb, plan on roughly 377 N of real work at 0.5 MPa, which lifts about 32 kg vertically with a 2:1 margin.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X45-10S Is Used
Fixture clamping on CNC pallets
The 35-45 mm trimmed extend stroke seats clamps against machined pallets without over-travel, and 628.3 N at 0.5 MPa holds steel parts through milling cycles.
Carton push-off on packing lines
A short 45 mm stroke with a 10 mm trim window ejects filled cartons from a conveyor lane, while the fitted magnet and CMSE switch confirm each push completed.
Small-part press fitting
About 377 N of usable force at 0.5 MPa presses bushings into housings on an electronics assembly bench, with the compact body fitting inside the press frame.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X45-10S the Right Cylinder?
Size this 40 mm bore when your load sits between the 32 mm class (402.1 N push at 0.5 MPa) and the 50 mm class (981.7 N push at 0.5 MPa); if your part weighs more than about 32 kg to lift, step up to the 50 mm bore. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the rod still drifts if air is lost. FA flange or LB foot mounts bolt to the ISO 21287 face, and the fitted -S magnet lets you add CMSE / DMSE switches for end-of-stroke signalling. Ports are 1/8" PT on this bore.
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 ACEJ40X45-10S FAQ
At 0.5 MPa it pushes 628.3 N and pulls 571.8 N; at 0.7 MPa those rise to 879.6 N push and 800.5 N pull, with a theoretical maximum of 128.1 kgf at 1.0 MPa. The -10 code gives a 10 mm adjustment window: turn the external stop screw to shorten the 45 mm extend stroke to any length from 35 to 45 mm. The stop is an end stop only, not a load-holding brake, so the rod can drift if air pressure is lost. Speed range is 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, so it fits where a full-length cylinder will not. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches mount in the body slots for position signals. FA flange and LB foot mounts bolt to the standard ISO 21287 face, the rod end is a female M8x1.25 thread, and the air port is 1/8" PT. Fixed TPU bumpers at both ends absorb end-of-stroke impact.
