About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X150-40
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ40X150-40 pairs a 40 mm bore with a 150 mm stroke that an external stop screw trims by up to 40 mm on site, giving a usable range of 110-150 mm. At 0.5 MPa it pushes 628.3 N and pulls 571.8 N, and its 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 will not fit.
Plan on roughly 377 N of real work at 0.5 MPa (about 0.6 of the push force), which equates to lifting about 32 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries a hard-chrome plated S45C rod with a female M8x1.25 thread, fixed TPU bumpers absorb end-of-stroke energy at both ends, and the magnet is the optional -S code - this model has none, so no CMSE or DMSE switch can be fitted unless you order -S.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X150-40 Is Used
Fixture clamping on CNC pallets
The 110-150 mm adjustable window lets one cylinder serve several pallet heights, and 628.3 N at 0.5 MPa clamps steel fixtures firmly without oversizing the envelope.
Carton push-off on packaging lines
Pushing 500 mm cartons off a conveyor at 30-500 mm/s, the compact body fits under low guard rails where an ISO 15552 profile cylinder would overhang the frame.
Lift-and-lower of small die sets
With about 32 kg vertical lift capacity at a 2:1 margin, it raises light die shoes or gauges in press-shop tooling, with the stop screw set to the exact top position.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X150-40 the Right Cylinder?
At 628.3 N push at 0.5 MPa this 40 mm bore sits between the 32 mm (402.1 N) and 50 mm (981.7 N) sizes: step down when your load is under 400 N, step up past 600 N or for higher side loads. The 150 mm stroke is well inside the 200 mm maximum standard stroke for this bore, so it is a catalog item, not a made-to-order build.
Remember the -40 adjuster is a mechanical end stop for the extend stroke only - it shortens travel, it never lengthens it, and on air loss the piston still drifts, so add a valve or external stop if you need position holding. FA flange, LB foot, FTC brackets and I/Y rod knuckles bolt straight to the ISO 21287 face; order the -S code if you want CMSE / DMSE switch capability.
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 ACEJ40X150-40 FAQ
At 0.5 MPa it pushes 628.3 N and pulls 571.8 N; at 0.7 MPa it pushes 879.6 N and pulls 800.5 N; theoretical maximum is 128.1 kgf at 1.0 MPa. The -40 code is a 40 mm adjustment window: an external stop screw shortens the 150 mm extend stroke by up to 40 mm, so usable travel is 110-150 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, air filtered to 40 um.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with fixed TPU bumpers at both ends to absorb end-of-stroke energy. Sensors work only with the optional -S magnet code, which enables CMSE / DMSE switches; this model has no magnet, so order -S if you need switching. FA flange, LB foot, FTC brackets and I/Y rod knuckles mount on the standard ISO 21287 face, and the 1/8" port suits this 40 mm bore.
