About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X100-40S
The ACEJ40X100-40S is a double acting, adjustable-stroke compact cylinder built to ISO 21287. Its 40 mm bore delivers 628.3 N push and 571.8 N pull at 0.5 MPa, rising to 879.6 N push at 0.7 MPa, with a theoretical peak of 128.1 kgf at 1.0 MPa. The -40 code adds a 40 mm adjustment window: an external stop screw trims the extend stroke anywhere between 60 and 100 mm on site, so one cylinder serves several jig depths without reordering. The short ISO 21287 body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight guarding and gantry frames.
Practical sizing: at 0.5 MPa the push force converts to about 64 kgf, so plan on roughly 38 kg of usable vertical lift with a 2:1 margin. The hard-anodized aluminium body carries a hard-chromed S45C rod, fixed TPU bumpers at both ends, and this model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke sensing. Air supply is 0.15-1.0 MPa (22-145 psi) filtered to 40 um, speed range 30-500 mm/s, temperature -20 to +70 C.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X100-40S Is Used
Fixture clamping on CNC pallets
A 60-100 mm adjustable extend stroke lets one cylinder clamp different pallet heights by turning the stop screw instead of swapping cylinders, with 628.3 N of push at 0.5 MPa holding parts firmly.
Packaging line push-off stations
The short ISO 21287 body fits inside tight conveyor guarding, and the fitted -S magnet with a DMSE switch confirms each 100 mm push of cartons into the transfer chute.
Lab press and sample positioning
About 38 kg of practical vertical lift at 0.5 MPa suits light sample pressing and lift-and-place motions, with the 40 mm window letting technicians fine-tune stroke depth per test recipe.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X100-40S the Right Cylinder?
At 40 mm bore this sits in the mid-thrust band: a 32 mm bore gives 402.1 N push at 0.5 MPa, while a 50 mm bore raises it to 981.7 N, so step up if your fixture needs more than about 380 N of working force. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the rod still drifts, so add a separate holding valve where a load must stay put. Mounting is via FA flange or LB foot on the ISO 21287 face, with I and Y rod knuckles available; the female M8x1.25 rod thread suits standard rod-eye accessories. If you need position feedback, this unit already carries the -S magnet for 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 ACEJ40X100-40S FAQ
At 0.5 MPa it pushes 628.3 N and pulls 571.8 N; at 0.7 MPa push is 879.6 N. Theoretical maximum is 128.1 kgf at 1.0 MPa. It is double acting with an adjustable extend stroke: the -40 stop screw trims the 100 mm stroke down to 60 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, port 1/8" PT, rod thread female M8x1.25.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow fixtures and guarded frames. Fixed TPU bumpers absorb end-of-stroke energy at both ends. FA flange and LB foot mountings bolt to the standard face. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches mount directly in the body slots for extend and retract signals.
