About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X75-50S
The ACEJ32X75-50S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. Its 32 mm bore delivers 402.1 N push and 345.6 N pull at 0.5 MPa, rising to 563 N at 0.7 MPa, with a theoretical peak of 82 kgf at 1.0 MPa. An external stop screw trims the 75 mm stroke by up to 50 mm on site, giving a usable extend range of 25-75 mm without changing the cylinder.
The short ISO 21287 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. The hard-anodized aluminium body carries an S45C hard-chrome rod, and fixed TPU bumpers absorb end-of-stroke shock. As an -S model the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be clamped straight onto the body. For sizing, treat roughly 240 N (about 0.6 of the push force) as the practical working effort at 0.5 MPa, which corresponds to lifting about 24 kg vertically - halve that to roughly 12 kg if you want a 2:1 margin on a vertical lift.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X75-50S Is Used
Fixture clamping with trimmed stroke
Clamps aluminum die-cast housings on a machining fixture where the 25-75 mm adjustable range lets one cylinder serve several part heights; 402.1 N push at 0.5 MPa holds the part against the locators.
Packaging line pusher
Pushes cartons sideways off a conveyor into a lane diverter; the compact body fits under low guarding, and the fitted magnet with a DMSE switch confirms full retract before the next cycle.
Small parts press-fit station
Presses bearings into plastic pump housings on an assembly bench, using about 240 N of practical working force at 0.5 MPa; the stop screw sets the exact bottom-of-stroke depth per part.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X75-50S the Right Cylinder?
At 32 mm bore this sits in the mid light-duty band: a 25 mm bore gives 245.4 N push at 0.5 MPa if the load is lighter, while a 40 mm bore raises it to 628.3 N for heavier clamping. The stop screw is a mechanical end stop for the extend stroke only - it does not lock the piston mid-stroke, so on air loss the rod can still drift; add a separate holding valve if the load must stay put. FA flange or LB foot mounts bolt to the ISO 21287 face, and the fitted -S magnet lets CMSE / DMSE switches report end positions. Air supply: 0.15-1.0 MPa (22-145 psi), filtered to 40 um, speed 30-500 mm/s.
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 ACEJ32X75-50S 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 -50 code sets a 50 mm adjustment window: an external stop screw shortens the 75 mm extend stroke by up to 50 mm, so the working range is 25-75 mm. It is double acting, runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, at 30-500 mm/s, with a 1/8" port and female M8x1.25 rod thread.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits shallow fixtures and guarded gantries. This -S version carries the optional magnet, so CMSE / DMSE reed or solid-state switches clamp onto the body slots for end-position sensing. FA flange and LB foot mounts fit the standard ISO 21287 face, and fixed TPU bumpers at both ends absorb end-of-stroke impact.
