About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X50-50S
The ACEJ32X50-50S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 50 mm stroke anywhere in the ordered 0-50 mm window, so one unit covers several fixture positions. At 0.5 MPa it pushes 402.1 N and pulls 345.6 N, and the -S code means the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be clipped onto the body slots for end-of-travel signals.
The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in tight jigs and guarding. Plan on roughly 240 N (about 24 kgf) of usable working force at 0.5 MPa, which is a vertical lift of about 20 kg with a 2:1 margin. FA flange, LB foot and I/Y rod knuckles bolt straight to the ISO 21287 face, and the fixed TPU bumper at both ends absorbs end-of-stroke shock.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 ACEJ32X50-50S Is Used
Fixture clamping on CNC pallets
The 0-50 mm adjustable window lets one cylinder serve different pallet heights, while 402.1 N at 0.5 MPa clamps aluminium fixtures securely.
Packaging line reject pushers
At 30-500 mm/s the rod kicks off-spec cartons off a belt, and the fitted magnet with a CMSE switch confirms the retract position each cycle.
Lab sample press station
About 24 kgf of usable force at 0.5 MPa presses sample trays gently, and the compact body fits inside a benchtop guard where a full-length cylinder will not.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X50-50S the Right Cylinder?
At 402.1 N push at 0.5 MPa this 32 mm bore sits between the 25 mm (245.4 N) and 40 mm (628.3 N) sizes, so step down for lighter clamps or up for heavier presses. The stop screw only shortens the extend stroke and is a mechanical end stop, not a mid-stroke lock: on air loss the piston still drifts, so do not rely on it to hold a load. If you need position feedback, this model already carries the optional -S magnet for CMSE / DMSE switches; FA flange or LB foot mounting drops into standard fixtures.
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 ACEJ32X50-50S 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, with a theoretical maximum of 82 kgf at 1.0 MPa. The -50 code is a 50 mm adjustment window: an external stop screw shortens the 50 mm extend stroke anywhere from 0 to 50 mm, so the usable range is 0-50 mm. It shortens the stroke only; it never lengthens it past 50 mm.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and a fixed TPU bumper at both ends. Because this model carries the optional -S magnet, CMSE / DMSE reed or solid-state switches can be mounted in the body slots. FA flange, LB foot and I/Y rod knuckles attach to the standard ISO 21287 face, and the 1/8" port takes PT threading.
