About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-75S
The ACEJ63X90-75S is a double acting AirTAC compact cylinder to ISO 21287 with an adjustable extend stroke. An external stop screw trims the 90 mm stroke by up to 75 mm, giving a usable range of 15-90 mm on site without swapping the cylinder. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa. A practical rule of thumb is that about 60% of the push force does real work, so plan on roughly 935 N, which lifts about 95 kg vertically - or about 47 kg with a 2:1 margin.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight machine frames and gantries. The hard-anodized aluminium body carries a 16 mm S45C hard-chrome rod, a fixed TPU bumper sits at each end, and because this model carries the -S option the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted anywhere along the body slots. Ports are 1/8" PT.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-75S Is Used
CNC fixture clamping
Clamps aluminium housings in a machining fixture where the 15-90 mm trim range absorbs fixture tolerance, with 1558.6 N push at 0.5 MPa holding the part against the stop.
Packaging line pusher
Pushes cartons off a conveyor into a lane; the short ISO 21287 body fits under the guard rail, and the fitted magnet with a CMSE switch confirms the retracted home position.
Pallet gate actuator
Swings or lifts a pallet-line gate weighing up to about 47 kg vertically with a 2:1 margin, using LB foot mounting and the 90 mm extend stroke trimmed as the line layout demands.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-75S the Right Cylinder?
Size both ways before ordering: a 50 mm bore gives 981.7 N push at 0.5 MPa, while an 80 mm bore reaches 2513.3 N, so the 63 mm sits squarely between them at 1558.6 N. If your job needs the full 250 mm standard stroke of this bore, order a fixed-stroke ACE instead - the -75 window here caps the extend stroke at 90 mm. The stop screw is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA flange or LB foot mountings bolt to the ISO 21287 face, and the fitted -S magnet lets you add CMSE / DMSE switches for end-position sensing.
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 ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-75S FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa push rises to 2182.1 N; theoretical maximum is 317.9 kgf at 1.0 MPa. The -75 code is a 75 mm adjustment window: an external stop screw shortens the 90 mm extend stroke by up to 75 mm, so the usable range is 15-90 mm. It shortens the stroke only - it never extends past 90 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the bore 63 port is 1/8" PT.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight jigs and machine frames. A fixed TPU bumper at each end absorbs end-of-stroke energy; it decelerates only at the ends and never locks or holds a load. FA flange and LB foot mountings bolt straight to the ISO 21287 face. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be slid into the body slots for position sensing.
