About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-10
The ACEJ63X90-10 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 90 mm stroke by up to 10 mm on site, giving a usable range of 80-90 mm without changing hardware. At 0.5 MPa the 63 mm bore delivers 1558.6 N on the push stroke and 1458.1 N on the pull stroke, rising to 2182.1 N push at 0.7 MPa, with a theoretical maximum of 317.9 kgf at 1.0 MPa.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight clamping fixtures and machine frames. As a rule of thumb, plan for roughly 935 N of real work at 0.5 MPa, which corresponds to lifting about 79 kg vertically, or roughly 40 kg with a 2:1 margin. The hard-anodized aluminium body carries an S45C hard-chrome-plated 16 mm rod, and a fixed TPU bumper at each end absorbs end-of-stroke energy. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-10 Is Used
Weldment clamp fixtures
Clamps steel brackets on an automotive subframe jig; the 80-90 mm adjustable window lets the setter dial in clamp travel per fixture without swapping cylinders.
Case packer push-off
Pushes filled cartons off a conveyor lane into a packer infeed; 1558.6 N at 0.5 MPa moves loaded cases quickly across the 90 mm stroke.
Press nip ejection
Ejects stamped parts from a small press die; the short ISO 21287 body fits the shallow die space where a full-length profile cylinder would not.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-10 the Right Cylinder?
At 1558.6 N push at 0.5 MPa this 63 mm bore sits between the 50 mm bore (981.7 N) and the 80 mm bore (2513.3 N), so choose the 50 mm for lighter clamps and the 80 mm when you need over 2.5 kN. The -10 stop screw only shortens the extend stroke within the ordered window and is a mechanical end stop, not a mid-stroke lock: on air loss the piston still drifts, so add a separate holding valve if the load must stay put. FA flange or LB foot mounts bolt to the ISO 21287 face, and if you need position sensing, order the -S variant so CMSE / DMSE switches can be fitted; this model has no magnet.
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 ACEJ63X90-10 FAQ
At 0.5 MPa it pushes with 1558.6 N and pulls with 1458.1 N; at 0.7 MPa push is 2182.1 N and pull is 2041.3 N. The theoretical maximum is 317.9 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C.
An external stop screw shortens the 90 mm extend stroke by up to 10 mm, so the working range is 80-90 mm; it cannot lengthen the stroke beyond 90 mm. The stop is an end stop only and never holds a load on air loss. This unit has no magnet, so no switch can be mounted; order the -S code for the optional magnet that accepts CMSE / DMSE switches. Mounting options include FA flange and LB foot, and the fixed TPU bumpers absorb end-of-stroke energy.
