About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-50
A double acting ISO 21287 compact cylinder, the ACEJ63X90-50 pairs a 63 mm bore with a 90 mm stroke that can be trimmed on site by up to 50 mm using the external stop screw, giving a usable extend range of 40-90 mm. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa those figures rise to 2182.1 N and 2041.3 N, with a theoretical ceiling of 317.9 kgf at 1.0 MPa. The hard-anodized aluminium body carries a hard-chrome plated S45C rod with a female M10x1.5 thread, and air is fed through a 1/8" PT port.
Because the short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this bore-63 unit slots into tight presses, clamping fixtures and gantry frames where a full-length cylinder cannot reach. As a practical sizing guide, plan on roughly 935 N (about 95 kg) of real work at 0.5 MPa, which corresponds to lifting around 79 kg vertically with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke impact, and the optional -S magnet code enables CMSE / DMSE switch sensing - without that code no magnet is fitted. FA flange and LB foot mounts bolt straight to the ISO 21287 face.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-50 Is Used
Pneumatic press station
The 1558.6 N push at 0.5 MPa suits a bench-top crimping or staking press on an electronics assembly line, with the 50 mm window letting the operator dial the extend stroke between 40 and 90 mm per product change.
Machining fixture clamping
On a CNC fixture plate, the short ISO 21287 body tucks under a guard where an ISO 15552 profile cylinder would overhang, and the FA flange bolts directly to the standard mounting face.
Pallet gate actuation
In a warehouse line gate or stopper, the 63 mm bore swings or lifts a light gate arm - about 79 kg vertical lift with a 2:1 margin - while the LB foot mount anchors to the conveyor frame.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-50 the Right Cylinder?
For a 90 mm stroke in this force band, the 63 mm bore is the balanced pick: 1558.6 N push at 0.5 MPa covers most clamping and pressing jigs. Step down to a 50 mm bore (981.7 N push at 0.5 MPa) if the load is lighter and space is tighter, or up to an 80 mm bore (2513.3 N push at 0.5 MPa) for heavier presses. If the -50 window is trimmed below 90 mm, remember the stop screw is a mechanical end stop only - on air loss the piston can still drift, so do not rely on it to hold a load. Match FA flange or LB foot mounting to your fixture, and add the -S code if CMSE / DMSE position switches are planned.
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 ACEJ63X90-50 FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa push is 2182.1 N and pull 2041.3 N; theoretical maximum is 317.9 kgf at 1.0 MPa. The -50 code is a 50 mm adjustment window: an external stop screw shortens the 90 mm extend stroke on site, so the usable range is 40-90 mm. It shortens only - it never extends past the ordered stroke. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow jigs and guarded frames. A fixed TPU bumper at each end absorbs end-of-stroke impact. Sensing requires the optional -S magnet code, which allows CMSE / DMSE switches on the body slots - this model has no magnet fitted, so no switch can be read without ordering -S. FA flange and LB foot mounts attach to the standard ISO 21287 face.
