About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-40
The ACEJ63X90-40 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 40 mm on site, giving a usable range of 50-90 mm without changing the cylinder. At 0.5 MPa the 63 mm bore delivers 1558.6 N on the extend stroke and 1458.1 N on retract, rising to 2182.1 N at 0.7 MPa. In practice, plan on roughly 935 N (about 95 kg) of usable working force at 0.5 MPa, and expect it to lift about 79 kg vertically 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 clamping fixtures. A hard-anodized aluminium body carries an S45C hard-chrome plated 16 mm rod, fixed TPU bumpers absorb end-of-stroke energy at both ends, and FA flange or LB foot mounts plus I/Y rod knuckles bolt straight to the standard face. Speed range is 30-500 mm/s.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-40 Is Used
Pneumatic press for aluminum bracket riveting
The 1558.6 N extend force at 0.5 MPa seats rivets in aluminum brackets, and the 40 mm trim window lets the line technician shorten the stroke to 50 mm when a thinner part variant runs.
Clamping fixture on a CNC machining pallet
Roughly 95 kg of usable clamping force holds steel housings against a CNC fixture, and the compact body fits inside the pallet guard where a full-length profile cylinder would not.
Vertical lift in a battery pack assembly cell
With a 2:1 margin the cylinder lifts about 79 kg vertically, raising lithium-ion module fixtures between assembly stations at up to 500 mm/s.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-40 the Right Cylinder?
Size against the load: at 0.5 MPa the next bore down, ACEJ50, pushes 981.7 N, while the ACEJ80 above it pushes 2513.3 N - so pick the 63 mm when your clamping or pressing force sits between roughly 950 and 1550 N. If the application needs a shorter stroke, the 40 mm window lets you dial the extend stroke anywhere from 50 to 90 mm; note the stop screw is a mechanical end stop only, so the piston will still drift if air is lost. Order the -S code if you later want CMSE / DMSE switches, and choose FA flange, LB foot or I/Y knuckles to match the fixture.
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 ACEJ63X90-40 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, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -40 code is a 40 mm adjustment window: an external stop screw shortens the 90 mm extend stroke by up to 40 mm, so the working range is 50-90 mm. The stop is a mechanical end stop, not a mid-stroke lock - on air loss the piston still drifts. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, a 16 mm hard-chrome plated S45C rod and fixed TPU bumpers at both ends. FA flange, LB foot and I/Y rod knuckles bolt to the standard face. Position sensing requires the optional -S magnet code: without -S there is no magnet and no CMSE / DMSE switch can be mounted, so order the -S variant if switch feedback is needed.
