About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-75S
The ACEJ63X80-75S is a double acting ISO 21287 compact cylinder with a 63 mm bore and an adjustable extend stroke. An external stop screw trims the 80 mm stroke by up to 75 mm, giving a usable range of 5-80 mm, so one unit covers several fixture positions without swapping cylinders. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N 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, which matters in tight gantries and guarding. A hard-anodized aluminium body carries an S45C hard-chrome plated 16 mm rod, with a fixed TPU bumper at each end. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted anywhere along the body slots. As a rule of thumb, plan on roughly 935 N of usable work at 0.5 MPa (about 60% of the push rating), which lifts around 47 kg vertically - halve that to about 24 kg for a 2:1 margin on real part weights.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-75S Is Used
Press-fit station trimming
On an automotive bracket press fixture, the stop screw dials the 80 mm stroke down to the exact insertion depth per part number, with 1558.6 N of push at 0.5 MPa seating bearings without a cylinder change.
Pallet elevator stops
In a packaging line lift, the 63 mm bore raises about 47 kg of palletized product vertically at 0.5 MPa, and the fitted -S magnet with a DMSE switch signals top-of-travel for the transfer conveyor.
Clamp-and-locate jig
A machining-centre jig uses the 5-80 mm adjustable range to clamp different casting heights in one fixture, with the compact body fitting inside guarding that would not accept a full-length ISO 15552 profile cylinder.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-75S the Right Cylinder?
At 63 mm bore this sits in the mid-heavy class: a 50 mm bore delivers 981.7 N push at 0.5 MPa, while an 80 mm bore reaches 2513.3 N, so pick 63 mm when your load falls between roughly 100 kg and 250 kg equivalents. Remember the stop screw is a mechanical end stop only - on air loss the piston still drifts, so it is not a load-holding brake. FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face, and the fitted -S magnet lets CMSE / DMSE switches report end positions. Air supply: 0.15-1.0 MPa (22-145 psi), filtered to 40 um, speed 30-500 mm/s.
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 ACEJ63X80-75S FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa those rise to 2182.1 N and 2041.3 N, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -75 code is a 75 mm adjustment window: an external stop screw shortens the 80 mm extend stroke by up to 75 mm, so the usable range is 5-80 mm. It shortens the stroke only - it never extends it past 80 mm, and it is a mechanical end stop, not a mid-stroke lock or brake.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight jigs and guarding. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be slid into the body slots for position signals (without -S there is no magnet). FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to the standard face. The rod end is female M10x1.5, the port is 1/8" PT, and a fixed TPU bumper decelerates the piston at each end. Operating range is 0.15-1.0 MPa (22-145 psi), -20 to +70 C, speed 30-500 mm/s.
