About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-75
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ63X75-75 uses a 63 mm bore and a 75 mm nominal stroke that an external stop screw can trim anywhere in a 0-75 mm window. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa. The hard-anodized aluminium body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, so it slots into tight fixtures where a full-length body cannot.
Practically, treat roughly 935 N (about 0.6 of the push figure) as the working force at 0.5 MPa, which corresponds to lifting around 95 kg vertically - halve that to roughly 48 kg if you want a 2:1 margin on a real part. The 16 mm hard-chrome-plated S45C rod carries a female M10x1.5 thread, the air port is 1/8", and fixed TPU bumpers at both ends absorb end-of-stroke shock. Note that this unit has no magnet fitted; the optional -S code adds one for CMSE / DMSE switches.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-75 Is Used
Clamping welded steel brackets
The 1558.6 N push at 0.5 MPa clamps automotive subframe brackets in a machining fixture, and the 0-75 mm adjustment handles two bracket heights on one jig.
Pressing bushings into housings
With about 935 N of usable working force at 0.5 MPa, the cylinder presses bronze bushings into pump housings on a small assembly press.
Diverting cartons on a packaging line
The short ISO 21287 body mounts under guard rails where a full-length profile cylinder will not fit, pushing cartons across a transfer with the stroke trimmed per SKU.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-75 the Right Cylinder?
At 63 mm bore this sits in the mid-heavy class: a 50 mm bore gives 981.7 N push at 0.5 MPa, while an 80 mm bore delivers 2513.3 N, so choose 63 mm when your load falls between roughly 100 and 250 kg. The -75 window means the extend stroke can be set anywhere from 0 to 75 mm on site - useful when one cylinder serves several product sizes. The stop screw is a mechanical end stop only: on air loss the piston drifts, so it is not a mid-stroke lock. FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face; order the -S code if you need 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 ACEJ63X75-75 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 nominal stroke is 75 mm and the -75 stop screw trims the extend stroke anywhere from 0 to 75 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, air port 1/8", rod thread female M10x1.5, and the maximum standard stroke for this bore is 250 mm.
The hard-anodized aluminium ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with fixed TPU bumpers at both ends absorbing end-of-stroke energy. Sensing is not included by default: this model has no magnet, so no switch can be read. Order the -S version to get the optional magnet, which accepts CMSE / DMSE switches. FA flange, LB foot and FTC brackets plus I/Y knuckles mount directly on the ISO 21287 face.
