About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-40
A double acting ISO 21287 compact cylinder, the ACEJ63X60-40 pairs a 63 mm bore with a 60 mm stroke that an external stop screw can trim anywhere in a 40 mm window, giving a usable extend range of 20-60 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 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight clamping fixtures and gantry frames.
Plan on roughly 935 N of real work at 0.5 MPa (about 0.6 of the push rating), which is a vertical lift of about 95 kg - halve that to roughly 47 kg for a 2:1 margin when raising tooling or workpieces. The hard-anodized aluminium body carries a 16 mm S45C hard-chrome rod with an M10x1.5 female thread, and 1/8" ports feed air filtered to 40 um. Note the stop screw is a mechanical end stop only: on air loss the piston drifts, so it never holds a load. If you need position sensing, order the optional -S magnet version for CMSE / DMSE switches - this standard code has no magnet fitted.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-40 Is Used
Fixture clamping on CNC machining centres
Trims the 60 mm extend stroke down to the exact clamp point on aluminium jigs, delivering about 935 N of usable clamp force at 0.5 MPa without shimming spacers.
Stop-and-block stations on bottling lines
The 20-60 mm adjustable range sets bottle stopper height on the line, while the compact body fits the narrow guard space beside a 400 mm conveyor frame.
Pallet gate lift on warehouse diverters
Lifts about 47 kg gate arms vertically with a 2:1 margin, and the LB foot mount bolts straight to the diverter base plate.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-40 the Right Cylinder?
At 1558.6 N push at 0.5 MPa this bore covers medium-duty clamping and pressing. Step down to the 50 mm bore (981.7 N) for lighter jigs, or up to the 80 mm bore (2513.3 N) when the load grows. The 40 mm adjustment window suits stations where the exact stop position is tuned on the machine, not on paper. Bolt it on with FA flange or LB foot mounts, add I or Y rod knuckles for swivelling links, and remember the -S code if CMSE / DMSE switch sensing is planned later.
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 ACEJ63X60-40 FAQ
Push is 1558.6 N and pull 1458.1 N at 0.5 MPa; 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 60 mm extend stroke by up to 40 mm, so the working range is 20-60 mm. It shortens only - it never extends past the ordered stroke, and it is an end stop, not a mid-stroke lock, so the rod still drifts if air is lost. Speed range is 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome 16 mm rod, M10x1.5 female rod thread, 1/8" ports and a fixed TPU bumper at both ends. Position sensing requires the optional -S magnet code, which enables CMSE / DMSE switches; this model without -S has no magnet. Mounting options include FA flange, LB foot, FTC brackets and I/Y rod knuckles on the standard ISO 21287 face.
