About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-30
The ACEJ63X75-30 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 75 mm stroke by up to 30 mm on site, giving a usable range of 45-75 mm without changing the cylinder. At 0.5 MPa the 63 mm bore pushes 1558.6 N and pulls 1458.1 N, and the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight clamping fixtures where a full-length body will not fit.
For sizing the job, treat roughly 935 N (about 95 kg of force) as the practical working output at 0.5 MPa, which corresponds to lifting about 79 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries a 16 mm S45C hard-chrome rod, a fixed TPU bumper sits at both ends, and the optional -S magnet enables CMSE / DMSE switches; without the -S code there is no magnet fitted.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-30 Is Used
Clamp fixtures on CNC pallets
The 45-75 mm adjustable window lets one cylinder serve several pallet sizes, and 1558.6 N push at 0.5 MPa clamps steel workpieces firmly on machining centers.
Packaging line pushers
Pushes cartons or trays off a conveyor at 30-500 mm/s, with the short ISO 21287 body fitting under low guard rails where space is tight.
Small press and riveting stations
About 935 N of practical working force at 0.5 MPa suits light staking and riveting of brackets, with the stop screw setting the exact extend position per part.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-30 the Right Cylinder?
At this force class the 63 mm bore delivers 1558.6 N push at 0.5 MPa; step down to the 50 mm bore (981.7 N push at 0.5 MPa) for lighter clamps or up to the 80 mm bore (2513.3 N) when the load grows. Remember the stop screw is a mechanical end stop for the extend stroke only - it does not hold a load if air is lost. FA flange, LB foot and I/Y rod knuckles bolt to the ISO 21287 face, and the 1/8" PT port is fixed by the 63 mm bore. If position feedback is needed, order the -S variant so CMSE / DMSE switches can be mounted.
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 ACEJ63X75-30 FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa push rises to 2182.1 N and pull to 2041.3 N; theoretical maximum is 317.9 kgf at 1.0 MPa. The -30 code is a 30 mm adjustment window: an external stop screw shortens the 75 mm extend stroke by up to 30 mm, so the working range is 45-75 mm. It cannot lengthen the stroke past 75 mm, and the stop is 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.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, 16 mm hard-chrome rod and fixed TPU bumpers at both ends. Position sensing is possible only when you order the optional -S magnet, which allows CMSE / DMSE switches; this model (no S code) has no magnet, so no switch can be mounted. FA flange, LB foot and I/Y knuckles bolt straight to the standard ISO 21287 face.
