About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-75SB
The ACEJ63X80-75SB is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: a 63 mm bore drives an 80 mm stroke that the external stop screw can trim anywhere in the ordered 75 mm window, giving a usable range of 5-80 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 B code gives a male rod thread on the 16 mm S45C hard-chrome rod.
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 fixture plates. A practical sizing rule: keep real work near 935 N (about 0.6 of the push force), which corresponds to lifting roughly 79 kg vertically with a 2:1 margin. The -S magnet is fitted on this model, so CMSE / DMSE reed or solid-state switches can be mounted in the body slots. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and fixed TPU bumpers sit at both ends.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-75SB Is Used
Clamping on CNC fixtures
The 1558.6 N push at 0.5 MPa holds aluminium housings against CNC fixture locators, and the 5-80 mm trim range lets one cylinder serve several part heights.
Case ejection on packaging lines
Push force near 1558 N ejects filled cartons from a magazine, while the compact body fits inside guarded frames where a full-length profile cylinder cannot.
Small vertical lift stations
With a 2:1 margin the bore lifts about 79 kg vertically, enough for raising pallet-size jigs or gate plates at assembly benches; CMSE switches confirm top position.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-75SB the Right Cylinder?
At this force class the 63 mm bore sits between the 50 mm (981.7 N push at 0.5 MPa) and the 80 mm (2513.3 N push at 0.5 MPa); pick 63 mm when your clamp or press load falls in the 900-1500 N band. Remember the stop screw is an end stop only, not a mid-stroke lock, so the rod still drifts if air is lost. FA flange or LB foot mounts bolt to the ISO 21287 face, and because the -S magnet is fitted you can add CMSE / DMSE switches for end-of-stroke signalling without reordering.
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 ACEJ63X80-75SB FAQ
Push is 1558.6 N and pull 1458.1 N at 0.5 MPa; at 0.7 MPa push reaches 2182.1 N and pull 2041.3 N, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -75 code sets a 75 mm adjustment window: an external stop screw shortens the 80 mm extend stroke on site, so the usable range is 5-80 mm. The stop is a mechanical end stop, not a load-holding brake. 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 and a fixed TPU bumper at each end. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be fitted in the body slots. FA flange and LB foot mounts plus I/Y rod knuckles bolt to the standard ISO 21287 face; the rod end here is male thread and the port is 1/8".
