About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-20
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ63X80-20 pairs a 63 mm bore with an 80 mm stroke that an external stop screw trims by up to 20 mm on site, giving a usable 60-80 mm range. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight gantries and fixtures where a full-length body will not fit.
For sizing, plan on roughly 935 N of real work at 0.5 MPa (about 0.6 of the push rating) - in lift terms that is around 79 kg held vertically with a 2:1 margin. The hard-anodized aluminium body carries a 16 mm S45C hard-chrome rod with a female M10x1.5 thread, and 1/8" PT ports feed both chambers. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the optional -S magnet lets you add CMSE / DMSE switches; without it no sensor can be fitted.

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 ACEJ63X80-20 Is Used
CNC fixture clamping
The 1558.6 N push at 0.5 MPa secures steel housings in machining fixtures, and the 60-80 mm trim lets one cylinder serve several part heights without re-plumbing.
Pallet gate actuation
Short-body mounting saves about 50% of the length of an ISO 15552 profile cylinder, so the 63 mm bore swings conveyor gates in tight warehouse lanes at up to 500 mm/s.
Press-fit ejection
With about 79 kg of vertical lift capacity at a 2:1 margin, the 80 mm stroke ejects finished castings from die stations on packaging and assembly lines.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-20 the Right Cylinder?
At 63 mm this sits in the mid-heavy class: step down to a 50 mm bore (981.7 N push at 0.5 MPa) for lighter clamping, or up to 80 mm (2513.3 N) when the load demands more. The stop screw is a mechanical end stop for the extend stroke only - on air loss the piston still drifts, so add a separate valve or lock if you need position holding. FA flange and LB foot mountings bolt to the standard ISO 21287 face, and ordering the -S code enables the magnet for CMSE / DMSE switches. Speed range 30-500 mm/s, air pressure 0.15-1.0 MPa (22-145 psi).
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 ACEJ63X80-20 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 -20 code sets a 20 mm adjustment window: an external stop screw shortens the 80 mm extend stroke to any point down to 60 mm. It is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost.
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 fixed TPU bumper at both ends and FA flange or LB foot options on the standard face. Position sensing requires the optional -S magnet code: with it, CMSE / DMSE switches mount in the body slots; without -S there is no magnet and no switch can be read.
