About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-20
The ACEJ63X75-20 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. Its 63 mm bore delivers 1558.6 N push and 1458.1 N pull at 0.5 MPa, rising to 2182.1 N push at 0.7 MPa, with a theoretical peak of 317.9 kgf at 1.0 MPa. An external stop screw trims the 75 mm stroke by up to 20 mm on site, giving a usable extend range of 55-75 mm without changing the cylinder.
The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight clamping fixtures and gantry frames. As a rule of thumb, plan on roughly 935 N of real work at 0.5 MPa, which lifts about 79 kg vertically with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke impact, and the optional -S magnet enables CMSE / DMSE switch sensing.

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 ACEJ63X75-20 Is Used
Press-fit clamping of aluminium housings
The 1558.6 N push at 0.5 MPa seats die-cast gearbox housings into assembly jigs, and the 55-75 mm adjustable range lets one cylinder serve two housing heights.
Pallet stop and index on conveyor lines
With about 79 kg of vertical lift capacity at a 2:1 margin, the 63 mm bore raises and lowers stop gates for 40 kg pallet totes at 30-500 mm/s.
Short-stroke eject on CNC fixtures
The compact body fits inside machine-tool guards where a full-length profile cylinder cannot, trimming the 75 mm stroke down to 55 mm for chip-clearing eject moves.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-20 the Right Cylinder?
At 1558.6 N push at 0.5 MPa this 63 mm bore sits between the 50 mm (981.7 N) and 80 mm (2513.3 N) sizes; step down for lighter clamps or up when the load approaches 935 N of continuous work. The stop screw only shortens the extend stroke and is not a mid-stroke lock, so on air loss the rod still drifts - add a separate holding valve if the load must stay put. FA flange and LB foot mountings bolt to the ISO 21287 face, and the female M10x1.5 rod thread accepts standard I or Y knuckles. Order the -S code if CMSE / DMSE switches are needed.
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 ACEJ63X75-20 FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa it pushes 2182.1 N and pulls 2041.3 N, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -20 code is a 20 mm adjustment window: an external stop screw shortens the 75 mm extend stroke to any value from 55 to 75 mm. It is a mechanical end stop only - it never holds a load against air loss.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium barrel, S45C hard-chrome rod and fixed TPU bumpers at both ends. FA flange and LB foot mountings plus I/Y rod knuckles fit the standard face. Sensing requires the optional -S magnet code; without it no CMSE or DMSE switch can be mounted. Operating range is 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, -20 to +70 C, 1/8" PT ports.
