About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-20S
The ACEJ63X80-20S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 80 mm stroke by up to 20 mm on site, giving a usable 60-80 mm range without changing the cylinder. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa, so it handles mid-size clamping and pressing work in a body that saves about 50% of the mounting length of an ISO 15552 profile cylinder.
Because the stop screw is a mechanical end stop only, the rod still drifts if air is lost - it is not a mid-stroke lock. For sizing, treat roughly 0.6 of the push rating as usable work, about 935 N, which corresponds to lifting roughly 47 kg vertically with a 2:1 margin (about 95 kg at the full 1558.6 N). The -S code on this model means the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted directly in the body slots.

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 ACEJ63X80-20S Is Used
Fixture clamping on CNC machining centres
Around 1558.6 N of push at 0.5 MPa clamps aluminium or steel workpieces in machining fixtures, and the 60-80 mm trim range lets one cylinder serve different part heights.
Press-fit assembly of bearings and bushings
The 2182.1 N push at 0.7 MPa presses small bearings and bushings into housings on electronics and appliance assembly lines where a full-length profile cylinder will not fit.
Vertical lift in palletising gantries
With about 95 kg of vertical-lift equivalent at the full push rating, the 63 mm bore raises cartons or trays in compact gantry pick-and-place heads.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-20S the Right Cylinder?
At 63 mm bore this sits in the upper-middle force class: the 40 mm bore offers 628.3 N push at 0.5 MPa and the 80 mm bore reaches 2513.3 N, so pick 63 when you need roughly 1500 N in a short envelope. If your fixture needs the full 80 mm every cycle with no trimming, the fixed-stroke ACE63X80 does the same job; the -20 adjuster here is for dialling the extend stroke down between 60 and 80 mm. FA flange or LB foot mountings bolt to the ISO 21287 face, and the fitted magnet pairs with CMSE / DMSE switches for end-of-stroke signalling.
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 ACEJ63X80-20S 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 is a 20 mm adjustment window: an external stop screw shortens the 80 mm extend stroke by up to 20 mm, so the working range is 60-80 mm. It shortens the stroke only - it never extends past 80 mm and does not hold a load on air loss.
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, S45C hard-chrome rod and fixed TPU bumpers at both ends. The -S magnet is fitted on this model, so CMSE / DMSE switches can be slotted onto the body. FA flange, LB foot and rod knuckles mount on the standard ISO 21287 face; port is 1/8" PT, rod thread M10x1.5 female, speed 30-500 mm/s, pressure 0.15-1.0 MPa (22-145 psi).
