About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-50S
The ACEJ63X80-50S 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 50 mm on site, giving a usable range of 30-80 mm without changing the cylinder. At 0.5 MPa the 63 mm bore delivers 1558.6 N on the push stroke and 1458.1 N on the pull stroke, rising to 2182.1 N push 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 machine frames where a full-length profile cylinder will not fit.
Because this model carries the -S code, the magnet is fitted and CMSE / DMSE reed or solid-state switches can be mounted anywhere along the body slots. The hard-anodized aluminium body pairs with an S45C hard-chrome-plated 16 mm rod and a female M10x1.5 rod thread, and a fixed TPU bumper at each end absorbs end-of-stroke energy. In practice, plan for roughly 935 N of real work at 0.5 MPa, which lifts about 79 kg vertically with a 2:1 margin.

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 ACEJ63X80-50S Is Used
Weld fixture clamping
The 1558.6 N push force at 0.5 MPa clamps steel brackets in automotive weld jigs, and the 30-80 mm trim range adapts one cylinder to different part heights.
Case press-down station
On carton-sealing lines the 80 mm stroke presses flaps before taping; the fitted magnet and CMSE switches confirm full down position to the PLC.
Small-parts ejection
Machined housings are pushed off a fixture nest with about 935 N of usable force, and the compact body fits the shallow space under the nest plate.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-50S the Right Cylinder?
Size both ways before committing: the 50 mm bore pushes 981.7 N at 0.5 MPa, while the 80 mm bore reaches 2513.3 N, so the 63 mm bore sits squarely in the mid-force band for clamping and pressing jigs. If the fixture needs a longer reach, bore 63 accepts a standard stroke up to 250 mm. FA flange or LB foot mounts bolt straight to the ISO 21287 face, and the fitted magnet lets CMSE / DMSE switches report end positions. Remember the stop screw is a mechanical end stop only - on air loss the piston still drifts, so do not rely on it to hold a load mid-stroke.
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 ACEJ63X80-50S FAQ
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 push and 2041.3 N pull, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -50 code sets a 50 mm adjustment window: an external stop screw shortens the 80 mm extend stroke by up to 50 mm, so the working range is 30-80 mm. It runs double acting on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), with speed 30-500 mm/s and a 1/8" PT port.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which frees space in guarded or gantry-mounted fixtures. This model includes the optional -S magnet, so CMSE / DMSE reed or solid-state switches clip into the body slots for end-position sensing. Mounting options include FA flange and LB foot, plus I and Y rod knuckles. A fixed TPU bumper at each end absorbs end-of-stroke energy; it does not lock or hold a load.
