About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-10SB
A double acting ISO 21287 compact cylinder, the ACEJ63X55-10SB pairs a 63 mm bore with a 55 mm stroke that an external stop screw trims by up to 10 mm, giving a usable extend range of 45-55 mm. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa. The male rod thread (B code) suits tooling that bolts onto the rod, and the fitted -S magnet accepts CMSE / DMSE switches for end-of-stroke sensing.
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 machine frames. As a rule of thumb, plan on about 935 N of real work at 0.5 MPa (roughly 0.6 of the push rating), which lifts about 79 kg vertically with a 2:1 margin. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper 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 ACEJ63X55-10SB Is Used
Press-fit bushing insertion
The 1558.6 N push at 0.5 MPa presses bearings and bushings into pump housings, while the 45-55 mm trim range matches varying part heights on the same fixture.
Pallet strapper actuation
End-of-line strapping heads need a short, powerful clamp stroke; the compact body fits the strapper frame where a full-length profile cylinder cannot.
Gated conveyor diverter
With the fitted -S magnet and CMSE switches, the 55 mm stroke flips product guide gates between two lanes, and the stop screw fine-tunes gate travel on site.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-10SB the Right Cylinder?
At this force class the 63 mm bore sits between the 50 mm bore (981.7 N push at 0.5 MPa) and the 80 mm bore (2513.3 N push at 0.5 MPa), so pick 63 mm when 50 mm is marginal but 80 mm is oversized. The 10 mm adjustment window only shortens the extend stroke to a mechanical end stop; it is not a mid-stroke lock, so on air loss the piston still drifts. FA flange or LB foot mountings bolt to the ISO 21287 face, and the fitted -S magnet lets CMSE / DMSE switches report position.
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 ACEJ63X55-10SB 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. The theoretical maximum is 317.9 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with proof pressure 1.5 MPa (215 psi), running at 30-500 mm/s on air filtered to 40 um.
The -10 code sets a 10 mm window: an external stop screw shortens the 55 mm extend stroke anywhere down to 45 mm, and a fixed TPU bumper decelerates the piston at each end. The -S magnet is fitted on this model, so CMSE / DMSE reed or solid-state switches can be clamped into the body slots for position feedback.
