About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-75SB
The ACEJ63X75-75SB 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. The external stop screw trims the 75 mm extend stroke anywhere in the ordered 0-75 mm window, so one cylinder covers several fixture positions. The male rod thread (B code) and the fitted -S magnet for CMSE / DMSE switches are already on this model.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters inside gantries and guarding where every millimetre counts. A hard-anodized aluminium body carries a hard-chrome S45C rod, and fixed TPU bumpers absorb end-of-stroke shock at both ends. As a rule of thumb, plan on roughly 935 N (about 95 kg) of usable push at 0.5 MPa, which lifts around 79 kg vertically even after halving for a 2:1 margin. Speed range is 30-500 mm/s across 0.15-1.0 MPa (22-145 psi).

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 ACEJ63X75-75SB Is Used
Weld fixture clamping
The 1558.6 N push at 0.5 MPa clamps steel brackets in automotive weld jigs, while the 0-75 mm adjustable window lets one cylinder serve different part heights.
Press-fit insertion
Around 935 N of practical working force seats bearings and bushings into aluminium housings on small assembly presses, with the male rod thread simplifying tooling attachment.
Packaging line diverting
Mounted under a conveyor, the compact short body fits between rails to push cartons onto a lane, and the fitted magnet with a DMSE switch confirms each divert.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-75SB the Right Cylinder?
At 63 mm bore this sits between the 50 mm size (981.7 N push at 0.5 MPa) and the 80 mm size (2513.3 N push at 0.5 MPa), so pick 63 mm when a 50 mm cylinder is marginal but 80 mm is oversized. The 75 mm stroke is well inside the 250 mm maximum standard stroke for this bore. Remember the stop screw only shortens the extend stroke and is not a mid-stroke lock: on air loss the piston can still drift, so add a separate valve or clamp where a load must be held. FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face; the -S magnet on this unit accepts 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 ACEJ63X75-75SB 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; the theoretical maximum is 317.9 kgf at 1.0 MPa. The -75 code is a 75 mm adjustment window: an external stop screw shortens the 75 mm extend stroke to any position down to 0 mm, so the usable range is 0-75 mm. It shortens the stroke only and never lengthens it past 75 mm. The stop is a mechanical end stop, not a load-holding brake.
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, hard-chrome S45C rod and fixed TPU bumpers at both ends. The S means the optional -S magnet is fitted on this model, so CMSE / DMSE reed or solid-state switches can be mounted in the body slots for position feedback. Ports are 1/8" (bore 63), the rod thread is male (B code), and FA/LB/FTC mountings plus I/Y knuckles bolt straight to the ISO 21287 face.
