About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-40SB
The ACEJ63X90-40SB is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 90 mm stroke by up to 40 mm on site, giving a usable range of 50-90 mm without changing the cylinder. At 0.5 MPa the 63 mm bore delivers 1558.6 N on extend and 1458.1 N on retract, rising to 2182.1 N at 0.7 MPa, with a theoretical peak of 317.9 kgf at 1.0 MPa. The S code means the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be slid into the body slots for end-of-stroke signalling, and the B code gives a male 16 mm rod thread.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in tight gantries and guarding where every millimetre of envelope counts. A hard-anodized aluminium body carries an S45C hard-chrome-plated rod, fixed TPU bumpers absorb end-of-stroke energy at both ends, and the FA flange, LB foot and I/Y rod knuckles bolt straight to the ISO 21287 face. For vertical lifting, plan on roughly 79 kg as a practical lift with a 2:1 margin, since the raw 0.5 MPa push converts to about 159 kgf.

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 ACEJ63X90-40SB Is Used
Jig clamping on CNC fixtures
1558.6 N of push at 0.5 MPa clamps aluminium or steel workpieces in machining jigs, and the 50-90 mm adjustable range lets one cylinder serve several fixture heights.
Push-off stations on packaging lines
The compact body fits beside narrow conveyor frames, kicking cartons or trays off the line at 30-500 mm/s with CMSE switch signalling from the fitted magnet.
Press-fit and staking heads
About 159 kgf of theoretical force at 1.0 MPa suits light press-fit, staking and riveting heads where the 90 mm stroke covers part loading and the stop screw sets the exact bottom position.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-40SB the Right Cylinder?
Size the job against 1558.6 N of push at 0.5 MPa; if your load needs less, the ACEJ50 at 981.7 N is the step down, and the ACEJ80 at 2513.3 N is the step up. Remember the stop screw only shortens the extend stroke within the 40 mm window - it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. Match FA flange or LB foot mounting to your fixture, and keep the -S magnet in mind if position sensing will be added later; this model already carries it.
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 ACEJ63X90-40SB 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; theoretical maximum is 317.9 kgf at 1.0 MPa. It is double acting with a 63 mm bore, 90 mm stroke adjustable down to 50 mm via the -40 stop screw, a 16 mm male rod thread (B code), 1/8" ports, air filtered to 40 um, 0.15-1.0 MPa (22-145 psi) operating pressure, 1.5 MPa (215 psi) proof pressure, -20 to +70 C, and 30-500 mm/s speed.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guards and gantries. Fixed TPU bumpers at both ends absorb end-of-stroke energy. Because the S code is ordered, the magnet is fitted and CMSE / DMSE reed or solid-state switches can be mounted in the body slots; FA flange, LB foot and I/Y rod knuckles bolt directly to the ISO 21287 face.
