About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-30S
The ACEJ63X90-30S is a double acting ISO 21287 compact cylinder with a 63 mm bore and a 90 mm stroke that an external stop screw trims by up to 30 mm, giving a usable extend range of 60-90 mm. 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 sits firmly in the mid-heavy thrust class. The S code means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped onto the body slots for end-of-travel sensing.
Because the short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this 90 mm stroke unit slots into tight machine frames where a full-length body would not fit. For real-world sizing, plan on roughly 935 N of usable push at 0.5 MPa, which is about 95 kg of vertical lift with a 2:1 margin - enough to raise a filled pallet jig or a small die set. A fixed TPU bumper at each end absorbs end-of-stroke shock, and FA flange or LB foot mounts bolt straight to the standard face.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
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 ACEJ63X90-30S Is Used
Pallet-stacker lift assist
With about 95 kg of vertical lift at a 2:1 margin (935 N usable push at 0.5 MPa), the 63 mm bore raises loaded pallet jigs in a warehouse gate while the 60-90 mm trim range matches varying pallet heights.
Die-set ejection on a press bench
Pushing 1558.6 N at 0.5 MPa ejects small stamping dies from a fixture; the stop screw lets the setter shorten the 90 mm stroke to 60 mm for shallow dies without changing hardware.
Packaging line pusher gate
The short ISO 21287 body fits under conveyor guarding where a full-length body will not, and the fitted magnet with CMSE switches confirms gate extend and retract at each cycle.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-30S the Right Cylinder?
Size against neighbours: a 50 mm bore pushes 981.7 N at 0.5 MPa, while an 80 mm bore reaches 2513.3 N, so the 63 mm bore is the middle choice when 981 N is marginal but 2513 N is oversized. If your fixture needs the full 90 mm reach always, the fixed-stroke ACE63X90 does the same job more simply; pick this -30S version only when the extend stroke must be trimmed on site. The stop screw shortens the extend stroke only - it is a mechanical end stop, not a mid-stroke lock, so on air loss the piston still drifts and a separate holding valve is needed for suspended loads. Mounting: FA flange, LB foot, plus I and Y rod knuckles; the fitted -S magnet works with CMSE / DMSE switches.
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 ACEJ63X90-30S FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa push is 2182.1 N. Theoretical maximum is 317.9 kgf at 1.0 MPa. The -30 code gives a 30 mm adjustment window, so the extend stroke can be trimmed anywhere from 90 mm down to 60 mm with the external stop screw. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the port is 1/8" (PT).
It is an ISO 21287 compact cylinder: hard-anodized aluminium body with a 16 mm hard-chrome-plated S45C rod, threaded aluminium covers, and a fixed TPU bumper at each end that only decelerates at the ends of travel - about 50% shorter mounting length than an ISO 15552 profile cylinder. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches mount directly in the body slots. FA flange and LB foot mounts, plus I/Y rod knuckles, bolt to the standard face; the female rod thread is M10x1.5.
