About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X40-40SB
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ63X40-40SB pairs a 63 mm bore with a 40 mm stroke that an external stop screw can trim anywhere in the 0-40 mm window. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa, with a theoretical ceiling of 317.9 kgf at 1.0 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures a full-length body cannot reach.
The hard-anodized aluminium body carries a 16 mm S45C hard-chrome rod with a male thread (the B code), and this model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted for end-of-stroke signalling. As a planning figure, the 0.5 MPa push force supports roughly 936 N of real work (about 95 kg lifted vertically with a 2:1 margin), so match your part weight before committing. Fixed TPU bumpers absorb end-of-stroke energy 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 ACEJ63X40-40SB Is Used
Fixture clamping on CNC pallets
The 1558.6 N push at 0.5 MPa clamps machined housings in a jig, and the stop screw lets one cylinder serve several pallet sizes by trimming the extend stroke within 0-40 mm.
Palletizer push-off arm
A short-stroke kicker that nudges cartons off a conveyor lane; the compact body fits under the guard rail where an ISO 15552 profile cylinder would overhang the frame.
Press-fit verification station
With the -S magnet fitted, CMSE / DMSE switches confirm the rod reached the trimmed end position on each bearing press cycle, flagging short-loaded parts.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X40-40SB the Right Cylinder?
Size against neighbours: the 50 mm bore gives 981.7 N push at 0.5 MPa, while stepping up to the 80 mm bore raises it to 2513.3 N, so pick the 63 mm when your load sits between those bands. Remember the stop screw only shortens the extend stroke within the ordered 40 mm window and drifts on air loss, so it is not a mid-stroke lock. FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face, and the fitted -S magnet accepts CMSE / DMSE switches. Ports are 1/8" PT; the max standard stroke for this bore is 250 mm.
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 ACEJ63X40-40SB FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa, 2182.1 N push and 2041.3 N pull; theoretical maximum is 317.9 kgf at 1.0 MPa. The -40 code is a 40 mm adjustment window: an external stop screw shortens the 40 mm extend stroke on site, giving a usable range of 0-40 mm. It shortens only, never lengthens, and it is a mechanical end stop, not a load-holding lock.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder. FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the standard face. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be fitted for position signals. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with fixed TPU bumpers at both ends.
