About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X40-40B
The ACEJ63X40-40B is a double acting AirTAC compact cylinder built to ISO 21287, with a 63 mm bore and a 40 mm stroke that an external stop screw trims on site anywhere in the 0-40 mm window set by the -40 code. 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 comfortably in the mid-heavy thrust class. The male (B code) rod thread on the 16 mm rod bolts straight to standard fixtures, and FA flange or LB foot mounts land on the same ISO 21287 face.
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a press jig or gantry leaves no room for a full-length body. For sizing, treat roughly 0.6 of the push force as usable work: about 935 N, which lifts roughly 95 kg vertically - halve that for a 2:1 margin and it comfortably raises a 47 kg die or pallet fixture. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the hard-anodized aluminium body with an S45C hard-chrome rod resists wear in 30-500 mm/s duty. Note this unit carries no magnet; order the -S code if you later need CMSE / DMSE switch position feedback.

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 ACEJ63X40-40B Is Used
Press-jig clamping
The 1558.6 N push at 0.5 MPa clamps aluminium die-cast housings in a machining jig, with the 0-40 mm adjustment absorbing fixture height variation between part numbers.
Pallet lift-and-lower station
Lifts about 95 kg vertically at 0.5 MPa (roughly 47 kg with a 2:1 margin), raising palletized automotive brackets a short 40 mm lift into a locating nest.
Gantry ejector on SMT lines
The short ISO 21287 body fits inside a tight PCB gantry frame, ejecting rejected boards from the conveyor lane with the stroke trimmed to match lane depth.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X40-40B the Right Cylinder?
At 63 mm bore this model delivers 1558.6 N push at 0.5 MPa. Step down to the 50 mm bore (981.7 N) for lighter clamping, or up to the 80 mm bore (2513.3 N) when a heavier stamping or forming load demands more thrust. Ports are 1/8" on both, so plumbing stays simple. 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 will still drift if air is lost and a separate holding method is needed for suspended loads. Specify the -S magnet code at order time if CMSE / DMSE switches will be fitted later; the standard unit has no magnet.
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 ACEJ63X40-40B 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; theoretical maximum is 317.9 kgf at 1.0 MPa. The -40 code sets a 40 mm adjustment window: an external stop screw shortens the 40 mm extend stroke on site anywhere from 0 to 40 mm. It never lengthens the stroke past the ordered 40 mm, and the stop is an end stop only - it does not hold a load against air loss. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at both ends.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guards and gantries. FA flange and LB foot mounts plus I and Y rod knuckles bolt to the standard face, and the male rod thread (B code) suits couplers. Position sensing requires the optional -S magnet code - this unit has no magnet, so CMSE / DMSE switches only work if -S is ordered. Ports are 1/8"; the max standard stroke for this bore is 250 mm if you need a longer version.
