About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-40
The ACEJ63X55-40 is a double acting AirTAC compact cylinder built to ISO 21287, with a 63 mm bore and a 55 mm stroke that an external stop screw trims on site. The -40 code means a 40 mm adjustment window, so the usable extend stroke spans 15-55 mm; the screw shortens the stroke only, never past the ordered 55 mm. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, and at 0.7 MPa those rise to 2182.1 N and 2041.3 N. A practical planning figure: treat roughly 935 N as the usable working force, which corresponds to lifting about 79 kg vertically with a 2:1 margin.
The hard-anodized aluminium body with an S45C hard-chrome plated 16 mm rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding. A fixed TPU bumper at each end absorbs end-of-stroke impact, and the stop screw is a mechanical end stop only - on air loss the piston still drifts, so it never holds a load. Ports are 1/8" with a PT thread, the rod end is female M10x1.5, and the optional -S magnet enables CMSE / DMSE switches; this model without the S code carries no magnet.

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 ACEJ63X55-40 Is Used
Ejector on a press-fit fixture
Pushing finished bearing housings out of a locating nest on an automotive machining cell, where the 15-55 mm trimmed stroke matches shallow part pockets and 1558.6 N clears press-fit friction.
Case stop on a carton line
Raising a stop blade to index corrugated cases at a packing station; the short ISO 21287 body fits under the conveyor frame and the 40 mm window lets the line tune the index pitch.
Pallet clamp on a stretch wrapper
Clamping pallet loads against a back plate before wrapping, using about 935 N of practical force at 0.5 MPa and the LB foot mounting inside a compact machine guard.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-40 the Right Cylinder?
Size against neighbours: the 50 mm bore delivers 981.7 N push at 0.5 MPa, while stepping up to the 80 mm bore gives 2513.3 N - pick the 63 mm when your load sits between roughly 600 and 950 N of real work. Remember the stop screw sets the end of the extend stroke; it is not a mid-stroke lock, so use a separate valve or check arrangement where position must be held under air loss. FA flange or LB foot mountings bolt to the ISO 21287 face, and if you need position feedback order the -S variant so CMSE / DMSE switches can sense the piston.
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 ACEJ63X55-40 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, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -40 code is a 40 mm adjustment window: an external stop screw shortens the 55 mm extend stroke anywhere down to 15 mm. It runs double acting on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a 1/8" PT port and female M10x1.5 rod thread.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends that absorb end-of-stroke energy. FA flange and LB foot mountings fit the standard face. Position sensing requires the optional -S magnet, which allows CMSE / DMSE switches; this model without the S code has no magnet, so no switch can be mounted.
