About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X70-10B
The ACEJ63X70-10B is a double acting ISO 21287 compact cylinder with a 63 mm bore and a 70 mm stroke that an external stop screw trims on site. The -10 code gives a 10 mm adjustment window, so the usable extend stroke can be set anywhere from 60 to 70 mm without changing hardware. 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, which is why it slots into tight machine frames and gantries.
For sizing, plan on roughly 935 N of real work at 0.5 MPa (about 0.6 of the push rating) rather than the full figure; divided across gravity, that is a vertical lift of about 79 kg with a 2:1 margin. The hard-anodized aluminium body carries a roller-burnished bore, the 16 mm S45C rod is hard-chrome plated, and a fixed TPU bumper at each end absorbs end-of-stroke shock. Air ports are 1/8" PT, and the B code delivers a male rod thread.

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 ACEJ63X70-10B Is Used
CNC fixture clamping
The 1558.6 N push at 0.5 MPa clamps steel or aluminium workpieces in machining fixtures, and the 60-70 mm trim lets one cylinder serve several part heights.
Press-fit and staking stations
With about 935 N of usable working force, the bore handles light press-fit, staking and marking jobs on small assembly lines where floor space is tight.
Packaging line diverters
Running at 30-500 mm/s, the short 70 mm body pushes cartons into diverters or checkweighers on food and beverage conveyors where a full-length profile cylinder will not fit.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X70-10B the Right Cylinder?
At 1558.6 N push at 0.5 MPa, this 63 mm bore sits between the 50 mm bore (981.7 N) and the 80 mm bore (2513.3 N); step down when the load is under 900 N, step up when it approaches 1500 N. The stop screw shortens the extend stroke only - it never lengthens it past 70 mm, and it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost. FA flange or LB foot mounts bolt to the ISO 21287 face, and I or Y rod knuckles suit the male thread. If you need position feedback, order the -S variant: without it there is no magnet and no CMSE / DMSE switch can be read.
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 ACEJ63X70-10B 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; the theoretical maximum is 317.9 kgf at 1.0 MPa. The -10 code sets a 10 mm adjustment window: an external stop screw shortens the 70 mm extend stroke to any value from 60 to 70 mm. It is a mechanical end stop only - on air loss the piston still drifts, so it does not hold a load. 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, with a hard-anodized aluminium body and a hard-chrome plated 16 mm rod. Air ports are 1/8" PT and the B code gives a male rod thread. FA flange and LB foot mounts bolt straight to the standard face. Position sensing requires the optional -S magnet code - this model has no magnet, so CMSE / DMSE switches cannot be mounted unless you order -S.
