About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-10
The ACEJ63X55-10 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. A 63 mm bore delivers 1558.6 N push and 1458.1 N pull at 0.5 MPa, rising to 2182.1 N at 0.7 MPa, with a theoretical peak of 317.9 kgf at 1.0 MPa. The -10 code means an external stop screw trims the 55 mm extend stroke by up to 10 mm on site, so the usable range is 45-55 mm without changing the cylinder.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in tight welding jigs and press fixtures. As a rule of thumb, plan for roughly 935 N of real work at 0.5 MPa, which lifts about 79 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries a 16 mm S45C hard-chrome rod, fixed TPU bumpers absorb end-of-stroke shock, and FA flange or LB foot mounts bolt straight to the standard face. Note this unit has no magnet fitted: order the optional -S code if you need CMSE / DMSE switch sensing.

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 ACEJ63X55-10 Is Used
Welding fixture clamping
The 1558.6 N push at 0.5 MPa seats steel brackets into weld jigs, and the 45-55 mm adjustable range lets one cylinder serve slightly different fixture depths.
Small press and staking
With about 2182.1 N at 0.7 MPa, this bore handles light staking and crimping on electronics assemblies where a full-length ISO 15552 cylinder will not fit.
Packaging line stops
The 16 mm hard-chrome rod and 30-500 mm/s speed suit diverting and stopping cartons on bottling conveyors, with LB foot mounting on tight machine frames.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-10 the Right Cylinder?
At 63 mm bore this sits in the mid-heavy class: a 50 mm bore gives 981.7 N push at 0.5 MPa, while an 80 mm bore steps up to 2513.3 N. If your jig needs more than 1558.6 N at 0.5 MPa, go 80; if under 1000 N, the 50 saves space. The stop screw only shortens the extend stroke and is not a mid-stroke lock, so on air loss the piston still drifts. FA flange and LB foot mounts plus I/Y rod knuckles fit standard ISO 21287 fixtures, and the optional -S magnet enables CMSE / DMSE switches for end-position sensing.
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 ACEJ63X55-10 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; theoretical maximum is 317.9 kgf at 1.0 MPa. The -10 code is a 10 mm adjustment window: an external stop screw shortens the 55 mm extend stroke to any length from 45 to 55 mm. It is a mechanical end stop only, not a mid-stroke lock, so the piston still drifts if air is lost. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with fixed TPU bumpers 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 fits guarded gantries and dense fixture plates. Air ports are 1/8" PT, the rod end has a female M10x1.5 thread, and FA flange or LB foot mounts bolt to the standard face. Position sensing requires the optional -S magnet: this model has no magnet fitted, so order ACEJ63X55-10S if you want CMSE or DMSE switches to detect end positions.
