About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-50S
The ACEJ63X50-50S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 50 mm stroke anywhere in a 0-50 mm window, so one unit can be dialled in on the machine without reordering. At 0.5 MPa the 63 mm bore delivers 1558.6 N on extend and 1458.1 N on retract, rising to 2182.1 N / 2041.3 N at 0.7 MPa. Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into tight clamping fixtures and gantry frames where a full-length cylinder will not fit.
This -S version carries the optional magnet, so CMSE or DMSE reed and solid-state switches can be clipped onto the body for end-of-stroke signalling. The hard-anodized aluminium body pairs with a 16 mm S45C hard-chrome-plated rod, a fixed TPU bumper at each end absorbs end-of-stroke energy, and the female M10x1.5 rod thread plus 1/8" ports drop into standard ISO 21287 fixtures. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), it cycles at 30-500 mm/s. For sizing, treat roughly 936 N (about 0.6 of the push force) as the practical working force, which corresponds to lifting about 95 kg vertically - or about 47 kg with a 2:1 margin.

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 ACEJ63X50-50S Is Used
Clamp fixture on a CNC machining line
The 1558.6 N extend force at 0.5 MPa holds steel housings in a milling fixture, while the 0-50 mm trim lets the setter match the clamp point to each part family.
Small-parts press station
A bearing or bushing press-in job needs about 936 N of usable force - well inside this bore's rating - and the short body fits the confined press head.
Gantry pick-and-place with position feedback
With the -S magnet fitted, CMSE or DMSE switches signal extend and retract on a transfer gantry lifting roughly 47 kg parts with a 2:1 vertical margin.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-50S the Right Cylinder?
Check the load both ways before committing. If your clamping or pressing job needs under 981.7 N push at 0.5 MPa, the 50 mm bore is the cheaper pick; if you need more than 1558.6 N, step up to the 80 mm bore at 2513.3 N. The 50 mm adjustment window suits stations where the final stroke is tuned during commissioning. Remember the stop screw only shortens the extend stroke and is not a mid-stroke lock - on air loss the piston drifts, so add a separate holding valve for suspended loads. Bolt on FA flange or LB foot mounts, order the -S magnet (fitted here) for CMSE / DMSE switch feedback, and confirm outline dimensions from the datasheet before cutting the bracket.
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 ACEJ63X50-50S 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 -50 code sets a 50 mm adjustment window: an external stop screw shortens the 50 mm extend stroke anywhere from 0 to 50 mm. It is a mechanical end stop only - it never holds a load on air loss. Speed range is 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).
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, 16 mm hard-chrome rod and fixed TPU bumpers at both ends. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted along the body slots. FA flange and LB foot mounts plus I and Y rod knuckles bolt to the standard face; the rod end is female M10x1.5 and ports are 1/8".
