About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-50
The ACEJ63X55-50 is a double acting ISO 21287 compact cylinder with a 63 mm bore and a 55 mm stroke that an external stop screw trims on site. The -50 code sets a 50 mm adjustment window, so the usable extend stroke spans 5-55 mm. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; a practical rule of thumb keeps about 935 N (roughly 95 kg) of that as real working force. Air ports are 1/8", the rod end carries a female M10x1.5 thread, and speed runs 30-500 mm/s.
The hard-anodized aluminium body with an S45C hard-chrome plated rod is built for long jig duty, and the short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight gantries and guarding. Fixed TPU bumpers at both ends absorb end-of-stroke shock. For position feedback, order the optional -S magnet code; without it no CMSE or DMSE switch can be fitted. FA flange, LB foot and I/Y rod knuckles bolt straight to the ISO 21287 face.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
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 ACEJ63X55-50 Is Used
Press-fit clamping of aluminium housings
With 1558.6 N push at 0.5 MPa, the 63 mm bore seats light aluminium housings into assembly jigs, and the 50 mm window lets one cylinder serve several housing heights from 5 to 55 mm.
Packaging line pusher gates
The short ISO 21287 body fits beside narrow conveyor frames where a full-length profile cylinder will not, trimming the extend stroke to match lane widths on the fly.
CNC fixture part ejection
Mounted via FA flange on machining fixtures, the cylinder kicks finished parts clear of locators; about 935 N of usable force at 0.5 MPa clears chips and parts without marking surfaces.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-50 the Right Cylinder?
Size against load: the next bore down, ACEJ50, delivers 981.7 N push at 0.5 MPa, while the step up to ACEJ80 gives 2513.3 N. If your clamping or pressing load sits near 900-950 N, this 63 mm bore keeps a comfortable margin at 0.5 MPa. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock: on air loss the piston still drifts, so do not rely on it to hold a suspended load.
Match the fixture before ordering: FA flange or LB foot mount to the standard ISO 21287 face, and the female M10x1.5 rod thread suits standard rod eyes and knuckles. If sensors are planned, specify the -S magnet version at order time - it cannot be retrofitted.
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 ACEJ63X55-50 FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa push rises to 2182.1 N and pull to 2041.3 N, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -50 code is a 50 mm adjustment window: an external stop screw shortens the 55 mm extend stroke by up to 50 mm, giving a usable range of 5-55 mm. It shortens the stroke only and never extends it past the ordered 55 mm.
This is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with fixed TPU bumpers at both ends absorbing end-of-stroke shock. The magnet is the optional -S code: only when ordered can CMSE or DMSE switches detect position - this model, without S, carries no magnet. FA flange, LB foot and I/Y rod knuckles mount directly to the ISO 21287 face, and the female M10x1.5 rod thread accepts standard tooling.
