Airtac ACE Compact Cylinder ACE50X25
The AirTAC Airtac ACE Compact Cylinder ACE50X25 is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 25mm stroke, 1/8" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACE Compact Cylinder ACE50X25
This AirTAC ACE50X25 is a double acting compact cylinder with a 50 mm bore and 25 mm stroke, delivering 981.7 N of push force at 0.5 MPa. Its ISO 21287 short body takes up about 50% less mounting length than an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a longer cylinder would not.
For real-world sizing, plan for about 60 kg of usable vertical lift at 0.5 MPa (0.6 times the 981.7 N push, divided by 9.81), which gives a 2:1 safety margin over the theoretical 200.2 kgf maximum. The body is hard-anodized aluminium with a hard-chrome S45C rod, and the fixed TPU bumper at both ends absorbs end-of-stroke impact without needing adjustment.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACE Compact Cylinder ACE50X25 Is Used
Fixture Clamping
Use the ACE50X25 to clamp small parts in a CNC fixture; its 981.7 N push holds aluminum blanks securely during light milling operations.
Carton Tabbing
In a packaging line, this cylinder can push a tab or flap into place on a corrugated box, with the 25 mm stroke matching the flap depth and the compact body fitting between conveyor rails.
Guard Door Interlock
Mount the ACE50X25 on a machine guard to push a locking pin into a bracket; the short stroke and 881.2 N pull retract the pin quickly when air is applied.
Is the Airtac ACE Compact Cylinder ACE50X25 the Right Cylinder?
Choose the ACE50X25 when you need a compact 50 mm bore cylinder with a short 25 mm stroke for light assembly or clamping tasks. If you need more force, step up to the 63 mm bore which pushes 1558.6 N at 0.5 MPa; if space is tighter, the 40 mm bore pushes 628.3 N at 0.5 MPa. This model has no magnet (no -S code), so it cannot accept CMSE or DMSE sensors; order the optional -S version if you need position sensing. The 1/8" port and M10x1.5 female rod thread suit standard fittings and attachments.
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 ACE Compact Cylinder ACE50X25 FAQ
At 0.5 MPa, the push force is 981.7 N and the pull force is 881.2 N. At 0.7 MPa, push is 1374.4 N and pull is 1233.7 N. The theoretical maximum force is 200.2 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa (22-145 psi).
It is an ISO 21287 compact cylinder, meaning its body is about 50% shorter than an ISO 15552 profile cylinder, saving space in tight installations. This model has no magnet (no -S code), so it cannot be used with CMSE or DMSE sensors; you must order the optional -S version to add a magnet for sensor detection.
