Airtac ACE Compact Cylinder ACE25X30SB
The AirTAC Airtac ACE Compact Cylinder ACE25X30SB is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 30mm stroke, M5×0.8 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 ACE25X30SB
This AirTAC ACE25X30SB is a double acting ISO 21287 compact cylinder with a 25 mm bore and 30 mm stroke, delivering 245.4 N push and 206.2 N pull at 0.5 MPa. Its short body cuts mounting length by about half versus an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a full-length unit will not.
The hard-anodized aluminium body and S45C hard-chrome rod resist wear in continuous cycling. With the optional -S magnet fitted, CMSE or DMSE switches can be mounted for position sensing. For a real workload at 0.5 MPa, plan for roughly 15 kg of vertical lift (245.4 N divided by 9.81, then halved for a 2:1 safety margin), not the full theoretical rating.

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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 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 ACE25X30SB Is Used
Fixture Clamping
Use in a CNC fixture to clamp small aluminum parts during drilling or milling. The 245.4 N push at 0.5 MPa holds workpieces securely, and the compact body fits under the spindle without interfering with tool paths.
Part Ejection
Mount on a conveyor line to push finished components off a belt into a chute. The 30 mm stroke provides a quick, repeatable nudge, and the optional -S magnet lets a CMSE switch confirm each ejection cycle.
Guard Door Interlock
Actuate a small safety door or access panel on a packaging machine. The double acting action extends and retracts the rod positively, and the short body saves space on the machine frame, allowing easy integration with existing guards.
Is the Airtac ACE Compact Cylinder ACE25X30SB the Right Cylinder?
Choose this 25 mm bore when you need moderate force in a short envelope. For lighter tasks, the 20 mm bore gives 157.1 N push at 0.5 MPa, while stepping up to 32 mm provides 402.1 N push for heavier clamping or pressing. The 30 mm stroke suits short travel applications like part ejection or valve actuation.
The male rod thread (B code) simplifies mounting with rod-end accessories. The M5x0.8 port is standard for this bore. Since the magnet is fitted, you can add CMSE or DMSE switches for position feedback, but remember this cylinder does not hold its load if air pressure is lost - use a rod lock or pilot check valve for safety-critical holding.
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 ACE25X30SB FAQ
At 0.5 MPa, push is 245.4 N and pull is 206.2 N. At 0.7 MPa, push rises to 343.6 N and pull to 288.6 N. The theoretical maximum force at 1.0 MPa is 50.1 kgf. Port is M5x0.8, and the rod is 10 mm with a male thread.
The magnet is an optional -S feature, and this model is ordered with it, so CMSE or DMSE reed or solid-state switches can be mounted for position detection. Without the -S code, no magnet is present. The cylinder has a fixed TPU bumper at both ends, not an adjustable cushion, and operates at speeds from 30 to 500 mm/s.
