About the Airtac ACE Compact Cylinder ACE25X15SB
This AirTAC ACE25X15SB is a double acting ISO 21287 compact cylinder with a 25 mm bore and a 15 mm stroke, delivering a 245.4 N push force at 0.5 MPa. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight jigs and guards where a full-length cylinder will not. The male rod thread (B code) and the fitted optional -S magnet for CMSE or DMSE switches make it ready for automated sensing.
With a pull force of 206.2 N at 0.5 MPa, this unit handles light assembly tasks with ease. For a safe working load, plan for about 147 N of real work at 0.5 MPa, which lifts roughly 15 kg vertically with a 2:1 margin. The fixed TPU bumper at both ends absorbs end-of-stroke energy, and the hard-anodized aluminium body with an S45C hard-chrome rod ensures long service life in repetitive cycles.

Where the Airtac ACE Compact Cylinder ACE25X15SB Is Used
Fixture Clamping
Use the 245.4 N push force to clamp small parts in a CNC fixture, with the compact body fitting under a workholding vise.
Label Applicator
Drive a label applicator head in a packaging line, where the 15 mm stroke and 206.2 N pull retract the head cleanly after each cycle.
Sorting Gate
Operate a diverting gate in a conveyor system, using the fitted magnet to trigger a CMSE switch for position feedback at each end.
Is the Airtac ACE Compact Cylinder ACE25X15SB the Right Cylinder?
For a smaller option, the ACE20X15 offers a 157.1 N push at 0.5 MPa, while the ACE32X15 provides a stronger 402.1 N push for heavier loads. Since this model has a 15 mm stroke, it suits short-travel applications like clamping or indexing. The optional -S magnet is fitted here, so you can mount CMSE or DMSE reed or solid-state switches for position sensing. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all compatible with the ISO 21287 face.
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 ACE25X15SB FAQ
At 0.5 MPa, the push force is 245.4 N and the pull force is 206.2 N. At 0.7 MPa, push is 343.6 N and pull is 288.6 N. The theoretical maximum force is 50.1 kgf at 1.0 MPa.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits in tight spaces. The fixed TPU bumper absorbs end-of-stroke impact, and the optional -S magnet enables CMSE or DMSE switches for reliable sensing.
