Airtac ACE Compact Cylinder ACE25X15
The AirTAC Airtac ACE Compact Cylinder ACE25X15 is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 15mm 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 ACE25X15
This AirTAC ACE25X15 is a double acting compact cylinder built to ISO 21287, with a 25 mm bore and a 15 mm stroke. Its short, hard-anodized aluminium 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 won't go.
At 0.5 MPa it pushes with 245.4 N and pulls with 206.2 N, which translates to a practical vertical lift of about 15 kg when you apply a 2:1 safety margin. The fixed TPU bumper at each end softens impact, and the M5x0.8 port keeps the air path compact for small-bore automation.

Where the Airtac ACE Compact Cylinder ACE25X15 Is Used
Fixture Clamping
Use the ACE25X15 to clamp small parts in a CNC fixture; its 245.4 N push at 0.5 MPa holds light components securely during drilling or milling.
Tight Guard Doors
Mount this cylinder inside a machine guard to operate a small safety door or window. The short ISO 21287 body fits in the limited depth behind the guarding panel.
High-Speed Sorting
In a packaging line, the ACE25X15 can push small cartons onto a conveyor at speeds up to 500 mm/s, with the fixed TPU bumper absorbing the end-of-stroke shock.
Is the Airtac ACE Compact Cylinder ACE25X15 the Right Cylinder?
For a lighter load, the ACE20X15 offers 157.1 N push at 0.5 MPa, while stepping up to the ACE32X15 gives you 402.1 N push for heavier work. Since this model has no magnet (the -S code is optional), you cannot fit CMSE or DMSE sensors unless you order the magnet version. Choose FA, FB, LB, CA, CB, CR, SDB, or FTC mounting brackets to match your fixture.
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 ACE25X15 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 operating pressure range is 0.15-1.0 MPa (22-145 psi).
Only if you order the -S option, which adds a magnet to the piston. Without the -S code, there is no magnet, so CMSE or DMSE reed or solid-state switches cannot be mounted. This model has a fixed TPU bumper at both ends, not an adjustable cushion, and operates from -20 to 70 C.
