Airtac ACE Compact Cylinder ACE25X15BH
The AirTAC Airtac ACE Compact Cylinder ACE25X15BH 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 ACE25X15BH
This ACE25X15BH is a double acting compact cylinder that uses air to both extend and retract its 10 mm rod, with a fixed TPU bumper at each end to soften the stop. With a 25 mm bore it delivers 245.4 N of push force at 0.5 MPa, which is enough to handle light clamping or positioning tasks in a tight space.
The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into compact jigs and guards where a full-length unit will not. The male rod thread (B code) simplifies mounting, and the hard-anodized aluminium body with an S45C hard-chrome rod resists wear in repetitive cycles. Since this unit has no -S code, it has no magnet, so CMSE or DMSE sensors cannot be fitted unless you order the optional -S version. For a real-world load, plan on about 147 N (15 kg) of safe working force at 0.5 MPa, not the full 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 ACE25X15BH Is Used
Fixture Clamping
Use in a CNC fixture to clamp small aluminum brackets with 245.4 N push force at 0.5 MPa, fitting into a compact jig where a standard cylinder is too long.
Label Applicator
Drive a label tamp head on a packaging line with a 15 mm stroke, providing quick, repeatable extension to press labels onto small cartons.
Guard Door Stop
Mount on a machine guard to push a light interlock pin into place, using the short ISO 21287 body to fit within a slim profile frame.
Is the Airtac ACE Compact Cylinder ACE25X15BH the Right Cylinder?
When sizing, compare this 25 mm bore with the 20 mm bore (157.1 N push at 0.5 MPa) for lighter duty, or step up to the 32 mm bore (402.1 N push at 0.5 MPa) if you need more force. The 15 mm stroke suits short travel applications, and the M5x0.8 port is common for small-bore circuits. This model has a male rod thread, so check your attachment fitting. Since there is no magnet, it will not work with proximity sensors; order the -S variant if you need position sensing. The fixed TPU bumper handles end-of-stroke impact, but it does not hold a load if air pressure is lost, so add a rod lock or pilot check valve for vertical or safety-critical applications.
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 ACE25X15BH 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 at 1.0 MPa is 50.1 kgf. The operating pressure range is 0.15-1.0 MPa (22-145 psi) with a proof pressure of 1.5 MPa (215 psi).
The ACE25X15BH follows ISO 21287, so its body is about 50% shorter than an ISO 15552 profile cylinder, saving space in tight mounts. It has a fixed TPU bumper at both ends to absorb impact, not an adjustable air cushion. This model has no magnet, so it cannot use CMSE or DMSE switches; you must order the -S code version to get the optional magnet for sensor mounting.
