Airtac ACE Compact Cylinder ACE25X90B
The AirTAC Airtac ACE Compact Cylinder ACE25X90B is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 90mm 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 ACE25X90B
This AirTAC ACE25X90B is a double acting ISO 21287 compact cylinder with a 25 mm bore and a 90 mm stroke, delivering 245.4 N of push force at 0.5 MPa. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames where a full-length unit will not. The S45C carbon-steel rod is hard-chrome plated and has a male thread (B code) for direct coupling to tooling.
For real-world sizing, plan on about 15 kg of safe working load at 0.5 MPa, which is roughly 60% of the rated push. The fixed TPU bumper at both ends absorbs end-of-stroke impact, but it does not lock or hold a load; if the air supply is lost, the piston drifts. Since this model has no -S code, there is no magnet fitted, so CMSE or DMSE sensors cannot be mounted without ordering the optional -S variant.

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 ACE25X90B Is Used
Tight-Fit Jig Clamping
Mount this 90 mm stroke cylinder inside a CNC fixture to clamp small aluminum parts. Its short body saves about half the length of a profile cylinder, leaving room for other tooling.
Carton Tabbing
Use the 245.4 N push to press folded carton tabs into place on a packaging line. The male rod thread connects directly to a custom pusher plate, and the fixed bumper handles rapid cycling.
Guard Door Interlock
Actuate a safety guard interlock on a small assembly machine. The 90 mm stroke moves a latch out of the way, and the compact body fits within the guard frame without protruding.
Is the Airtac ACE Compact Cylinder ACE25X90B the Right Cylinder?
For a lighter duty, the ACE20X90B offers 157.1 N push at 0.5 MPa, while stepping up to the ACE32X90B gives 402.1 N push for heavier loads. Choose this 25 mm bore when you need a balance of force and compactness in a space-constrained jig. The M5x0.8 port is standard for this bore, and the male rod thread simplifies mounting to a clevis or rod end. Remember, without the -S magnet, position sensing is not possible, so order ACE25X90SB if you need to detect the piston position.
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 ACE25X90B 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).
It follows ISO 21287, a compact standard that cuts the mounting length by about 50% compared to an ISO 15552 profile cylinder. The body is hard-anodized aluminium, and the fixed TPU bumper at each end absorbs impact. This model has no magnet, so to use CMSE or DMSE sensors, you must order the -S version.
