Airtac ACE Compact Cylinder ACE32X125B
The AirTAC Airtac ACE Compact Cylinder ACE32X125B is a genuine double acting ISO 21287 compact air cylinder with a Ø32mm bore and 125mm stroke, 1/8" 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 ACE32X125B
This AirTAC ACE32X125B is a double acting ISO 21287 compact cylinder with a 32 mm bore and a 125 mm stroke, delivering 402.1 N of push force at 0.5 MPa. Its short body takes up about half the mounting length of an ISO 15552 profile cylinder, making it a strong fit for tight automation cells where space is at a premium.
The male rod thread (B code) simplifies direct coupling to tooling, and the hard-anodized aluminium body resists wear in high-cycle duties. At 0.5 MPa, plan for roughly 24.6 kg of usable vertical lift (about 60% of the rated force), so it can handle moderate part transfer or clamping tasks. The fixed TPU bumper softens end-of-stroke impact, but it does not hold a load if air pressure is lost, so use a rod lock for vertical holding.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 ACE32X125B Is Used
Fixture Clamping
Use in a CNC fixture to clamp small aluminium parts during drilling, with the 402.1 N push holding parts firmly at 0.5 MPa.
Parcel Stop Gate
Mount on a packaging conveyor to stop or divert lightweight boxes, relying on the 125 mm stroke to clear the belt path quickly.
Guard Door Actuator
Open or close a small safety guard on a press brake, where the compact body fits within the machine frame and the 345.6 N pull retracts the door.
Is the Airtac ACE Compact Cylinder ACE32X125B the Right Cylinder?
For lighter work, the ACE25X125 offers 245.4 N push at 0.5 MPa, while the ACE40X125 steps up to 628.3 N push, giving you a clear force ladder for sizing. Since this model has no -S magnet, it cannot accept CMSE or DMSE sensors; order the -S variant if you need position sensing. The 1/8" port suits standard flow rates for this bore, and the male rod thread is ideal for direct attachment of a clevis or custom bracket.
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 ACE32X125B FAQ
At 0.5 MPa, push is 402.1 N and pull is 345.6 N. At 0.7 MPa, push rises to 563.0 N and pull to 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. Operating pressure range is 0.15-1.0 MPa (22-145 psi), with a proof pressure of 1.5 MPa (215 psi).
No, this ACE32X125B does not include a magnet, so no CMSE or DMSE switch can be mounted. The magnet is an optional -S code addition; order ACE32X125BS if you need position sensing. The fixed TPU bumper at both ends decelerates the piston but does not lock the rod in place.
