Airtac ACE Compact Cylinder ACE25X150B
The AirTAC Airtac ACE Compact Cylinder ACE25X150B is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 150mm 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 ACE25X150B
This AirTAC ACE25X150B 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. Its 25 mm bore delivers a 245.4 N push force at 0.5 MPa, so at that pressure you can plan for roughly 15 kg of real vertical lifting work when you apply a 2:1 safety margin.
The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, which lets it fit into tight jigs and guards where a full-length unit will not. The male rod thread (B code) is ready for direct coupling, and the M5x0.8 port keeps the footprint small, while the hard-anodized aluminium body and hard-chrome plated S45C rod resist wear in continuous cycling.

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 ACE25X150B Is Used
Fixture Clamping
Use the 245.4 N push to clamp small aluminium parts in a CNC fixture, where the short body clears the spindle and the male rod thread simplifies the clamp arm.
Label Applicator
Drive a label applicator head in a packaging line, using the 150 mm stroke to reach across a conveyor and the fixed TPU bumper to prevent product damage at high cycle rates.
Guard Door Stop
Position a safety guard door stop on a light assembly machine, where the compact ISO 21287 body fits within a slim frame and the 206.2 N pull retracts the stop reliably.
Is the Airtac ACE Compact Cylinder ACE25X150B the Right Cylinder?
For a lighter push, the ACE20X150 offers 157.1 N at 0.5 MPa, while stepping up to the ACE32X150 gives you 402.1 N at the same pressure. Since this model has no optional -S magnet, it cannot accept CMSE or DMSE sensors; order the -S code if you need position sensing. The 150 mm stroke is the maximum standard for this bore, so if you need longer travel, confirm the non-standard stroke availability from the datasheet.
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 ACE25X150B 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) with a proof pressure of 1.5 MPa (215 psi).
The ACE25X150B body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into compact machine frames, guarding, and gantries where a full-length cylinder would not. It uses a fixed TPU bumper at both ends, not an adjustable cushion, and operates at speeds from 30-500 mm/s. The M5x0.8 port is standard for this 25 mm bore.
