About the Airtac ACE Compact Cylinder ACE32X25SH
This AirTAC ACE32X25SH is a double acting ISO 21287 compact cylinder with a 32 mm bore and 25 mm stroke, delivering 402.1 N of push force at 0.5 MPa. Its short body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, making it ideal for tight automation cells where space is at a premium.
With the optional -S magnet fitted, this model works with CMSE or DMSE reed and solid-state switches for reliable position sensing. For real-world applications, plan on a usable vertical lift of about 25 kg at 0.5 MPa, which accounts for a 2:1 safety margin on the theoretical force. The fixed TPU bumper absorbs end-of-stroke energy, and the hard-anodized aluminium body with a hard-chrome plated S45C steel rod ensures long service life in demanding environments.

Where the Airtac ACE Compact Cylinder ACE32X25SH Is Used
Fixture Clamping on CNC Machines
Use the 402.1 N push force to clamp small workpieces on a CNC milling fixture. The compact body fits between T-slot rails where a standard cylinder would not clear the spindle head.
Carton Tabbing in Packaging Lines
Drive a tabbing mechanism that folds and seals carton flaps on a high-speed packaging line. The 25 mm stroke provides just enough travel for the flap, while the -S magnet enables precise cycle counting with a DMSE sensor.
Parts Ejection from Assembly Jigs
Eject finished parts from an assembly jig after the final screw-driving step. The 345.6 N retract force pulls the ejector pin back quickly, and the fixed TPU bumper prevents shock to delicate components.
Is the Airtac ACE Compact Cylinder ACE32X25SH the Right Cylinder?
When sizing this 32 mm bore cylinder, compare it against the 25 mm bore which offers 245.4 N push at 0.5 MPa, or the 40 mm bore which provides 628.3 N push at the same pressure. The 25 mm stroke is well within the 200 mm maximum standard stroke for this bore size, so no special ordering is required. For mounting, the ISO 21287 face pattern accepts FA/FB flanges, LB foot brackets, CA/CB clevises, and SDB pivot mounts. Since this model includes the -S magnet, you can directly attach CMSE or DMSE sensors for position feedback. Remember that this cylinder does not hold its position when air pressure is lost - use a rod lock or pilot check valve for load holding.
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 ACE32X25SH FAQ
At 0.5 MPa, the push force is 402.1 N and the pull force is 345.6 N. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum force at 1.0 MPa is 82 kgf. These figures are based on the 32 mm bore and 12 mm rod diameter.
The ACE32X25SH body is about 50% shorter than an equivalent ISO 15552 profile cylinder, which lets you fit it into tight machine guards and gantries. It uses a fixed TPU bumper at both ends to absorb impact, and the hard-anodized aluminium body resists wear. The -S magnet is fitted on this model, so you can mount CMSE or DMSE switches for position detection.
