Airtac ACE Compact Cylinder ACE32X125
The AirTAC Airtac ACE Compact Cylinder ACE32X125 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 ACE32X125
This AirTAC ACE32X125 is a double acting compact cylinder that uses air to both extend and retract the rod, delivering a 402.1 N 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 fixed TPU bumper at each end absorbs impact, and the S45C hard-chrome rod resists wear in continuous cycling.
At 0.5 MPa, the pull force is 345.6 N, and at 0.7 MPa the push rises to 563 N. For a real application, plan for about 241 N of safe working load, which equals roughly 25 kg of vertical lift with a 2:1 safety margin. The 1/8" port suits standard fittings, and the M8x1.25 female rod thread accepts common attachments. This model has no magnet fitted, so it cannot trigger a sensor unless you order the optional -S code.

Where the Airtac ACE Compact Cylinder ACE32X125 Is Used
Fixture Clamping
Use the ACE32X125 to clamp small parts in a CNC fixture. Its 402.1 N push force at 0.5 MPa holds components securely, and the compact body fits between vise jaws without protruding.
Conveyor Stop Gate
Mount this cylinder on a packaging line to raise a stop gate. The 125 mm stroke clears the conveyor path, and the fixed TPU bumper prevents noisy end-of-stroke impact at speeds up to 500 mm/s.
Machine Guard Lock
In a robotic cell, the ACE32X125 can actuate a safety guard latch. Its short body saves space behind the guard panel, and the double acting design ensures positive retraction when air is applied.
Is the Airtac ACE Compact Cylinder ACE32X125 the Right Cylinder?
Choose the ACE32X125 when you need a compact 32 mm bore cylinder with a 125 mm stroke for moderate force duties. For lighter tasks, the ACE25X125 offers 245.4 N push at 0.5 MPa, while stepping up to the ACE40X125 gives 628.3 N push for heavier loads. Since this is a double acting cylinder, it will not hold its position if air pressure is lost or the valve is centered; use a rod lock or pilot check valve for load holding. The 1/8" port and M8x1.25 rod thread match standard accessories, and you can add FA/FB flange, LB foot, or CA/CB clevis mounts. Remember, the magnet is optional - order the -S code if you need CMSE or DMSE switches.
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 ACE32X125 FAQ
At 0.5 MPa, the push force is 402.1 N and the pull force is 345.6 N. At 0.7 MPa, the push is 563 N and the pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. These values are based on the 32 mm bore and 12 mm rod.
The ACE32X125 has a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder, so it fits in tight spaces like machine guards or gantries. It uses a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet enables CMSE or DMSE sensors for position detection.
