About the Airtac ACE Compact Cylinder ACE125X30S
This AirTAC ACE125X30S is a double acting compact cylinder built to ISO 21287, with a hard-anodized aluminium body and a hard-chrome plated S45C steel rod. It delivers a 6135.9 N push force at 0.5 MPa, so it suits heavy clamping and pressing tasks in tight spaces.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, letting it fit inside machine guards and compact jigs. The optional -S magnet is fitted here, so CMSE or DMSE switches can mount directly to sense rod position. For a safe working load, plan around 3682 N (about 375 kg) at 0.5 MPa rather than the full rating, giving a 2:1 margin for real applications.

Theoretical Output Force (Ø125mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 6136 N | 5890 N |
| 0.7 MPa | 8590 N | 8247 N |
| Max (@1.0 MPa) | 1251 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 ACE125X30S Is Used
Heavy Clamping Fixture
Use in a CNC machining fixture to clamp large steel workpieces with 6135.9 N force, holding parts firmly during milling operations.
Press Ram for Assembly
Drive a pressing ram in an automotive assembly line to insert bearings or bushings, relying on the 30 mm stroke for precise, short travel.
Compact Die-Casting Ejector
Mount inside a die-casting machine's ejector box, where the short body fits limited space and the high force pushes out castings.
Is the Airtac ACE Compact Cylinder ACE125X30S the Right Cylinder?
Choose the ACE125X30S when you need a 125 mm bore with a 30 mm stroke and high force in a short envelope. For lighter duty, the ACE100X30S offers 3927.0 N push at 0.5 MPa, while the ACE125X50S provides a longer 50 mm stroke if travel is critical. This model has a female M16x2.0 rod thread and a 1/4" port, and the fitted magnet enables position sensing with CMSE or DMSE switches. Remember that a plain ACE does not hold its load when air is lost; use a rod lock or pilot check valve for vertical or suspended loads.
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 ACE125X30S FAQ
At 0.5 MPa, push is 6135.9 N and pull is 5890.5 N. At 0.7 MPa, push is 8590.3 N and pull is 8246.7 N. The theoretical maximum force is 1251.4 kgf at 1.0 MPa. Operating pressure range is 0.15-1.0 MPa (22-145 psi), with proof pressure 1.5 MPa (215 psi).
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits in tight spaces like machine guards and compact jigs. It has a fixed TPU bumper at both ends to absorb end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE sensors to detect rod position. Mounting options include FA/FB flange, LB foot, and CA/CB clevis.
