Airtac ACE Compact Cylinder ACE100X125S
The AirTAC Airtac ACE Compact Cylinder ACE100X125S is a genuine double acting ISO 21287 compact air cylinder with a Ø100mm bore and 125mm stroke, 1/4" 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 ACE100X125S
This AirTAC ACE100X125S is a double acting compact cylinder that extends and retracts its rod with air pressure, delivering a robust 3927 N push force at 0.5 MPa. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, letting it fit into tight machine frames and guarding where a full-length unit will not.
With the optional -S magnet already fitted, this model works with CMSE or DMSE reed and solid-state switches for reliable position sensing. For a real-world load, plan for about 240 kg of safe vertical lift at 0.5 MPa, which is roughly 60% of the rated push, giving you a comfortable margin for jigs and fixtures.

Where the Airtac ACE Compact Cylinder ACE100X125S Is Used
Press Platen Lift
Use this cylinder to lift a 200 kg press platen in a stamping die setup, where the compact body fits between the frame rails and the 3927 N push handles the load with a 2:1 safety factor.
Conveyor Stop Gate
Mount this on a packaging line to raise a stop gate that diverts heavy cartons. The 125 mm stroke moves the gate fully clear, and the fitted magnet lets a CMSE switch confirm the gate is down.
Machine Guard Door
In a CNC machining cell, this cylinder actuates a sliding safety door. Its short body tucks behind the guard frame, and the 3769.9 N pull retracts the door smoothly against the fixed TPU bumper.
Is the Airtac ACE Compact Cylinder ACE100X125S the Right Cylinder?
Choose this 100 mm bore when you need a strong push in a compact envelope; it produces 3927 N at 0.5 MPa, while a smaller 63 mm bore gives 1558.6 N for lighter duties. If you need more power, the 125 mm bore steps up to 6135.9 N at the same pressure. This model has a 125 mm stroke, well within the 300 mm maximum standard stroke for this bore, so it is a standard off-the-shelf unit. Remember, this cylinder does not hold its position if air pressure is lost, so add a rod lock or pilot check valve for any load that must stay put.
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 ACE100X125S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3769.9 N. At 0.7 MPa, push rises to 5497.8 N and pull to 5277.9 N. The theoretical maximum force is 800.9 kgf at 1.0 MPa. The port is 1/4 inch and the rod thread is M12x1.75.
The ACE100X125S has a short body that saves about 50% of the mounting length compared to an ISO 15552 profile cylinder. This lets it fit into compact jigs and guards. It also has a fixed TPU bumper at both ends to absorb end-of-stroke impact, and the optional -S magnet enables CMSE or DMSE sensors for position feedback.
