Airtac ACE Compact Cylinder ACE125X160S
The AirTAC Airtac ACE Compact Cylinder ACE125X160S is a genuine double acting ISO 21287 compact air cylinder with a Ø125mm bore and 160mm 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 ACE125X160S
This AirTAC ACE125X160S is a double acting compact cylinder that extends and retracts its rod with air pressure. It delivers a 6135.9 N push force and a 5890.5 N pull force at 0.5 MPa, making it a heavy-duty choice for large automation tasks. The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames where a full-length cylinder would not.
With the -S magnet already fitted, you can mount CMSE or DMSE reed or solid-state switches to confirm rod position. The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in continuous cycling. For a 2:1 safety margin on vertical lifts, plan to lift about 313 kg with this cylinder at 0.5 MPa, not the full 6135.9 N rating.

Where the Airtac ACE Compact Cylinder ACE125X160S Is Used
Heavy Press Toggle
Use this cylinder to actuate a toggle clamp on a 50-ton press brake, where the 6135.9 N push force at 0.5 MPa drives the linkage reliably. The short body fits within the press frame's limited clearance.
Pallet Stops
In a conveyor system for heavy pallets, this cylinder with 160 mm stroke lifts or lowers a stop pin. The 5890.5 N pull force retracts the pin quickly, and the magnet enables position sensing for automated control.
Die Casting Ejector
Mount this cylinder on a die casting machine to eject large aluminum parts. The 8590.3 N push at 0.7 MPa clears stuck castings, while the fixed TPU bumper absorbs the end-of-stroke impact without damage.
Is the Airtac ACE Compact Cylinder ACE125X160S the Right Cylinder?
Choose this 125 mm bore when you need forces above 5000 N at shop air. If your application requires less force, the 100 mm bore ACE100X160S provides 3927.0 N push at 0.5 MPa, while a larger 125 mm bore with a longer stroke can handle bigger parts. The 160 mm stroke suits medium-travel tasks; for longer reach, consider a non-standard stroke up to 300 mm standard maximum for this bore. Remember, this cylinder does not hold its position if air pressure is lost - use a rod lock or pilot check valve for load holding. The 1/4" port matches common industrial fittings, and the female M16x2.0 rod thread accepts standard attachments.
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 ACE125X160S FAQ
At 0.5 MPa, push force is 6135.9 N and pull force is 5890.5 N. At 0.7 MPa, push force is 8590.3 N and pull force 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).
The ACE125X160S has a short body that saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, so it fits in tight spaces. It has a fixed TPU bumper at both ends to absorb impact, not an adjustable cushion. The optional -S magnet is fitted here, allowing CMSE or DMSE switches for position sensing.
