Airtac ACE Compact Cylinder ACE125X15B
The AirTAC Airtac ACE Compact Cylinder ACE125X15B is a genuine double acting ISO 21287 compact air cylinder with a Ø125mm bore and 15mm 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 ACE125X15B
This AirTAC ACE125X15B is a double acting compact cylinder that extends and retracts its 25 mm rod with air pressure on both strokes. It delivers 6135.9 N of push force at 0.5 MPa, so it suits heavy clamping and pressing work in large-scale automation.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which lets it fit into tight machine frames where a full-length cylinder will not. The male rod thread (B code) allows direct coupling to linkages without an adapter. For a real part weight, plan for about 375 kg of safe vertical lift at 0.5 MPa, using a 2:1 margin on the theoretical 6135.9 N push.

Where the Airtac ACE Compact Cylinder ACE125X15B Is Used
Heavy Clamping Fixture
Use the 6135.9 N push force to clamp large metal workpieces securely during CNC milling or drilling operations, holding them rigid against vibration.
Press Operation
In a stamping or forming press, this cylinder can drive a die or punch with enough force to shape sheet metal parts up to 15 mm stroke, ideal for short-stroke embossing.
Material Handling Stop
Mount it as a positive stop on a heavy-duty conveyor line to halt pallets or crates weighing up to 375 kg, using the short stroke to engage and disengage quickly.
Is the Airtac ACE Compact Cylinder ACE125X15B the Right Cylinder?
For a lighter duty, the ACE100X15B offers 3927.0 N push at 0.5 MPa, while the ACE125X15B gives you 6135.9 N for heavier loads. This model has no magnet fitted, so it cannot work with CMSE or DMSE sensors; order the -S code if you need position sensing. The 1/4" port and PT thread are standard for this 125 mm bore size.
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 ACE125X15B FAQ
At 0.5 MPa, push force is 6135.9 N and pull force 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).
It follows ISO 21287, so its body is about 50% shorter than an ISO 15552 profile cylinder of the same bore. This makes it easier to fit into tight spaces. It has a fixed TPU bumper at both ends to absorb impact, and the hard-anodized aluminium body resists wear. The optional -S magnet is needed for CMSE or DMSE sensors.
