About the Airtac ACE Compact Cylinder ACE125X160B
This AirTAC ACE125X160B is a double acting ISO 21287 compact cylinder with a 125 mm bore and 160 mm stroke. It delivers 6135.9 N of push force and 5890.5 N of pull force at 0.5 MPa, making it a heavyweight in a short-body format. The hard-anodized aluminium body and S45C hard-chrome plated rod are built for demanding cycles.
The ISO 21287 design cuts mounting length by about 50% compared to an ISO 15552 profile cylinder, so it fits into tight machine frames where a full-length unit will not. For a 2:1 safety margin, plan to lift about 313 kg vertically with this bore at 0.5 MPa, which helps you match it to real part weights. The fixed TPU bumper at both ends absorbs end-of-stroke impact, but it does not lock or hold a load in position.

Where the Airtac ACE Compact Cylinder ACE125X160B Is Used
Heavy Press Ram
Use this 125 mm bore cylinder as a press ram for stamping or forming metal brackets, delivering 6135.9 N of force at 0.5 MPa to drive dies through sheet steel.
Die Casting Ejector
In die casting machines, this compact cylinder ejects solidified parts from molds. Its 160 mm stroke clears deep cavities while the short body fits between tie bars.
Bulk Bag Clamp
Mount this cylinder on a conveyor line to clamp and hold bulk bags during filling. The 5890.5 N pull force at 0.5 MPa secures heavy loads without slipping.
Is the Airtac ACE Compact Cylinder ACE125X160B the Right Cylinder?
This 125 mm bore unit suits heavy pushing and pressing applications where space is limited. If your load is lighter, the 100 mm bore version pushes 3927.0 N at 0.5 MPa, while this 125 mm bore gives you 6135.9 N for roughly 56% more force. The 160 mm stroke is within the 300 mm maximum standard stroke for this bore, so no custom build is required.
The B code specifies a male rod thread, which simplifies mounting when you need to attach a tool directly. Since this model has no S code, it has no magnet, so CMSE or DMSE sensors cannot be fitted. Order the -S version if you need position sensing. The 1/4" port matches standard industrial fittings for high-flow applications.
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 ACE125X160B FAQ
At 0.5 MPa, the push force is 6135.9 N and the 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).
The ACE125X160B follows ISO 21287 compact dimensions, which saves about 50% of the mounting length compared to an ISO 15552 profile cylinder. The body is hard-anodized aluminium with a fixed TPU bumper at both ends. This model has no magnet, so order the -S version if you need to mount CMSE or DMSE sensors.
