About the Airtac ACE Compact Cylinder ACE50X15B
This AirTAC ACE50X15B is a double acting compact cylinder built to ISO 21287, with a 50 mm bore and a 15 mm stroke. It delivers 981.7 N of push force and 881.2 N of pull force at 0.5 MPa, making it a solid choice for mid-range automation tasks.
Its short body takes up about 50% less mounting length than an ISO 15552 profile cylinder, so it fits into tight machine frames. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, while the fixed TPU bumper at each end absorbs impact. For a real-world guide, plan for roughly 60 kg of safe working load at 0.5 MPa, which is about 60% of the rated push force.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 ACE50X15B Is Used
Jig Clamping
Use in a CNC fixture to clamp small parts with 981.7 N force at 0.5 MPa, fitting into tight spaces around the spindle.
Package Stop
Mount on a conveyor line to stop or divert lightweight boxes, with the short stroke of 15 mm for quick indexing.
Test Rig Actuator
In a lab test bench, cycle a lever or switch repeatedly at speeds up to 500 mm/s, relying on the fixed TPU bumper for quiet operation.
Is the Airtac ACE Compact Cylinder ACE50X15B the Right Cylinder?
When sizing, consider the ACE40X15B for lighter duty with 628.3 N push at 0.5 MPa, or the ACE63X15B for more power with 1558.6 N push. This ACE50X15B has a male rod thread (B code) and a 1/8" port, and it comes without a magnet, so no sensors can be mounted unless you order the optional -S magnet version. Mounting options like FA/FB flange, LB foot, or CA/CB clevis bolt directly to the ISO 21287 face.
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 ACE50X15B FAQ
At 0.5 MPa, push force is 981.7 N and pull force is 881.2 N. At 0.7 MPa, push is 1374.4 N and pull is 1233.7 N. The theoretical maximum force is 200.2 kgf at 1.0 MPa.
No, this ACE50X15B has no magnet, so CMSE or DMSE switches cannot be mounted. You would need to order the -S version to get the optional magnet for sensor detection.
