Airtac ACE Compact Cylinder ACE50X5B
The AirTAC Airtac ACE Compact Cylinder ACE50X5B is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 5mm stroke, 1/8" 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 ACE50X5B
This AirTAC ACE50X5B is a double acting ISO 21287 compact cylinder with a 50 mm bore and a 5 mm stroke, delivering 981.7 N of push force at 0.5 MPa. The short body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a full-length cylinder will not. The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in high-cycle automation.
For a 5 mm stroke, the fixed TPU bumper at both ends absorbs the impact of rapid cycling, and the speed range of 30-500 mm/s suits pick-and-place tasks. Since this unit has no -S code, there is no magnet fitted, so CMSE or DMSE sensors cannot be mounted; order the optional -S magnet if you need position sensing. As a buyer insight, plan for about 60 kg of safe working load at 0.5 MPa (0.6 times the push force), which gives a 2:1 margin for real applications.

Where the Airtac ACE Compact Cylinder ACE50X5B Is Used
Fixture Clamping
Use the ACE50X5B to clamp small parts in a CNC fixture; the 5 mm stroke is enough to secure a workpiece, and the 981.7 N push at 0.5 MPa holds it firmly during machining.
Stop Gate
Mount this cylinder on a conveyor line to raise a stop gate for product separation. The short stroke and fixed TPU bumper handle frequent cycling without shock to the frame.
Ejector Pin
In an injection mold, the ACE50X5B can eject a small molded part with a 5 mm push. The 881.2 N pull force at 0.5 MPa retracts the pin reliably after each cycle.
Is the Airtac ACE Compact Cylinder ACE50X5B the Right Cylinder?
Choose the ACE50X5B when you need a very short stroke of 5 mm with a 50 mm bore. For lighter duty, the ACE32X25 offers 402.1 N push at 0.5 MPa, while the ACE63X25 provides 1558.6 N push at 0.5 MPa if you need more force. This model has a male rod thread (B code), which simplifies mounting with rod-end accessories. Since there is no magnet, it cannot be used with CMSE or DMSE switches unless you order the -S version; for load holding, use a separate rod lock or pilot check valve because the cylinder does not hold position when air is removed.
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 ACE50X5B FAQ
At 0.5 MPa, push force is 981.7 N and pull force is 881.2 N. At 0.7 MPa, push force is 1374.4 N and pull force is 1233.7 N. The theoretical maximum force is 200.2 kgf at 1.0 MPa. Operating pressure range is 0.15-1.0 MPa (22-145 psi), with proof pressure at 1.5 MPa (215 psi).
It is an ISO 21287 compact cylinder, meaning its body is about 50% shorter than an ISO 15552 profile cylinder, saving space in tight installations. This model has no magnet because it lacks the -S code, so CMSE or DMSE sensors cannot be mounted. To use sensors, you must order the version with the optional -S magnet. The fixed TPU bumper absorbs end-of-stroke impact, but it does not lock or hold the load.
