Airtac ACE Compact Cylinder ACE50X125SBFTC
The AirTAC Airtac ACE Compact Cylinder ACE50X125SBFTC is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 125mm 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 ACE50X125SBFTC
This AirTAC ACE50X125SBFTC is a double acting ISO 21287 compact cylinder that extends and retracts its 16 mm rod with air pressure on both strokes. Its 50 mm bore delivers 981.7 N push and 881.2 N pull at 0.5 MPa, with a theoretical maximum of 200.2 kgf at 1.0 MPa.
The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, saving space in tight fixtures. The optional -S magnet is fitted here, so CMSE or DMSE reed and solid-state switches can mount directly. For a 2:1 safety margin, plan to lift about 50 kg vertically at 0.5 MPa, not the full rated force.

Where the Airtac ACE Compact Cylinder ACE50X125SBFTC Is Used
Fixture Clamping
Clamp a 40 kg workpiece in a CNC milling fixture with the 981.7 N push force at 0.5 MPa, fitting the short body into a tight guard enclosure.
Carton Ejection
Eject filled cartons from a packaging line conveyor at 125 mm stroke, using the 881.2 N pull force to retract the rod reliably.
Sorting Gate
Divert parcels on a warehouse sorting conveyor with a 50 mm bore cylinder, where the compact body saves space between rollers.
Is the Airtac ACE Compact Cylinder ACE50X125SBFTC the Right Cylinder?
For a lighter duty, the ACE40X125 delivers 628.3 N push at 0.5 MPa, while stepping up to the ACE63X125 gives 1558.6 N push. This ACE50X125SBFTC with its 125 mm stroke suits medium-force applications where a compact envelope is key. The male rod thread (B) simplifies attachment, and the FTC mounting bracket is included for direct installation. Since the magnet is fitted, you can add CMSE or DMSE switches for position sensing. Remember, this cylinder does not hold its load if air pressure is lost; use a rod lock or pilot check valve for that.
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 ACE50X125SBFTC FAQ
At 0.5 MPa, push is 981.7 N and pull 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.
The magnet is an optional -S feature, and this model includes it. With the magnet fitted, you can mount CMSE or DMSE reed or solid-state switches. Without the -S code, there is no magnet.
