Airtac ACE Compact Cylinder ACE50X50B
The AirTAC Airtac ACE Compact Cylinder ACE50X50B is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 50mm 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 ACE50X50B
This AirTAC ACE50X50B is a double acting compact cylinder that extends and retracts its rod with air pressure on both strokes. It delivers 981.7 N of push force at 0.5 MPa, so it suits medium-duty clamping and pressing tasks in tight automation cells.
The ISO 21287 short body is about 50% shorter than an ISO 15552 profile cylinder, freeing valuable space in gantries and guarded machines. The male rod thread (B code) simplifies direct coupling to tooling, and the fixed TPU bumper absorbs end-of-stroke impact, but it does not lock or hold a load. For a safe working load, plan around 589 N (about 60 kg) at 0.5 MPa to leave a 2:1 margin for real-world friction and acceleration.

Where the Airtac ACE Compact Cylinder ACE50X50B Is Used
Fixture Clamping
Use in a CNC fixture to clamp a 5 kg aluminum bracket during drilling. The 981.7 N push at 0.5 MPa holds the part firmly, and the compact body fits under the spindle guard.
Carton Tabbing
In a packaging line, this cylinder pushes a folding tab into a corrugated carton. The 50 mm stroke matches the tab depth, and the fixed TPU bumper prevents jarring the carton at high cycle rates.
Stop Gate
Mount on a conveyor to raise a stop gate that diverts boxes to a reject lane. The 881.2 N pull at 0.5 MPa retracts the gate quickly, and the male rod thread connects to a simple linkage.
Is the Airtac ACE Compact Cylinder ACE50X50B the Right Cylinder?
For lighter indexing or small part ejection, the ACE40X50B offers 628.3 N push at 0.5 MPa, while this ACE50X50B steps up to 981.7 N for heavier fixtures. If you need more force, the ACE63X50B provides 1558.6 N push at 0.5 MPa, but check the port size changes to 1/8" for bores 32-63 mm.
This model has no magnet, so it cannot trigger CMSE or DMSE sensors. Order the ACE50X50B-S variant if you need position sensing. Mounting options like FA/FB flange, LB foot, or CA/CB clevis bolt directly to the ISO 21287 face, and the 50 mm stroke suits short-travel applications up to the 250 mm maximum standard stroke.
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 ACE50X50B FAQ
At 0.5 MPa, push is 981.7 N and pull is 881.2 N. At 0.7 MPa, push rises to 1374.4 N and pull to 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 a proof pressure of 1.5 MPa (215 psi).
The ACE50X50B follows ISO 21287, so its body is about 50% shorter than an ISO 15552 profile cylinder, saving space in tight machines. It uses a fixed TPU bumper at both ends to absorb impact, but this bumper is not adjustable and does not lock the rod. For holding a load when air is off, add a rod lock or pilot check valve.
