Airtac ACE Compact Cylinder ACE50X80
The AirTAC Airtac ACE Compact Cylinder ACE50X80 is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 80mm 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 ACE50X80
This AirTAC ACE50X80 is a double acting compact cylinder built to ISO 21287, with a hard-anodized aluminium body and a hard-chrome plated S45C steel rod. At 0.5 MPa it delivers 981.7 N of push force and 881.2 N of pull, so it suits medium-duty automation tasks.
The short ISO 21287 body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, letting it fit into tight machine frames and guarding. The fixed TPU bumper at each end absorbs impact, and the 1/8" port keeps installation simple. For a safe working load, plan for about 60 kg of real work at 0.5 MPa, which is roughly 0.6 times the push rating, so you keep a solid margin.

Where the Airtac ACE Compact Cylinder ACE50X80 Is Used
Fixture Clamping
Use the ACE50X80 to clamp workpieces in a CNC milling fixture. The 981.7 N push at 0.5 MPa holds parts securely, while the short body keeps the fixture compact and leaves room for tooling.
Package Stoppers
Mount this cylinder on a conveyor line to stop and release cartons. The 80 mm stroke provides enough travel to block or pass products, and the fixed TPU bumper handles repeated cycles at speeds up to 500 mm/s.
Press Ram
In a small bench press, this cylinder can drive a ram for light stamping or forming operations. Its 1374.4 N push at 0.7 MPa offers extra force when needed, and the compact body fits under a workbench guard.
Is the Airtac ACE Compact Cylinder ACE50X80 the Right Cylinder?
For lighter duty, the ACE40X80 offers 628.3 N push at 0.5 MPa, while the ACE63X80 steps up to 1558.6 N push. Choose this 50 mm bore when you need a balance of force and compact size. The stroke of 80 mm is well within the 250 mm maximum standard stroke for this bore. Since this model has no -S code, there is no magnet fitted, so CMSE or DMSE sensors cannot be mounted; order the -S option if you need position sensing. Mounting options like FA/FB flanges, LB foot brackets, and CA/CB clevises 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 ACE50X80 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. These are for double acting operation, where air extends and retracts the rod.
The ACE50X80 follows ISO 21287, so its body is about 50% shorter than an ISO 15552 profile cylinder, saving space in tight installations. It has a fixed TPU bumper at both ends to absorb impact. This model has no magnet, so you cannot mount CMSE or DMSE sensors; you would need to order the -S version for a built-in magnet.
