Airtac ACE Compact Cylinder ACE50X20H
The AirTAC Airtac ACE Compact Cylinder ACE50X20H is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 20mm 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 ACE50X20H
This AirTAC ACE50X20H is a double acting compact cylinder built to ISO 21287, with a 50 mm bore and a 20 mm stroke. It delivers 981.7 N of push force at 0.5 MPa, making it a solid choice for medium-duty automation tasks.
The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, which helps it fit into tight machine frames. The fixed TPU bumper absorbs end-of-stroke impact, and the 1/8" port keeps installation simple. For a safe working load, plan for about 589 N at 0.5 MPa, which translates to lifting roughly 60 kg vertically with a 2:1 safety margin.

Where the Airtac ACE Compact Cylinder ACE50X20H Is Used
Assembly Press
Use the 981.7 N push force to drive a small arbor press for inserting bearings or bushings into housings on an assembly line.
Carton Closer
Mount this cylinder to fold and close the flaps of cardboard boxes before sealing, with the 20 mm stroke providing quick, repeatable motion.
Sorting Gate
Actuate a diverter gate on a conveyor to route products to different lanes, relying on the compact body to fit within the conveyor frame.
Is the Airtac ACE Compact Cylinder ACE50X20H the Right Cylinder?
When sizing, consider the ACE40 with 628.3 N push at 0.5 MPa for lighter applications, or step up to the ACE63 with 1558.6 N push for more demanding loads. This 50 mm bore version offers a balanced force-to-size ratio for many industrial uses.
Since this model has no -S code, it lacks the optional magnet for sensor mounting. If you need position sensing with CMSE or DMSE switches, order the -S variant. The female M10x1.5 rod thread and standard mounting options like FA/FB flange or LB foot make it adaptable to existing fixtures.
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 ACE50X20H FAQ
At 0.5 MPa, the push force is 981.7 N and the pull force is 881.2 N. At 0.7 MPa, push increases to 1374.4 N and pull to 1233.7 N. The theoretical maximum force is 200.2 kgf at 1.0 MPa.
Yes, it is an ISO 21287 compact cylinder with a body about 50% shorter than an ISO 15552 profile cylinder. However, this version has no magnet, so it cannot be used with CMSE or DMSE sensors. You would need the -S option for that.
