Airtac ACE Compact Cylinder ACE50X20
The AirTAC Airtac ACE Compact Cylinder ACE50X20 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 ACE50X20
This ACE50X20 is a double acting compact cylinder that uses air to both extend and retract the rod, with a fixed TPU bumper at each end to absorb impact. At 0.5 MPa it delivers 981.7 N of push force, which translates to a safe working load of about 589 N when you apply a 0.6 derating factor for real-world friction and side loads.
Its ISO 21287 short body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames where a full-length unit will not. The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear, and the 1/8" port suits standard shop air lines. Since this model has no -S code, it has no magnet, so CMSE or DMSE sensors cannot be mounted unless you order the optional magnet version.

Where the Airtac ACE Compact Cylinder ACE50X20 Is Used
Fixture Clamping
Use the ACE50X20 to clamp a workpiece in a CNC milling fixture. Its 981.7 N push force holds parts securely during machining, and the short body fits under the spindle without interfering with tool paths.
Carton Ejection
In a packaging line, this cylinder can eject a filled carton from a conveyor onto a chute. The 20 mm stroke provides a quick, controlled push, and the fixed TPU bumper prevents shock to the carton at the end of travel.
Press Ram
For a small bench press, the ACE50X20 acts as the ram to stamp or form sheet metal parts. Its 1374.4 N push at 0.7 MPa gives enough force for light forming, and the compact body keeps the press footprint small.
Is the Airtac ACE Compact Cylinder ACE50X20 the Right Cylinder?
For a lighter duty application, the ACE40X20 offers 628.3 N push at 0.5 MPa, while this ACE50X20 nearly doubles that with 981.7 N. If you need more force, step up to the ACE63X20, which provides 1558.6 N push at the same pressure. This 20 mm stroke is short, so it suits clamping or pressing operations where travel is minimal but force is essential.
Since the stroke is well under the 250 mm maximum standard for this bore, it is a stock item. Choose the -S option if you need position sensing with CMSE or DMSE switches; without it, no sensor can be fitted. Mounting options like FA/FB flanges or LB foot brackets bolt directly to the ISO 21287 face, and the female M10x1.5 rod thread accepts standard rod clevis hardware.
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 ACE50X20 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 is 1374.4 N and pull is 1233.7 N. The theoretical maximum force is 200.2 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa (22-145 psi), with a proof pressure of 1.5 MPa (215 psi).
The ACE50X20 has a short body that saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, so it fits in tight spaces like guard enclosures or gantries. It uses a fixed TPU bumper at both ends to absorb impact, and the hard-anodized aluminium body resists corrosion. The optional -S magnet enables CMSE or DMSE sensors for position feedback.
