Airtac ACE Compact Cylinder ACE50X55
The AirTAC Airtac ACE Compact Cylinder ACE50X55 is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 55mm 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 ACE50X55
This AirTAC ACE50X55 is a double acting ISO 21287 compact cylinder with a 50 mm bore and 55 mm stroke, delivering 981.7 N of push force at 0.5 MPa. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight machine frames and guarding where space is at a premium.
For real-world sizing, plan on about 60 kg of usable vertical lift at 0.5 MPa (981.7 N divided by 9.81 and halved for a 2:1 safety margin). The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear, while the fixed TPU bumper at each end absorbs end-of-stroke impact without needing adjustment.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACE Compact Cylinder ACE50X55 Is Used
Fixture Clamping
Clamp small aluminum parts in a CNC fixture with 981.7 N push force, holding them securely during drilling or milling operations without taking up excessive machine envelope.
Stop Gate Actuation
Actuate a stop gate on a packaging conveyor to divert boxes weighing up to 60 kg, using the 55 mm stroke to lift the gate clear of the product flow.
Press Ram for Gaskets
Drive a small press ram to seat rubber gaskets into housings, relying on the 881.2 N retract force to pull the ram back cleanly after each cycle.
Is the Airtac ACE Compact Cylinder ACE50X55 the Right Cylinder?
For lighter loads, the ACE40X55 offers 628.3 N push at 0.5 MPa, while stepping up to the ACE63X55 gives you 1558.6 N push at the same pressure. This ACE50X55 sits in the middle, balancing force and footprint for medium-duty automation tasks.
Since this model has no magnet (no -S code), it cannot accept CMSE or DMSE sensors. If you need position sensing, order the -S version. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all compatible with 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 ACE50X55 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. Operating pressure range is 0.15-1.0 MPa (22-145 psi).
No, this model is without the optional -S magnet, so CMSE or DMSE switches cannot be mounted. The magnet is only available when you order the -S code. The cylinder uses a fixed TPU bumper at both ends, not an adjustable cushion, and operates at speeds from 30 to 500 mm/s.
