About the Airtac ACE Compact Cylinder ACE50X90
This AirTAC ACE50X90 is a double acting compact cylinder built to ISO 21287, with a 50 mm bore and a 90 mm stroke. It delivers 981.7 N of push force and 881.2 N of pull force at 0.5 MPa, making it a solid choice for mid-range automation tasks. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight machine frames where a longer cylinder would not.
At 0.5 MPa, a practical working load is about 60 kg (roughly 0.6 times the push force), which gives you a safe margin for real applications. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, while the fixed TPU bumper at each end absorbs impact. This model has no magnet, so it cannot accept sensors; order the -S option if you need CMSE or DMSE switches.

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 ACE50X90 Is Used
Fixture Clamping
Use in a CNC milling fixture to clamp a 50 mm thick aluminum plate with 981.7 N force at 0.5 MPa, holding it securely during a drilling cycle.
Carton Pusher
On a packaging line, this cylinder pushes a filled carton (up to 60 kg) from a conveyor onto a shrink-wrap station, using the 90 mm stroke for a smooth transfer.
Press Ram
In a small assembly press, the ACE50X90 drives a punch to insert a bearing into a housing, relying on the 1374.4 N push at 0.7 MPa for a firm press fit.
Is the Airtac ACE Compact Cylinder ACE50X90 the Right Cylinder?
For a lighter duty, the ACE40X90 offers 628.3 N push at 0.5 MPa, while the ACE63X90 provides 1558.6 N push for heavier loads. This ACE50X90 sits in the middle, suitable for clamping, pressing, or pushing parts up to about 60 kg at 0.5 MPa. Since it is double acting, air both extends and retracts the rod, but it will not hold a load if air pressure is lost; use a rod lock or pilot check valve for that. Mounting options include FA/FB flanges, 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 ACE50X90 FAQ
At 0.5 MPa, push is 981.7 N and pull 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 is 0.15-1.0 MPa (22-145 psi), with a proof pressure of 1.5 MPa (215 psi).
No, this ACE50X90 has no magnet, so no CMSE or DMSE sensor can be mounted. The magnet is an optional -S code addition. The cylinder uses a fixed TPU bumper at both ends to absorb impact, not an adjustable cushion. It operates at speeds from 30 to 500 mm/s and in temperatures from -20 to 70 C.
