About the Airtac SAI50 Standard Cylinder SAI50X65
The AirTAC SAI50X65 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 65 mm stroke provides compact actuation for mid-range automation tasks. The extruded aluminum barrel design eliminates tie-rods, offering a clean exterior that simplifies mounting and maintenance.
This unit features a standard carbon steel piston rod and PT tapered port threads. Because it lacks a built-in magnet, position sensing requires external switches. For high-temperature environments up to 70 C, the standard TPU seals handle typical demands, while Viton (H) or NBR (N) options are available for specialized conditions.

Where the Airtac SAI50 Standard Cylinder SAI50X65 Is Used
Short-Stroke Clamping
Provides reliable 982 N clamping force for securing medium-sized workpieces during machining or welding operations.
Package Diverting
Actuates diverting arms or routing gates on packaging lines where a compact 65 mm stroke rapidly redirects product flow.
Material Ejection
Ejects molded or stamped parts from press beds, utilizing the 50 mm bore's quick extension to maintain cycle speeds.
Is the Airtac SAI50 Standard Cylinder SAI50X65 the Right Cylinder?
Choose this 50 mm bore when an application requires more power than a 40 mm bore (which provides 628 N at 0.5 MPa) but lacks the physical space for a 63 mm cylinder. The 65 mm stroke is optimal for short clamping or ejecting movements. To achieve direct interchangeability with other ISO 15552 cylinders, match the 50 mm bore, 65 mm stroke, G1/4 port, and appropriate mounting accessory like an FA flange or LB foot.
Because the standard SAI50X65 operates without a magnet, it cannot trigger reed or solid-state sensors directly. If automated position feedback is required, select the SAI50X65-S variant instead. Furthermore, this standard double-acting cylinder relies on continuous air pressure to maintain its position. If a load must be held securely during an air loss event, integrate an external pilot-operated check valve or specify the SAIL locking variant.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI50 Standard Cylinder SAI50X65 FAQ
At a standard operating pressure of 0.5 MPa, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. If pressure increases to 0.7 MPa, the push force rises to 1374 N.
Yes. The SAI50X65 is dimensionally interchangeable per ISO 15552. You can replace competing ISO 15552 cylinders by matching the 50 mm bore, 65 mm stroke, G1/4 port, and mounting interface without altering the machine frame.
