About the Airtac SAI50 Standard Cylinder SAI50X65S
The AirTAC SAI50X65-S is a double-acting ISO 15552 profile cylinder with a 50mm bore and 65mm stroke. It generates 982N of push force at 0.5 MPa and 1374N at 0.7 MPa, making it well-suited for medium-duty positioning tasks. The integrated -S magnet allows seamless mounting of CMSE or DMSE reed switches along the extruded aluminum barrel grooves.
Built strictly to ISO 15552 dimensional standards, this tie-rod-less profile cylinder serves as a direct replacement for other ISO 15552 interface actuators. The standard carbon steel piston rod provides durable service in general industrial environments, while the PT tapered port threads ensure a robust, leak-free pneumatic connection.

Where the Airtac SAI50 Standard Cylinder SAI50X65S Is Used
Short-Stroke Clamping
Ideal for holding workpieces firmly in machining fixtures using its 982N push force at 0.5 MPa over a compact 65mm travel.
Package Diverting
Provides rapid actuation for sorting gates on packaging lines, utilizing the magnetic piston for end-of-stroke position sensing.
Material Ejection
Delivers reliable push-off force to eject molded parts or stamped components from light-duty production machinery.
Is the Airtac SAI50 Standard Cylinder SAI50X65S the Right Cylinder?
Choose this 50mm bore when a 40mm bore (628N at 0.5 MPa) lacks the necessary thrust, but a 63mm bore (1559N at 0.5 MPa) would be physical overkill. The 65mm stroke is optimal for short-travel clamping and lifting. For applications requiring the load to stay suspended if air pressure drops, pair this cylinder with an external pilot-operated check valve or specify the SAIL variant with an integrated air-released lock. Being a genuine ISO 15552 profile cylinder, it shares exact mounting dimensions with industry-standard foot (LB), flange (FA), and trunnion (TC) accessories.
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.
