About the Airtac SAI50 Standard Cylinder SAI50X165
The AirTAC SAI50X165 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 165mm stroke. It generates a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for medium-duty handling and positioning tasks. The extruded aluminum barrel design integrates standardized mounting dimensions for direct interchangeability with other ISO 15552 profile cylinders.
This specific configuration utilizes a standard carbon steel piston rod and PT tapered port threads. Because a magnetic piston is not specified, position sensing relies on external limit switches rather than embedded groove sensors.

Where the Airtac SAI50 Standard Cylinder SAI50X165 Is Used
Component Clamping
Provides reliable 982 N clamping force at 0.5 MPa for securing workpieces during machining or assembly operations.
Package Diverting
The 165mm stroke offers sufficient travel to actuate diverting arms or sorting gates on medium-sized packaging conveyor lines.
Material Ejection
Delivers consistent push force to eject molded parts or stamped blanks from press beds without requiring high-pressure systems.
Is the Airtac SAI50 Standard Cylinder SAI50X165 the Right Cylinder?
If your application requires slightly less force, stepping down to a 40mm bore yields 628 N of push force at 0.5 MPa. Conversely, upgrading to a 63mm bore provides 1559 N for heavier loads. The 165mm stroke falls within the 1200mm standard maximum, so no made-to-order surcharge applies.
For this mid-range stroke length, side load is minimal but rod-bearing wear can still occur if the load is offset. Ensure proper linear guidance for heavy payloads. Note that a standard SAI cylinder relies on live air pressure to hold position; if air is lost, the piston drifts. For fail-safe holding, specify the SAIL variant with an air-released lock or use an external rod lock.
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 SAI50X165 FAQ
