About the Airtac SAI50 Standard Cylinder SAI50X170S
The AirTAC SAI50X170-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 170 mm stroke provides the exact mid-range extension needed for automated clamping and lifting tasks. The extruded aluminum barrel design eliminates tie-rods, ensuring a clean exterior that resists debris accumulation.
This specific configuration includes a magnetic piston (-S) for seamless integration with CMSE or DMSE reed switches along the dual sensor grooves. It utilizes a standard carbon steel piston rod and features PT tapered port threads, making it a highly reliable choice for general industrial pneumatics.

Where the Airtac SAI50 Standard Cylinder SAI50X170S Is Used
Automated Clamping
Provides 982 N of secure clamping force at 0.5 MPa for holding aluminum or steel workpieces during CNC machining and milling processes.
Package Diverting
Utilizes the 170 mm stroke to extend diverting arms on packaging lines, rapidly routing boxes to secondary processing lanes.
Material Lifting
Lifts lightweight mechanical subcomponents between manufacturing stations, relying on the magnetic piston for precise end-of-stroke confirmation.
Is the Airtac SAI50 Standard Cylinder SAI50X170S the Right Cylinder?
Selecting this 50 mm bore is ideal when a 40 mm bore (628 N at 0.5 MPa) lacks the necessary thrust, but a 63 mm bore (1559 N) would be excessive. The 170 mm stroke offers a balanced footprint for compact machinery. Because the stroke is under 300 mm, side-load stress on the rod bearing is naturally minimized.
As a standard double-acting cylinder, it requires continuous air pressure to maintain its position; if pressure is lost, the load will drift. For applications requiring dead-stop holding without live air, consider the SAIL variant with an air-released lock. To replace an existing unit, match the 50 mm bore, 170 mm stroke, G1/4 PT port, and mounting accessories like FA flanges or LB foot brackets.
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 SAI50X170S 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. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X170-S is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders by matching the 50 mm bore, 170 mm stroke, and G1/4 port size.
