About the Airtac SAI50 Standard Cylinder SAI50BX170S
The AirTAC SAI50X170-S is a double-acting ISO 15552 profile cylinder built to deliver 982 N of push force at 0.5 MPa. Because this 170 mm stroke is a non-standard length, it is manufactured as a made-to-order unit to suit specific machinery envelopes. The extruded aluminum barrel design omits tie rods, providing a clean exterior that integrates seamlessly into modern automated equipment.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in wet or washdown environments. It is equipped with a magnetic piston (-S) for use with CMSE or DMSE reed sensors, and features PT tapered port threads for reliable pneumatic sealing.

Where the Airtac SAI50 Standard Cylinder SAI50BX170S Is Used
Washdown Actuation
The SUS304 rod resists corrosion in food processing or packaging lines where frequent washdowns occur.
Package Diverting
Provides 982 N of push force to reliably divert heavy cartons on a high-speed sorting conveyor.
Clamp Positioning
The 170 mm stroke accurately moves and holds workpieces in custom machining or welding fixtures.
Is the Airtac SAI50 Standard Cylinder SAI50BX170S the Right Cylinder?
Selecting this 50 mm bore provides a balanced output of 982 N push and 825 N pull at 0.5 MPa. If your application requires less force, the 40 mm bore offers 628 N push, while heavy-duty tasks can step up to the 63 mm bore providing 1559 N. Because this is a 170 mm non-standard stroke, ensure your machinery has the exact extended length clearance required.
For any stroke at or beyond 300 mm, side loads can cause rod-bearing bending and premature wear; utilize an external guide rail or a guided cylinder to manage off-axis forces. Furthermore, this standard SAI cylinder relies on live air pressure to maintain position. If your system loses air, the load will drift; use the SAIL variant with an air-released lock or a BSAI clamp-lock for fail-safe holding. As a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard ISO 15552 unit matching the 50 mm bore, 170 mm stroke, PT G1/4 port, and FA flange or LB foot mounting.
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 SAI50BX170S FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. At the maximum 1.0 MPa pressure, it can reach up to 200 kgf.
Yes. The SAI50X170-S is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke. You can use existing mounting accessories like TC trunnions or FA flanges.
