About the Airtac SAI50 Standard Cylinder SAI50BX200S
The AirTAC SAI50X200-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 200 mm stroke provides the precise extension needed for mid-range material handling and packaging machinery. The extruded aluminum barrel design eliminates tie-rods, ensuring a clean exterior that drops directly into standard ISO 15552 mounting footprints.
This specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance in humid or washdown environments. Equipped with a built-in magnet (-S), it seamlessly integrates with CMSE and DMSE sensor switches seated in the dual side grooves. The cylinder uses PT tapered port threading and includes adjustable air cushions at both ends to smooth out piston deceleration.

Where the Airtac SAI50 Standard Cylinder SAI50BX200S Is Used
Packaging Machinery
Drives sealing and folding arms with 982 N of thrust, utilizing the SUS304 rod to withstand occasional washdowns.
Product Diverting
Extends 200 mm to push cartons off a main conveyor belt, using integrated DMSE sensors to confirm stroke completion.
Clamp Fixtures
Secures lightweight wooden or composite workpieces during secondary machining operations without marking the surface.
Is the Airtac SAI50 Standard Cylinder SAI50BX200S the Right Cylinder?
Select this 50 mm bore when an application requires stepping up from the 40 mm class (628 N at 0.5 MPa) without the bulk of a 63 mm body. For operations needing position holding without continuous air pressure, a standard SAI will drift when exhausted; consider the SAIL variant for an integrated air-released lock. Because this unit features a 200 mm stroke, it remains well within standard unsupported rod limits, though external guides should still be used to manage any lateral loads.
To match this cylinder exactly, specify the 50 mm bore, 200 mm stroke, G1/4 port size, and the -S magnet requirement. It is dimensionally interchangeable with other ISO 15552 profile cylinders. Pair it with FA or FB flange accessories, or TC trunnion mounts, depending on your pivot or fixed centerline requirements.
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 SAI50BX200S FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 1374 N.
Yes. The SAI50X200-S is a true ISO 15552 profile cylinder, making its mounting dimensions fully interchangeable with other standard ISO 15552 cylinders. Ensure you match the G1/4 port and 200 mm stroke.
