About the Airtac SAI50 Standard Cylinder SAI50BX200H
The AirTAC SAI50X200 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 extended travel needed for mid-range material handling and automated clamping tasks.
This specific configuration incorporates a SUS304 stainless steel piston rod and high-temperature Viton (FKM) seals, expanding the operating envelope to safely handle hotter industrial environments. The extruded aluminum profile barrel features dual sensor grooves, allowing for straightforward position tracking when paired with magnetic switches.

Where the Airtac SAI50 Standard Cylinder SAI50BX200H Is Used
Hot End Ejection
Utilizes the Viton seals and SUS304 rod to reliably push molded components out of heated fixtures without seal degradation.
Diverting Arm
Provides the 982 N force and 200 mm reach needed to deflect heavy packages on a continuous material transport line.
Heavy Duty Clamping
Secures metal workpieces for machining operations, taking advantage of the robust ISO 15552 mounting interface.
Is the Airtac SAI50 Standard Cylinder SAI50BX200H the Right Cylinder?
Select this 50 mm bore when an application demands more power than the 40 mm version (628 N at 0.5 MPa) but lacks the physical space for a 63 mm unit. Because this model lacks a magnet, it cannot host reed or solid-state sensors directly; if position feedback is required, specify the -S suffix or utilize external mechanical switches.
Operating at 200 mm of travel, this cylinder remains well within standard stroke limits, though maintaining proper rod alignment is always recommended. For operations that must maintain a static position during a complete loss of air pressure, this standard SAI variant will drift; consider the SAIL pneumatic lock variant to prevent unintended load dropping.
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 SAI50BX200H FAQ
At an operating pressure of 0.5 MPa, 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 output rises to 1374 N.
Yes, the SAI50X200 is dimensionally interchangeable per ISO 15552 standards. It serves as a direct replacement for other ISO 15552 profile cylinders, provided you match the 50 mm bore, 200 mm stroke, and G1/4 PT port.
