About the Airtac SAI50 Standard Cylinder SAI50BX190S
The AirTAC SAI50X190-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. This 50 mm bore unit features a 190 mm stroke, making it a versatile choice for mid-range automation tasks. Because 190 mm is a non-standard stroke length for this series, it is produced as a made-to-order configuration to suit specialized machinery layouts.
Built with a SUS304 stainless steel rod (option B), this model provides excellent corrosion resistance for demanding environments. The -S suffix indicates an integrated magnet, allowing seamless operation with CMSE and DMSE sensor switches housed in the dual-side barrel grooves. Fluid connections use PT tapered threads, ensuring robust sealing in pneumatic systems.

Where the Airtac SAI50 Standard Cylinder SAI50BX190S Is Used
Mid-Force Assembly
Provides reliable 982 N thrust for actuating medium-duty press fits and joining operations on automated production lines.
Material Diverting
The 190 mm stroke and integrated magnet make it ideal for driving lane diverters and sorting gates where position confirmation is required.
Corrosive Environments
The SUS304 stainless steel rod excels in packaging lines or food processing areas where moisture and washdowns are common.
Is the Airtac SAI50 Standard Cylinder SAI50BX190S the Right Cylinder?
If your application requires less force, stepping down to a 40 mm bore yields 628 N at 0.5 MPa, while moving up to a 63 mm bore provides 1559 N for heavier loads. Since this 190 mm stroke is below the 300 mm threshold, standard rod-bearing bending is minimal, though external guides are always recommended if heavy off-center loads are present. For tasks that must maintain a position without continuous air pressure, this standard cylinder will drift; you should instead specify the SAIL variant with an air-released lock or an external pilot-operated check valve. As a dimensionally interchangeable ISO 15552 profile cylinder, it serves as a direct replacement for other ISO 15552 cylinders, matching the 50 mm bore, 190 mm stroke, PT port, and standard mounting accessories like FA flanges or TC trunnions.
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.
