About the Airtac SAI50 Standard Cylinder SAI50AX190S
The AirTAC SAI50X190-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 190 mm stroke provides the precise mid-range travel required for packaging and assembly machinery. As a genuine AirTAC component, it ensures reliable pneumatic performance.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid environments. It includes a built-in magnet (-S) for seamless integration with CMSE and DMSE series sensor switches, and utilizes PT tapered port threads for secure pneumatic connections.

Where the Airtac SAI50 Standard Cylinder SAI50AX190S Is Used
Component Assembly
Provides the 982 N push force needed to press bearings or pins into housings on automated production lines.
Package Diversion
The 190 mm stroke actuates diverter arms to route packages of varying sizes on material handling conveyors.
Product Ejection
Uses the integrated magnet with DMSE sensors to confirm ejection stroke completion before the machine cycle restarts.
Is the Airtac SAI50 Standard Cylinder SAI50AX190S the Right Cylinder?
If your application requires less force, stepping down to a 40 mm bore yields 628 N at 0.5 MPa, while upgrading to a 63 mm bore provides 1559 N for heavier payloads. Because this 190 mm stroke is under 300 mm, side-load bending is less severe, but external guides should still be used for heavy off-center loads.
This model is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 profile cylinders. To match this exact unit, specify a 50 mm bore, 190 mm stroke, PT port thread, and the -S magnet option. Note that the standard double-acting design does not hold position without live air pressure; use the SAIL variant if a pneumatic lock is required for safety.
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.
