About the Airtac SAI50 Standard Cylinder SAI50AX150S
The AirTAC SAI50X150-S is a double-acting ISO 15552 profile cylinder featuring a 50 mm bore and 150 mm stroke. It generates 982 N of push force and 825 N of pull force at 0.5 MPa, making it well-suited for mid-range automation tasks requiring reliable linear motion.
This specific configuration includes a SUS420J2 stainless steel rod for enhanced corrosion resistance and a built-in magnet for use with CMSE and DMSE series sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the ports utilize a PT tapered thread design.

Where the Airtac SAI50 Standard Cylinder SAI50AX150S Is Used
Parts Clamping
Ideal for securely holding workpieces during machining or assembly operations using its 982 N push force.
Package Diverting
The 150 mm stroke provides ample reach for pushing and sorting medium-sized cartons on automated conveyor lines.
Gate Control
Operates safety guards and access gates on automated machinery, benefiting from the durable SUS420J2 rod.
Is the Airtac SAI50 Standard Cylinder SAI50AX150S the Right Cylinder?
If your application requires less force, stepping down to the 40 mm bore yields 628 N at 0.5 MPa, while moving up to the 63 mm bore provides 1559 N for heavier loads. Because this 150 mm stroke is under 300 mm, rod bearing bending is minimal, though external guides should still be used for significant lateral loads.
This model serves as a dimensionally interchangeable direct replacement for other ISO 15552 profile cylinders. To match this exact configuration, select the 50 mm bore, 150 mm stroke, PT port thread, and include the -S magnet option. Remember that standard SAI cylinders rely on live air pressure to hold position; if power is lost, the piston will drift. For failsafe load holding, consider the SAIL or BSAI variant.
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.
