About the Airtac SAI50 Standard Cylinder SAI50BX150SN
The AirTAC SAI50X150-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force and 825 N of pull force at 0.5 MPa. With a 50 mm bore and 150 mm stroke, this extruded aluminum barrel design provides a standardized mounting interface for seamless integration into existing setups.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and NBR seals for reliable wear performance. The integrated magnet (-S) allows for direct mounting of CMSE or DMSE sensor switches along the dual grooves on the barrel sides.

Where the Airtac SAI50 Standard Cylinder SAI50BX150SN Is Used
Clamping Mechanisms
Provides reliable 982 N clamping force at 0.5 MPa for securing workpieces during machining or assembly operations.
Product Diverting
Drives diverters and gates on packaging lines, utilizing the 150 mm stroke to route products efficiently.
Material Ejection
Ejects molded or stamped parts from machinery, benefiting from the durable NBR seals and SUS304 rod.
Is the Airtac SAI50 Standard Cylinder SAI50BX150SN the Right Cylinder?
Choose this 50 mm bore when an application requires stepping up from the 40 mm bore class, which provides 628 N at 0.5 MPa, to achieve greater thrust without the bulk of a 63 mm cylinder. The 150 mm stroke is well-suited for mid-range positioning tasks.
For load holding, remember that standard adjustable air cushions only decelerate the piston at stroke ends and do not prevent drift when air pressure is lost. If the system must maintain position without live pressure, consider the SAIL variant with an air-released lock. As a direct replacement, match the 50 mm bore, 150 mm stroke, PT tapered port, and required mounting accessory like an FA flange or LB foot.
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 SAI50BX150SN FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X150-S is dimensionally interchangeable per ISO 15552 standards. It serves as a direct replacement for other ISO 15552 profile cylinders when matching the 50 mm bore, 150 mm stroke, and PT port specifications.
