About the Airtac SAI50 Standard Cylinder SAI50BX150
The AirTAC SAI50X150 is a double-acting ISO 15552 profile cylinder offering a 50mm bore and 150mm stroke. It provides a theoretical push force of 982N at 0.5 MPa, making it well-suited for medium-duty handling and positioning tasks.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance and includes PT threaded pneumatic ports. The extruded aluminum barrel includes integrated sensor grooves on both sides, allowing for straightforward position tracking when paired with magnet-equipped variants.

Where the Airtac SAI50 Standard Cylinder SAI50BX150 Is Used
Medium-Duty Clamping
Provides reliable 982N clamping force at 0.5 MPa for holding workpieces securely during machining or welding operations.
Package Diverting
The 150mm stroke is optimal for actuating diverter arms on conveyor lines to sort medium-weight packages.
Material Handling Gates
Offers the robust push and pull force necessary to repeatedly open and close heavy safety gates or machine doors.
Is the Airtac SAI50 Standard Cylinder SAI50BX150 the Right Cylinder?
If your application requires slightly less force, stepping down to the 40mm bore yields 628N at 0.5 MPa, while moving up to the 63mm bore provides 1559N for heavier loads. Because the 150mm stroke is under 300mm, side-load bending stress on the rod bearing is minimal.
As a standard double-acting cylinder, this model relies on continuous air pressure to hold its load. If power or air is lost, the piston will drift. For applications requiring true position holding without live pressure, consider the SAIL (air-released lock) variant or an external rod lock. This unit is dimensionally interchangeable per ISO 15552 standards, requiring a 50mm bore, 150mm stroke, G1/4 port, and your choice of mounting accessory like an FA flange or TC trunnion.
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.
