About the Airtac SAI50 Standard Cylinder SAI50BX260
The AirTAC SAI50X260 is a double-acting ISO 15552 profile cylinder offering 982 N of push force at 0.5 MPa. Its 260 mm stroke is well-suited for mid-range linear actuation tasks requiring reliable and consistent movement. The extruded aluminum barrel design eliminates tie-rods, providing a clean exterior that resists mechanical interference.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance, making it ideal for environments with moisture or light chemical exposure. It uses PT tapered port threads. Note that this unit is supplied without a magnet; if position sensing is required, an -S variant with CMSE or DMSE sensors must be specified instead.

Where the Airtac SAI50 Standard Cylinder SAI50BX260 Is Used
Package Diverting
Provides the necessary reach and 982 N of force at 0.5 MPa to push heavy cartons off a main conveyor belt onto sorting chutes.
Component Ejection
Ejects molded or machined parts from a press fixture using its 260 mm stroke, with the SUS304 rod offering resilience in humid shop environments.
Pallet Stop Gate
Acts as a pneumatic stop gate on a low-profile pallet accumulation line, extending to halt pallets before a wrapping station.
Is the Airtac SAI50 Standard Cylinder SAI50BX260 the Right Cylinder?
Selecting this 50 mm bore cylinder makes sense when 40 mm bore units (providing 628 N at 0.5 MPa) lack sufficient thrust, but stepping up to a 63 mm bore (1559 N at 0.5 MPa) would be excessive. The 260 mm stroke provides ample travel distance for pushing, lifting, or clamping operations.
Because this stroke exceeds 300 mm is not the case here, standard side-load considerations are moderate, but external guides are still recommended for heavy off-center loads. If your application requires the load to remain firmly in place after air pressure is removed or exhausted, do not rely on the adjustable air cushions, as they only decelerate the piston near stroke end. Instead, utilize the SAIL variant with an air-released lock or an external pilot-operated check valve. This model is dimensionally interchangeable with other ISO 15552 cylinders, accepting standard FA/FB flanges or TC trunnion mounts.
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.
