About the Airtac SAI50 Standard Cylinder SAI50X270
The AirTAC SAI50X270 is a double-acting ISO 15552 profile cylinder offering 982 N of push force at 0.5 MPa and 825 N of pull force. Its 270 mm stroke provides the extended travel needed for mid-range automation tasks. The extruded aluminum barrel design omits tie rods, maintaining a clean exterior while conforming to strict ISO mounting dimensions.
This specific configuration uses a standard carbon steel piston rod and PT tapered port threads. Since no magnet is specified, it operates without sensor tracks; add the -S suffix if you require CMSE or DMSE switch integration along the dual sensor grooves.

Where the Airtac SAI50 Standard Cylinder SAI50X270 Is Used
Package Diverting
Actuates diverter arms along packaging lines, utilizing the 270 mm stroke to push cartons cleanly into secondary lanes without lagging.
Component Ejection
Ejects molded or machined parts from press beds, using the 982 N push force at 0.5 MPa to clear heavy workpieces reliably.
Pallet Positioning
Stops or indexes empty pallets on gravity conveyors, providing enough pull force to reposition light loads accurately.
Is the Airtac SAI50 Standard Cylinder SAI50X270 the Right Cylinder?
If your application requires less force, stepping down to a 40 mm bore yields 628 N at 0.5 MPa, while an 80 mm bore provides 2513 N for heavier loads. Because this 270 mm stroke exceeds the 300 mm threshold, side-load and rod-bearing bending become a concern; use an external guide rail or a guided cylinder to prevent premature wear on the rod bearing.
As a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard cylinder matching this 50 mm bore, 270 mm stroke, PT port, and mounting accessory footprint. Note that a plain SAI does not hold its load when air pressure is lost; use the SAIL variant with an air-released lock for fail-safe position holding.
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 SAI50X270 FAQ
At 0.5 MPa, this cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X270 is dimensionally interchangeable per ISO 15552, meaning it matches the mounting interface, 50 mm bore, and 270 mm stroke of equivalent profile cylinders from other manufacturers.
