About the Airtac SAI50 Standard Cylinder SAI50X260
The AirTAC SAI50X260 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 260mm stroke. It provides a push force of 982 N at 0.5 MPa and a pull force of 825 N, making it well-suited for medium-duty handling tasks that require a moderate extension length.
This model comes equipped with a standard carbon steel piston rod and utilizes a PT tapered port thread. For environments requiring high-temperature resistance, the seal options can be upgraded to Viton (H). Furthermore, if your setup requires end-of-stroke signaling, you can specify the -S magnet option to utilize CMSE or DMSE sensors in the dual side grooves.

Where the Airtac SAI50 Standard Cylinder SAI50X260 Is Used
Package Diverting
Ideal for pushing packages between adjacent conveyor belts with its 260mm reach and 982N thrust at 0.5 MPa.
Clamping Fixtures
Provides reliable holding force for medium-sized machining or welding fixtures, utilizing adjustable air cushions at both ends for smooth stops.
Material Lift Gates
Actuates lightweight lift gates or sorting flaps in automated warehousing systems where a 260mm extension is required.
Is the Airtac SAI50 Standard Cylinder SAI50X260 the Right Cylinder?
When selecting this cylinder, consider your force requirements carefully: stepping down to a 40mm bore yields 628 N of push force at 0.5 MPa, while upgrading to a 63mm bore provides 1559 N. For this 260mm stroke, side loads can induce bending forces on the rod bearing; utilizing an external guide rail or a guided cylinder module is recommended to prevent premature wear.
This unit is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other standard profile cylinders with matching 50mm bore, 260mm stroke, PT G1/4 port, and compatible mounting accessories like FA flange or TC trunnion. Note that the standard SAI does not hold loads when air pressure is removed; for position holding without live pressure, consider the SAIL air-released lock variant or an external pilot-operated check valve.
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 SAI50X260 FAQ
