About the Airtac SAI50 Standard Cylinder SAI50X260S
The AirTAC SAI50X260-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 260mm stroke. It provides a robust push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for mid-range automation tasks. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
Equipped with a magnet for position sensing, this unit seamlessly integrates CMSE or DMSE reed switches along the dual sensor grooves machined into both sides of the barrel. The standard carbon steel piston rod offers high tensile strength for industrial cycling, while the tapered PT G1/4 port ensures a tight, reliable pneumatic connection.

Where the Airtac SAI50 Standard Cylinder SAI50X260S Is Used
Package Diverting
Provides the 982 N push force needed to actuate routing gates on high-speed packaging conveyors.
Component Clamping
Holds medium-weight metal or composite parts securely in place during light machining and assembly.
Pallet Stopping
Acts as a reliable stop mechanism for loaded pallets accumulating at robotic pickup stations.
Is the Airtac SAI50 Standard Cylinder SAI50X260S the Right Cylinder?
If your application requires slightly less thrust, stepping down to a 40mm bore yields 628 N of push force at 0.5 MPa, whereas upgrading to a 63mm bore provides 1559 N for heavier loads. Because this 260mm stroke generates extended rod overhang, operating at high speeds or under lateral stress can cause rod-bearing bending; utilizing an external guide rail or a fully guided cylinder is strongly recommended to prevent premature wear.
This model is a direct replacement for any ISO 15552 cylinder matching the 50mm bore, 260mm stroke, and G1/4 port configuration. Be aware that the adjustable air cushions at both stroke ends only decelerate the piston; they do not hold a load. If pressure is lost, the rod will drift, so deploy an external pilot-operated check valve for 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 SAI50X260S FAQ
At an operating pressure of 0.5 MPa, this double-acting cylinder generates a push force of 982 N and a pull force of 825 N. At 0.7 MPa, the push force increases to 1374 N.
No, the standard SAI cylinder cannot hold a load if air pressure is lost. The adjustable air cushions only decelerate the piston at the end of the stroke. For dead-load holding, use an external rod lock or pilot-operated check valve.
