About the Airtac SAI50 Standard Cylinder SAI50AX260S
The AirTAC SAI50X260-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 260mm stroke. It delivers a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for mid-range industrial handling tasks.
This specific configuration includes a SUS420J2 stainless steel rod for enhanced corrosion resistance and a PT tapered port thread. The -S suffix indicates an integrated magnet, allowing seamless operation with CMSE and DMSE sensor switches housed in the dual-side barrel grooves.

Where the Airtac SAI50 Standard Cylinder SAI50AX260S Is Used
Component Clamping
Provides reliable 982 N clamping force at 0.5 MPa for securing mid-weight machined parts during milling or drilling operations.
Package Diverting
The 260mm stroke offers ample reach for pushing and sorting standard totes or packages across automated conveyor belts.
Pallet Lift Gates
Actuates lifting mechanisms on pallet transfer stations, utilizing the integrated magnet for precise end-of-stroke confirmation.
Is the Airtac SAI50 Standard Cylinder SAI50AX260S the Right Cylinder?
If your application requires less force, stepping down to a 40mm bore yields 628 N at 0.5 MPa, while moving up to a 63mm bore provides 1559 N for heavier demands. Because this 260mm stroke exceeds 300mm, it is critical to manage side loads; use an external guide rail or a guided cylinder to prevent rod-bearing bending and premature seal wear.
As a direct replacement per ISO 15552 mounting dimensions, it matches a 50mm bore, 260mm stroke, PT G1/4 port, and standard FA/FB flange or TC trunnion accessories. Note that this standard cylinder relies on live air pressure to move; it cannot hold a load if air is exhausted. For position holding without pressure, consider the SAIL locking variant.
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 SAI50AX260S FAQ
