About the Airtac SAI50 Standard Cylinder SAI50AX300
The AirTAC SAI50X300 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 300 mm stroke provides the extended travel needed for mid-range material handling and automated positioning tasks.
Built with a SUS420J2 stainless steel piston rod and PT tapered port threads, this model ensures robust corrosion resistance and leak-free pneumatic connections. The extruded aluminum barrel features dual sensor grooves, allowing for straightforward position tracking when paired with magnetic switches on -S variants.

Where the Airtac SAI50 Standard Cylinder SAI50AX300 Is Used
Package Diverting
Extends 300 mm to push medium-weight cartons off a main conveyor line with reliable 982 N thrust.
Pallet Stopper
Acts as an extended physical barrier to halt pallets at a staging area before they enter the wrapping station.
Gate Actuation
Provides the long throw necessary to open and close safety guarding or access doors on automated machining centers.
Is the Airtac SAI50 Standard Cylinder SAI50AX300 the Right Cylinder?
Selecting this 50 mm bore is ideal when a 40 mm bore (628 N at 0.5 MPa) lacks the necessary thrust, but a 63 mm bore (1559 N) would be physical overkill. Because this model features a 300 mm stroke, the extended unsupported rod is susceptible to bending under lateral loads; always utilize external guide rails or a guided cylinder to prevent rod-bearing damage.
As a standard double-acting cylinder, it relies on continuous air pressure to maintain its position. If your workflow requires the piston to resist drifting or dropping upon loss of air pressure, integrate an external pilot-operated check valve or select the SAIL locking variant. For direct replacements, match the 50 mm bore, 300 mm stroke, G1/4 port, and your required mounting accessories like the FA flange or LB foot.
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 SAI50AX300 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 1374 N.
No, the standard SAI50X300 cannot hold a load without constant air pressure. The adjustable air cushions only decelerate the piston at stroke end. For dead-load holding, use an external rod lock or the AirTAC SAIL variant.
