About the Airtac SAI50 Standard Cylinder SAI50X300S
The AirTAC SAI50X300-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 300mm stroke. It delivers a push force of 982 N at 0.5 MPa, extending to 1374 N at 0.7 MPa, making it a robust choice for medium-duty handling. The extruded aluminum barrel design omits tie rods, providing a clean exterior while maintaining strict dimensional interchangeability with other ISO 15552 actuators.
Equipped with a -S magnet, this unit supports CMSE and DMSE sensor switches via integrated grooves on both sides of the barrel. The standard carbon steel piston rod offers reliable durability for general industrial automation, while adjustable air cushions at both ends manage end-of-stroke impact. Threaded PT ports ensure a secure, tapered pneumatic connection.

Where the Airtac SAI50 Standard Cylinder SAI50X300S Is Used
Material Diverting
Ideal for actuating diverter arms on packaging lines where the 982 N force at 0.5 MPa easily pushes medium-weight cartons onto secondary chutes.
Assembly Pressing
Provides consistent downward pressure for pressing small bushings or pins into housings, utilizing adjustable cushions to soften the end stroke.
Vertical Lifting Gates
Drives horizontal sliding safety gates on automated storage systems, using dual sensor grooves to track fully open and closed positions.
Is the Airtac SAI50 Standard Cylinder SAI50X300S the Right Cylinder?
Stepping down to a 40mm bore reduces the 0.5 MPa push force to 628 N, whereas moving up to a 63mm bore increases it to 1559 N. For this 300mm stroke, side load is a primary concern; long unsupported rods are prone to bending under lateral forces. To protect the rod bearing and prevent premature wear, utilize an external guide rail or select a guided cylinder assembly.
This model is a direct replacement for any ISO 15552 cylinder matching a 50mm bore, 300mm stroke, and G1/4 port. It utilizes a standard carbon steel rod and includes the -S magnet option for position sensing. If an application requires the load to stay fixed when air pressure is removed, a plain SAI will drift; consider the SAIL pneumatic lock variant or an external rod lock for fail-safe 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 SAI50X300S FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. If you increase the operating pressure to 0.7 MPa, the push force rises to 1374 N.
Yes, the SAI50X300-S is a genuine ISO 15552 profile cylinder. As long as the competing actuator shares the same 50mm bore, 300mm stroke, and G1/4 port interface, it will mount as a direct replacement.
