About the Airtac SAI50 Standard Cylinder SAI50AX900
The AirTAC SAI50X900 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 900mm stroke. It delivers a robust push force of 982 N at 0.5 MPa, making it highly suitable for long-travel linear motion tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists side impacts.
This specific configuration features an SUS420J2 stainless steel piston rod (option A), offering superior corrosion resistance compared to standard carbon steel. It utilizes PT tapered port threads and lacks a magnet, meaning it is optimized purely for actuation rather than position sensing.

Where the Airtac SAI50 Standard Cylinder SAI50AX900 Is Used
Material Handling
Drives long-stroke diverters and pushers on conveyor lines where a 900mm reach is required to shift products between lanes.
Automated Assembly
Moves components along extended transfer stations, utilizing the 982 N force to push carriers reliably.
Pallet Handling
Actuates lifting or positioning mechanisms in automated storage systems where full 900mm extension is needed.
Is the Airtac SAI50 Standard Cylinder SAI50AX900 the Right Cylinder?
A 900mm stroke is non-standard for the 50mm bore, requiring careful attention to side loads. At this length, the unsupported rod is highly susceptible to bending under lateral forces; always pair this cylinder with an external linear guide or use a guided cylinder to prevent rod-bearing damage. If your application requires less force, stepping down to a 40mm bore yields 628 N at 0.5 MPa. For heavier loads, a 63mm bore provides 1559 N.
This model uses PT tapered ports. As a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard cylinder sharing this mounting interface. Remember that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold a load. If pressure is lost, the rod will drift, so consider the SAIL variant for pneumatic locking.
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 SAI50AX900 FAQ
At an operating pressure of 0.5 MPa, the SAI50X900 delivers 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 does not hold position without live pressure. The adjustable air cushion only decelerates the piston at stroke end. For load holding, use the SAIL variant with an air-released lock or an external rod lock.
