About the Airtac SAI50 Standard Cylinder SAI50X900
The AirTAC SAI50X900 is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 982 N and a pull force of 825 N at 0.5 MPa. Its extruded aluminum barrel design omits tie rods, providing a smooth exterior that integrates seamlessly into modern automated machinery.
This 900 mm stroke configuration is equipped with a standard carbon steel piston rod and utilizes a PT tapered port thread for reliable pneumatic connectivity. For applications requiring end-of-stroke position feedback, the barrel features dual-sided sensor grooves ready to accept CMSE or DMSE switches when a magnet is specified.

Where the Airtac SAI50 Standard Cylinder SAI50X900 Is Used
Long-Reach Transfer
Pushes products across a 900 mm gap between conveyor sections, utilizing the 982 N push force to move heavy totes without stalling.
High-Bay Extraction
Extracts pallets from deep storage racks where the extended stroke is necessary to reach past the pallet face.
Material Distribution
Actuates a diverter arm over a 900 mm travel distance to route workpieces to secondary machining stations.
Is the Airtac SAI50 Standard Cylinder SAI50X900 the Right Cylinder?
Selecting this 50 mm bore unit makes sense when a 40 mm bore (providing 628 N push at 0.5 MPa) is insufficient, but an 80 mm bore (2513 N push) would be excessive. At 900 mm of stroke, the unsupported rod length is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, mount this cylinder using a trunnion accessory and guide the load externally.
Because it is a standard double-acting actuator, the SAI50X900 will drift if air pressure is lost or a valve is centered. It cannot hold a suspended load mechanically. For vertical applications requiring safety locking without live pressure, specify the SAIL variant with an integrated air-released lock. As a dimensionally interchangeable ISO 15552 cylinder, replacement requires matching the 50 mm bore, 900 mm stroke, PT port, and mounting footprint.
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 SAI50X900 FAQ
At an operating pressure of 0.5 MPa, this 50 mm bore 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.
Yes, the SAI50X900 is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement by matching the 50 mm bore, 900 mm stroke, and PT port specifications.
