About the Airtac SAI50 Standard Cylinder SAI50X900S
The AirTAC SAI50X900-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 900mm stroke. It generates 982N of push force and 825N of pull force at 0.5 MPa, making it well-suited for long-travel material handling and positioning tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists debris accumulation.
This specific configuration includes a magnetic piston for non-contact position sensing using CMSE or DMSE series switches housed in the dual-side sensor grooves. The standard carbon steel piston rod offers robust durability for industrial automation, while the -S magnet option ensures seamless integration into modern PLC-controlled systems.

Where the Airtac SAI50 Standard Cylinder SAI50X900S Is Used
Long-Stroke Material Transfer
Ideal for pushing pallets or products between adjacent conveyor lines over extended distances up to 900mm.
Automated Storage Retrieval
Drives vertical or horizontal extraction mechanisms in automated storage systems where precise 982N force is needed.
Large Door Actuation
Opens and closes heavy machine safety doors or guarding panels, utilizing the full 900mm travel distance.
Is the Airtac SAI50 Standard Cylinder SAI50X900S the Right Cylinder?
Selecting this 50mm bore model provides a balanced output of 982N at 0.5 MPa, sitting neatly between the lighter 40mm bore (628N) and the heavier 63mm bore (1559N) options. The 900mm stroke is excellent for long transfers, but an unsupported rod of this length is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external linear guide rail or use a fully guided cylinder design.
As a standard double-acting cylinder, the SAI50X900-S relies on live air pressure to hold its position. If your application requires the load to remain fixed during an air supply failure or valve centering, the standard SAI will drift. For positive holding, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. This model is dimensionally interchangeable per ISO 15552, featuring a PT tapered G1/4 port, and can be paired with FA or FB flange mounts.
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.
