About the Airtac SAI50 Standard Cylinder SAI50X270S
The AirTAC SAI50X270-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 270mm stroke. It delivers a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for medium-duty handling tasks. This stroke length is optimal for automated clamping and lifting stations that require extended reach without occupying excessive footprint. Equipped with a standard -S magnet, this unit integrates seamlessly with CMSE and DMSE series sensor switches via the dual-side extruded aluminum barrel grooves for precise positioning feedback. The piston rod is constructed from carbon steel for robust daily operation, and it utilizes adjustable air cushions at both ends to dampen impact forces effectively.

Where the Airtac SAI50 Standard Cylinder SAI50X270S Is Used
Automated Clamping
Provides reliable 982 N clamping force at 0.5 MPa for securing workpieces during machining or welding operations.
Product Diverting
Uses the 270mm stroke to push products between parallel conveyor lanes in packaging and sorting lines.
Vertical Lifting
Elevates lightweight pallets or containers using the integrated -S magnet for precise height verification.
Is the Airtac SAI50 Standard Cylinder SAI50X270S the Right Cylinder?
When selecting this model, verify that the 982 N output at 0.5 MPa is sufficient for your load; if higher thrust is required, stepping up to the 63mm bore yields 1559 N under the same pressure. Because the 270mm stroke generates moderate side-load leverage, ensure the load is guided externally to prevent rod-bearing bending. For applications where air pressure might drop or be exhausted, remember that standard air cushions only decelerate the piston at stroke ends and do not lock the load—if static holding is required, consider the SAIL (air-released lock) variant or an external pilot-operated check valve. This cylinder offers true ISO 15552 mounting interface interchangeability, allowing direct replacement using existing PT G1/4 ports, FA/FB flanges, and -S magnet configurations.

- ✓ 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 SAI50X270S FAQ
At 0.5 MPa operating pressure, the SAI50X270-S 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 SAI50X270-S is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing setups using the same G1/4 PT port and standard FA/FB mounting flanges.
