About the Airtac SAI50 Standard Cylinder SAI50X210S
The AirTAC SAI50X210-S is a double-acting ISO 15552 profile cylinder with a 50mm bore and 210mm stroke. It generates 982 N of push force at 0.5 MPa, making it a solid choice for medium-duty handling tasks. The extruded aluminum barrel includes sensor grooves on both sides, and the -S suffix means a magnet is pre-installed for CMSE and DMSE reed switches.
This unit features a standard carbon steel piston rod and PT tapered port threads. As a genuine AirTAC component, it provides a direct replacement for any ISO 15552 mounting interface without relying on external tie-rods.

Where the Airtac SAI50 Standard Cylinder SAI50X210S Is Used
Component Clamping
Provides reliable clamping force for medium-sized workpieces during machining or welding operations.
Package Diverting
Extends 210mm to push and divert packages on a sorting line with responsive actuation.
Material Ejection
Ejects molded or stamped parts from machinery, utilizing the 982 N push force at 0.5 MPa.
Is the Airtac SAI50 Standard Cylinder SAI50X210S the Right Cylinder?
Select this 50mm bore when a 32mm bore (402 N push at 0.5 MPa) is insufficient and a 63mm bore (1559 N) would be excessive. The 210mm stroke is non-standard but falls within the 1200mm maximum limit. Because the stroke exceeds 300mm, be mindful of side-load; an unsupported rod can bend under lateral forces, so use an external guide or a guided cylinder carriage for heavy off-center loads.
This model uses PT ports and a carbon steel rod. It is dimensionally interchangeable per ISO 15552. If your application requires holding a load without live air pressure, note that the standard adjustable air cushion only decelerates the piston and does not lock it; consider the SAIL or BSAI variants 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.
