About the Airtac SAI50 Standard Cylinder SAI50X210
The AirTAC SAI50X210 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 210 mm stroke provides the extended travel needed for mid-range positioning tasks. The extruded aluminum barrel design omits tie rods, offering a clean exterior that drops directly into standard ISO 15552 mounting footprints.
This configuration utilizes a standard carbon steel piston rod and PT tapered port threads. Because it lacks a built-in magnet, you would specify the -S option if your application requires position detection via DMSE or CMSE sensors along the dual barrel grooves.

Where the Airtac SAI50 Standard Cylinder SAI50X210 Is Used
Package Diverting
Actuates diverter arms on packaging lines to route boxes efficiently using 982 N of push force.
Clamp Actuation
Secures medium-sized workpieces during machining operations, utilizing the 210 mm stroke to clear the work area.
Pallet Stopping
Controls pallet flow on low-friction roller conveyors by extending a 50 mm bore stopper gate.
Is the Airtac SAI50 Standard Cylinder SAI50X210 the Right Cylinder?
Select this 50 mm bore when a 32 mm bore (402 N at 0.5 MPa) is insufficient but an 80 mm bore (2513 N at 0.5 MPa) would be physically oversized. At 210 mm of travel, the unsupported rod length increases, making the assembly susceptible to bending under side loads. Utilize external guide rails or a guided cylinder carriage to absorb lateral forces and protect the rod bearing.
As a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard cylinder matching these interface dimensions. Match your mounting hardware (FA flange, LB foot, or TC trunnion) and ensure your pneumatic plumbing matches the G1/4 PT ports. Note that standard air cushions only decelerate the piston at end-of-stroke and will not hold a load vertically if air pressure is lost; use a SAIL variant or external check valve for static 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.
Airtac SAI50 Standard Cylinder SAI50X210 FAQ
At 0.5 MPa operating pressure, the SAI50X210 generates 982 N of push force and 825 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 1374 N.
Yes. The SAI50X210 is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts matching the 50 mm bore interface, provided your porting matches the G1/4 PT threads.
