About the Airtac SAI50 Standard Cylinder SAI50X50H
The AirTAC SAI50X50 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 50mm stroke. It provides a thrust of 982 N at 0.5 MPa, making it well-suited for compact, high-force clamping and positioning tasks.
This unit is configured with high-temperature Viton (FKM) seals, expanding the operating envelope beyond standard TPU to handle hotter industrial environments. The extruded aluminum barrel lacks tie-rods and features dual sensor grooves for direct CMSE or DMSE switch mounting.

Where the Airtac SAI50 Standard Cylinder SAI50X50H Is Used
Hot Metal Clamping
Viton seals tolerate elevated ambient temperatures near warm workpieces, securing 50mm strokes during machining or weld clamping.
Diversion Gates
Provides 982 N of force at 0.5 MPa to snap conveyor sorting flaps into position rapidly under continuous cycling.
Product Ejection
Short 50mm stroke delivers rapid knockout force to eject molded parts or stamped components from press beds.
Is the Airtac SAI50 Standard Cylinder SAI50X50H the Right Cylinder?
At 0.5 MPa this 50mm bore yields 982 N of push force; step down to a 40mm bore for 628 N if payload is lighter, or move up to 63mm for 1559 N. The PT tapered port threads ensure a robust pneumatic connection.
Because the standard SAI lacks a locking mechanism, exhaust or pressure loss will cause the piston to drift. Use the SAIL variant or an external rod lock if the application demands fail-safe load 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.
