About the Airtac SAI50 Standard Cylinder SAI50AX25
The AirTAC SAI50X25 is a double-acting ISO 15552 profile cylinder engineered for short-stroke actuation. Delivering a push force of 982 N at 0.5 MPa, this 50 mm bore unit is ideal for high-cycle clamping and ejecting tasks where space is restricted.
This configuration features an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It utilizes PT tapered port threading and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches is not supported without modification.

Where the Airtac SAI50 Standard Cylinder SAI50AX25 Is Used
Short-Stroke Clamping
Provides robust 982 N clamping force at 0.5 MPa for holding sheet metal or composite parts during machining and welding operations.
Product Ejection
Ideal for rapidly pushing lightweight finished goods off conveyor lines in packaging machinery where a 25 mm travel distance is sufficient.
Gate Diverter
Powers short-acting diverter gates on material handling systems, quickly routing boxes or parts into secondary processing lanes.
Is the Airtac SAI50 Standard Cylinder SAI50AX25 the Right Cylinder?
Select this 50 mm bore model when a 32 mm bore (402 N push at 0.5 MPa) lacks the necessary thrust, but a 63 mm bore (1559 N push at 0.5 MPa) would be physically oversized for the machine envelope. The 25 mm stroke provides rapid, short movements.
As an ISO 15552 profile cylinder, it serves as a direct replacement for other ISO 15552 cylinders utilizing identical mounting dimensions and accessories like FA flanges or LB foot brackets. Because it is a standard double-acting cylinder, it will not hold a load if air pressure is lost; for position holding without live pressure, consider the SAIL locking variant or an external pilot-operated check valve.
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 SAI50AX25 FAQ
At an operating pressure of 0.5 MPa, the SAI50X25 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 SAI50X25 is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement for other ISO 15552 profile cylinders using the same mounting interface and PT G1/4 ports.
