About the Airtac SAI50 Standard Cylinder SAI50AX475S
The AirTAC SAI50X475-S is a double-acting ISO 15552 profile cylinder engineered for applications requiring a 475 mm stroke. It generates 982 N of push force and 825 N of pull force at 0.5 MPa, making it well-suited for mid-range automation tasks. The extruded aluminum barrel eliminates tie-rods, providing a clean exterior that drops directly into standard ISO 15552 mounting footprints.
This specific configuration includes a magnet for position sensing, allowing seamless integration with CMSE or DMSE reed switches along the dual sensor grooves. It is built with an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance, and utilizes PT tapered port threads to ensure a robust pneumatic seal.

Where the Airtac SAI50 Standard Cylinder SAI50AX475S Is Used
Material Transfer
Pushes medium-weight packages or pallets along a 475 mm transfer distance with 982 N of thrust at 0.5 MPa.
Component Seating
Extends to press or seat mechanical parts into housings, utilizing the SUS420J2 rod for durability against minor axial stress.
Sorting Diverters
Actuates sorting arms or diverters on packaging lines, using the integrated magnet and CMSE sensors to confirm end-of-stroke positions.
Is the Airtac SAI50 Standard Cylinder SAI50AX475S the Right Cylinder?
Selecting this 50 mm bore over the smaller 40 mm version upgrades your thrust from 628 N to 982 N at 0.5 MPa, while stepping up to the 63 mm bore yields 1559 N if your payload demands more force. Because this model features a 475 mm stroke, the extended rod is susceptible to bending under side loads; utilizing external guide rails or a guided cylinder module is strongly recommended to prevent premature rod-bearing wear.
For direct compatibility, ensure your replacement matches the 50 mm bore, 475 mm stroke, G1/4 port size, and desired mounting accessories like FA flanges or TC trunnions. Remember that the standard double-acting SAI relies on continuous air pressure to move; it will not hold a load in place if air is exhausted. For fail-safe load holding, consider the SAIL variant with an air-released lock or an external rod lock.
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 SAI50AX475S FAQ
At an operating pressure of 0.5 MPa, this 50 mm bore cylinder provides a push force of 982 N and a pull force of 825 N. If pressure is increased to 0.7 MPa, the push force reaches 1374 N.
Yes, the SAI50X475-S is dimensionally interchangeable with other ISO 15552 profile cylinders. Ensure your setup matches the 50 mm bore, 475 mm stroke, and G1/4 port configuration for a seamless direct replacement.
