About the Airtac SAI50 Standard Cylinder SAI50AX145S
The AirTAC SAI50X145-S is a double-acting ISO 15552 profile cylinder offering a 50mm bore and 145mm stroke. It generates 982N of push force and 825N of pull force at 0.5 MPa, making it well-suited for medium-duty handling tasks.
This specific configuration includes a SUS420J2 stainless steel rod for enhanced corrosion resistance and a built-in magnet for use with CMSE or DMSE sensor switches. The extruded aluminum barrel features sensor grooves on both sides, and the PT tapered port ensures a robust pneumatic connection.

Where the Airtac SAI50 Standard Cylinder SAI50AX145S Is Used
Material Diversion
Ideal for actuating medium-duty diverter arms on packaging lines, utilizing the 145mm stroke to route products efficiently.
Vertical Lifting
Provides reliable upward push force for lifting tote bins or pallets in automated storage and retrieval systems.
Part Clamping
Holds workpieces securely during machining or assembly operations, taking advantage of the 825N pull force at 0.5 MPa.
Is the Airtac SAI50 Standard Cylinder SAI50AX145S the Right Cylinder?
If your application requires less force, stepping down to a 40mm bore yields 628N at 0.5 MPa; conversely, moving up to a 63mm bore provides 1559N. For this 145mm stroke, side-load stress on the rod bearing is moderate, but external guides are recommended if heavy or off-center loads are present.
As a true ISO 15552 profile cylinder, this model is dimensionally interchangeable with other ISO 15552 cylinders. Remember that the adjustable air cushions only decelerate the piston at stroke ends; they do not hold a load. If position holding without air pressure is needed, consider the SAIL lock variant 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 SAI50AX145S FAQ
