About the Airtac SAI50 Standard Cylinder SAI50AX90
The AirTAC SAI50X90 is a double-acting ISO 15552 profile cylinder offering a push force of 982 N at 0.5 MPa and a pull force of 825 N. With a 50 mm bore and 90 mm stroke, it provides a compact footprint for mid-range automation tasks. The extruded aluminum barrel design eliminates tie-rods, ensuring a clean exterior.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid environments. It utilizes PT tapered port threads and does not include a magnet, meaning it is optimized for purely mechanical actuation without sensor feedback.

Where the Airtac SAI50 Standard Cylinder SAI50AX90 Is Used
Short-Stroke Clamping
Provides 982 N of clamping force at 0.5 MPa, ideal for securing medium-sized workpieces during machining or welding operations.
Package Diverting
The 90 mm stroke quickly actuates diverters and gates on packaging lines, moving products between parallel conveyor belts.
Pneumatic Ejection
Delivers rapid, repetitive ejection of molded or stamped parts from machinery, utilizing the 30-800 mm/s speed range.
Is the Airtac SAI50 Standard Cylinder SAI50AX90 the Right Cylinder?
Select this 50 mm bore model when a 40 mm bore (628 N push at 0.5 MPa) is insufficient but a 63 mm bore (1559 N push at 0.5 MPa) is physically too large. The 90 mm stroke is ideal for short-travel clamping and lifting. Because this standard SAI50X90 lacks a magnet, it cannot host CMSE or DMSE cylinder switches; if your application requires position sensing, specify the -S option.
This cylinder does not hold its load if air pressure is removed or exhausted; the piston will drift. For vertical loads requiring safety during pressure loss, integrate an external pilot-operated check valve or select the SAIL variant with an air-released lock. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke.
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.
