About the Airtac SAI50 Standard Cylinder SAI50X45
The AirTAC SAI50X45 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 45mm stroke. It delivers a robust push force of 982 N at 0.5 MPa, making it well-suited for short-trroke clamping and ejection tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration features a standard carbon steel piston rod and PT tapered port threads. Because no magnet is specified, it is built without sensor grooves being utilized for this configuration, though the profile inherently accommodates standard ISO 15552 mounting accessories across foot, flange, and trunnion styles.

Where the Airtac SAI50 Standard Cylinder SAI50X45 Is Used
Short-Stroke Clamping
Provides 982 N of clamping force at 0.5 MPa for holding sheet metal or wood components securely during machining or drilling operations.
Package Ejector
Ideal for pushing lightweight to medium packages off a conveyor belt with a fast, precise 45mm extension.
Gate Diverter
Actuates sorting gates on automated packaging lines where a compact stroke and reliable medium-force output are necessary.
Is the Airtac SAI50 Standard Cylinder SAI50X45 the Right Cylinder?
Choose this 50mm bore when a 40mm bore (628 N push at 0.5 MPa) is insufficient and you need a step up in thrust without jumping to the larger 63mm size (1559 N). The 45mm stroke is optimal for compact machinery where full extension is required quickly. If your mechanism must hold a load vertically without continuous air pressure, remember this standard cylinder will drift; you should specify the SAIL variant with an air-released lock or use an external pilot check valve.
For a direct ISO 15552 replacement, match the 50mm bore, 45mm stroke, G1/4 port, and your required mounting accessory. This non-magnetized version is ideal for applications where position sensing is not required.
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 SAI50X45 FAQ
At 0.5 MPa operating pressure, the SAI50X45 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, as a true ISO 15552 profile cylinder, its mounting dimensions are standardized. It serves as a direct replacement for any cylinder adhering to the ISO 15552 interface, provided the 50mm bore, 45mm stroke, and G1/4 port match your system.
