About the Airtac SAI50 Standard Cylinder SAI50X25
The AirTAC SAI50X25 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 25mm stroke. It generates a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for short, high-force clamping and positioning tasks. The extruded aluminum barrel omits tie rods, presenting a clean exterior that speeds up machine cleaning.
Beyond the standard spec table, this unit ships with a carbon steel piston rod for robust structural integrity in industrial environments. The barrel incorporates dual sensor grooves for direct CMSE or DMSE switch mounting, though adding a magnet requires specifying the -S option at order.

Where the Airtac SAI50 Standard Cylinder SAI50X25 Is Used
Short-Stroke Clamping
Ideal for holding metal workpieces firmly in a machining fixture using its 982 N push force over a compact 25mm travel.
Package Diverter
Provides rapid, short-actuation routing of packages on a conveyor line where space is restricted but firm contact is needed.
Press Assembly
Executes precise pressing and insertion of small bearings or pins into housings on automated assembly lines.
Is the Airtac SAI50 Standard Cylinder SAI50X25 the Right Cylinder?
Select this 50mm bore when a 40mm bore falls short of the required 628 N push force at 0.5 MPa, but avoid stepping up to the 63mm bore unless you specifically need its 1559 N output. The 25mm stroke is optimal for compact, rapid actuation. Because the stroke is short, side-load stress on the rod bearing is minimal, but you should still ensure the load is axially aligned to prevent premature seal wear.
For replacements, verify the 50mm bore, 25mm stroke, PT G1/4 port, and your required mounting accessory, such as an FA flange or LB foot. Note that standard SAI cylinders drift when air pressure is removed; if your application demands static position holding without live pressure, consider the SAIL locking 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.
