Where the Airtac SAI63 Standard Cylinder SAI63AX190 Is Used
Automated Clamping
Provides robust 1559 N clamping force at 0.5 MPa for securing heavy metal components during machining operations.
Material Diverting
Drives heavy-duty diverter arms on conveyor lines, utilizing the 190 mm stroke to redirect products efficiently.
Press Operations
Powers small pneumatic presses requiring consistent mid-stroke force and reliable double-acting cycling.
Is the Airtac SAI63 Standard Cylinder SAI63AX190 the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore (982 N push at 0.5 MPa) lacks the necessary thrust, but before stepping up to an 80 mm unit (2513 N). For applications requiring position holding without continuous air pressure, select the SAIL or BSAI variant.
To match this ISO 15552 cylinder for a drop-in replacement, verify the 63 mm bore, 190 mm stroke, G3/8 PT port, required mounting accessory (like TC trunnion or FA flange), and whether a magnet (-S) is needed for sensor tracking.
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.
