About the Airtac SAI63 Standard Cylinder SAI63X95
The AirTAC SAI63X95 is a double-acting ISO 15552 profile cylinder engineered for standardized mounting. Delivering a push force of 1559 N at 0.5 MPa, this 63 mm bore unit is built to handle demanding industrial actuation. The 95 mm stroke provides a compact extension length for mid-range tasks. A standard carbon steel piston rod offers high tensile strength for reliable everyday operation.
This model features an extruded aluminum barrel without tie-rods, incorporating sensor grooves on both sides for straightforward position detection. If your environment involves high temperatures, you can specify Viton (H) seals instead of the standard TPU to maintain sealing integrity. It uses a PT tapered port thread and operates efficiently between 30-800 mm/s.

Where the Airtac SAI63 Standard Cylinder SAI63X95 Is Used
Clamping Fixtures
Provides robust 1559 N clamping force at 0.5 MPa to secure heavy metal components during machining operations.
Product Diverters
Uses its 95 mm stroke to push packages rapidly across sorting lines without taking up excessive machine footprint.
Press Operations
Drives small pneumatic presses for light assembly tasks, benefiting from the adjustable air cushions at both stroke ends.
Is the Airtac SAI63 Standard Cylinder SAI63X95 the Right Cylinder?
Select this 63 mm bore when a 50 mm bore falls short—yielding 982 N at 0.5 MPa—and before stepping up to the heavier 80 mm bore which provides 2513 N. The 95 mm stroke is optimal for short, powerful transfers. Because the stroke is under 300 mm, rod-bearing bending is minimal, though external guides should still be used for heavy lateral loads.
This SAI variant is dimensionally interchangeable per ISO 15552, making it a drop-in replacement for other ISO 15552 profile cylinders. Ensure you match the G3/8 PT port, appropriate mounting accessory (like an FA flange or TC trunnion), and add the -S magnet if position sensing is required. Note that standard models do not hold position upon air loss; for dead-load holding, consider the SAIL lock variant.
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 SAI63 Standard Cylinder SAI63X95 FAQ
