About the Airtac SAI63 Standard Cylinder SAI63X35
The AirTAC SAI63X35 is a double-acting ISO 15552 profile cylinder with a 63mm bore and 35mm stroke. It provides 1559N of push force at 0.5MPa, making it a robust choice for short, powerful linear movements. The extruded aluminum barrel design omits tie rods, providing a clean exterior.
This model features standard carbon steel piston rod material and PT tapered port threads. For applications requiring position feedback, the barrel includes dual sensor grooves on both sides for CMSE or DMSE switches, though a magnet must be specified (-S) for detection.

Where the Airtac SAI63 Standard Cylinder SAI63X35 Is Used
Part Ejection
Short 35mm stroke rapidly pushes finished metal parts out of a machining center using 1559N of force.
Flow Diverter
Actuates a short diverter gate on a packaging line to route boxes without taking up excessive mounting length.
Pallet Clamping
Secures light pallets or workpieces in position during transfer operations within a compact fixture space.
Is the Airtac SAI63 Standard Cylinder SAI63X35 the Right Cylinder?
Choose this 63mm bore when 50mm (982N at 0.5MPa) lacks the necessary thrust, but you want to avoid the larger 80mm (2513N at 0.5MPa) footprint. The 35mm stroke is ideal for compact clamping or ejecting tasks.
As an ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders. If the machinery requires holding a load without continuous air pressure, note that the standard SAI piston will drift; use the SAIL (air-released lock) or BSAI (clamp-lock) variants for secure braking.
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.
