About the Airtac SAI63 Standard Cylinder SAI63BX450S
The AirTAC SAI63X450-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 450mm stroke. It generates 1559 N of push force and 1402 N of pull force at 0.5 MPa, making it well-suited for medium-duty automation tasks requiring a long linear reach.
This specific configuration includes a SUS304 stainless steel piston rod for superior corrosion resistance in harsh environments. It also features a built-in magnet (-S) for use with CMSE and DMSE proximity sensors, which mount directly into the dual-sided extruded barrel grooves.

Secures large workpieces on CNC fixtures where the stainless rod resists coolant splashing.
Pallet Handling
Positions and sorts heavy tote boxes in automated storage and retrieval systems.
Is the Airtac SAI63 Standard Cylinder SAI63BX450S the Right Cylinder?
Choose this 63mm bore when a 50mm bore falls short—providing 982 N at 0.5 MPa versus the 63mm's 1559 N. If your application requires less force, stepping down to the 40mm bore yields 628 N. The 450mm stroke provides ample extension but demands careful mounting to prevent rod-bearing bending under side loads. For long-stroke setups like this, utilize an external guide rail or a guided cylinder to absorb lateral forces and prevent premature wear.
This model uses PT tapered ports (G3/8) and includes a magnet for position sensing. If your machinery requires the load to remain safely suspended or fixed during a pressure loss, note that the standard adjustable air cushions only decelerate the piston at stroke ends. For true locking capability, specify the SAIL (pneumatic lock) or BSAI (clamp-lock) variant instead of relying on the base cylinder.
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.
