About the Airtac SAI63 Standard Cylinder SAI63BX50
The AirTAC SAI63X50 is a double-acting ISO 15552 profile cylinder engineered for robust linear motion. Delivering a push force of 1559 N at 0.5 MPa, this 63 mm bore unit features a short 50 mm stroke ideal for high-force clamping and ejecting in confined spaces. The extruded aluminum barrel eliminates tie-rods, providing a clean profile that drops directly into standard ISO 15552 mounting interfaces.
Built for demanding environments, this specific configuration utilizes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance. Fluid ports feature PT tapered threading, and the barrel incorporates dual-side sensor grooves. While standard models omit a magnet, adding the -S option enables CMSE or DMSE reed switch integration for position sensing.

Where the Airtac SAI63 Standard Cylinder SAI63BX50 Is Used
Short-Stroke Pressing
Provides 1559 N of push force at 0.5 MPa for seating bearings and stamping small components in automated assembly lines.
Heavy Part Ejection
Uses the 50 mm stroke to rapidly push finished metal or plastic parts off a conveyor without occupying excessive machine length.
Pallet Clamping
Secures heavy pallets or fixtures during machining or wrapping operations where a compact 63 mm bore delivers necessary holding power.
Is the Airtac SAI63 Standard Cylinder SAI63BX50 the Right Cylinder?
Selecting the SAI63X50 is optimal when an application requires substantial force within a minimal footprint. If your push requirements fall below 1000 N at 0.5 MPa, stepping down to the 50 mm bore variant saves space and air consumption. Conversely, operations needing more than 2182 N at 0.7 MPa should evaluate the 80 mm bore size. This 50 mm stroke excels in short, rapid movements.
Because standard pneumatic cylinders exhaust air when unpowered, the piston will drift if pressure is lost; this model cannot hold a load mid-stroke without live pressure. For applications requiring positive holding without continuous air supply, consider the SAIL locking variant. To match existing tooling, this cylinder shares standardized ISO 15552 dimensions, utilizing a G3/8 port, PT thread type, and compatible FA flange or LB foot mounts.
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 SAI63BX50 FAQ
