About the Airtac SAI63 Standard Cylinder SAI63BX5
The AirTAC SAI63X5 is a double-acting ISO 15552 profile cylinder engineered for ultra-short stroke applications. It delivers a robust push force of 1559 N at 0.5 MPa, making it highly effective for compact pressing and clamping tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that easily drops into standardized ISO 15552 mounting footprints.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in harsh environments. It utilizes PT tapered port threads and lacks a standard magnet. If your application requires end-of-stroke sensing, you must specify the -S magnet option to utilize CMSE or DMSE switches in the dual sensor grooves.

Where the Airtac SAI63 Standard Cylinder SAI63BX5 Is Used
Short-Stroke Clamping
Ideal for holding heavy workpieces firmly in place during machining operations using its 1559 N push force.
Compact Pressing
Executes high-force pressing and riveting tasks in tight spaces where a 5mm stroke is sufficient for the operation.
Ejector Mechanisms
Provides a quick, powerful 5mm ejection punch to dislodge finished parts from automated fixtures.
Is the Airtac SAI63 Standard Cylinder SAI63BX5 the Right Cylinder?
Selecting this 5mm stroke is ideal when you need maximum thrust in a minimal footprint, but be aware that the extremely short travel limits its use to contact operations rather than material transfer. If you need to secure a load mechanically without constant air pressure, the standard SAI will drift; you should evaluate the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock for fail-safe holding. For interchangeability, match the 63mm bore, 5mm stroke, G3/8 PT port, and your required mounting accessory.
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.
