About the Airtac SAI63 Standard Cylinder SAI63BX175S
The AirTAC SAI63X175-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force and 1402 N of pull force at 0.5 MPa. Its 175 mm stroke provides the precise mid-range extension needed for automated clamping and material handling tasks. Built to the exacting ISO 15552 mounting interface, this extruded aluminum barrel cylinder serves as a direct replacement for other standard profile cylinders.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance in humid or washdown environments. It features PT tapered port threads and is equipped with a magnet (-S) for seamless integration with CMSE or DMSE position sensors along the dual barrel grooves. Adjustable air cushions at both ends ensure smooth deceleration of the 30-800 mm/s piston speed.

Where the Airtac SAI63 Standard Cylinder SAI63BX175S Is Used
Automated Clamping Stations
Provides 1559 N of secure clamping force at 0.5 MPa for holding aluminum or steel castings during CNC machining operations.
Package Diverting
Uses the 175 mm stroke to push heavy cartons from a main conveyor line to a secondary packaging lane with reliable speed.
Press Ejection Systems
Retracts with 1402 N of pull force to extract finished stamped parts from tight dies, utilizing the SUS304 rod for durability.
Is the Airtac SAI63 Standard Cylinder SAI63BX175S the Right Cylinder?
Selecting this 63 mm bore over the smaller 50 mm variant doubles your thrust from 982 N to 1559 N at 0.5 MPa, while stepping up to the 80 mm bore yields 2513 N if your application demands moving substantially heavier payloads. The 175 mm stroke hits a sweet spot for compact machinery, though any design exceeding 300 mm of extension should incorporate external guides to prevent rod-bearing bending under side loads.
Because it is a double-acting cylinder, the SAI63X175-S relies on continuous air pressure to maintain its position. If air is exhausted or the valve is centered, the piston will drift. For applications requiring static load holding without live pressure, specify the SAIL locking variant or integrate an external pilot-operated check valve. This model uses G3/8 ports, accepts standard ISO 15552 mounting accessories like FA flanges or TC trunnions, and requires the -S magnet for sensor functionality.
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 SAI63BX175S FAQ
Operating at 0.5 MPa, this 63 mm bore cylinder generates a push force of 1559 N and a pull force of 1402 N. If pressure is increased to 0.7 MPa, the push force rises to 2182 N.
