About the Airtac SAI63 Standard Cylinder SAI63X175CA
The AirTAC SAI63X175 is a double-acting ISO 15552 profile cylinder offering a push force of 1559 N at 0.5 MPa. Its 175 mm stroke is well-suited for medium-travel automation tasks requiring reliable linear motion. The extruded aluminum barrel design omits tie rods, providing a clean exterior while maintaining robust structural integrity.
This unit ships with a standard carbon steel piston rod and PT tapered port threads. For applications needing position feedback, the barrel features dual-sided sensor grooves compatible with CMSE and DMSE switches when a magnet is specified. If your assembly requires dual-end rod extension, the related SAID type offers a mirrored piston rod configuration.

Where the Airtac SAI63 Standard Cylinder SAI63X175CA Is Used
Automated Clamping
Provides secure holding force for machining fixtures, utilizing its 1559 N push capacity to stabilize metal components during milling or drilling operations.
Package Diversion
Actuates routing gates on packaging lines, where the 175 mm stroke offers sufficient travel to redirect parcels smoothly between conveyor belts.
Material Lifters
Drives vertical lifting platforms for heavy components, taking advantage of the ISO 15552 mounting interface for rigid frame integration.
Is the Airtac SAI63 Standard Cylinder SAI63X175CA the Right Cylinder?
Selecting this 63 mm bore makes sense when the 50 mm class (982 N at 0.5 MPa) is insufficient, but the larger 80 mm option (2513 N at 0.5 MPa) would be overkill. The 175 mm stroke provides ample travel for standard manipulators. For this specific configuration, the CA clevis mounting accessory allows pivoting movement, and the PT port ensures a tight pneumatic seal.
Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal compared to longer variants. However, remember that standard air cushions only decelerate the piston near the end caps; they do not lock the load. If your mechanism must hold position during a loss of air pressure, consider integrating the SAIL variant with an air-released lock or an external rod lock.
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 SAI63X175CA FAQ
