About the Airtac SAI63 Standard Cylinder SAI63X165S
The AirTAC SAI63X165-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 165 mm stroke is well suited for mid-range automation tasks requiring robust linear motion. The extruded aluminum barrel omits tie-rods for a clean exterior.
This variant includes a magnetic piston (-S) that interfaces directly with CMSE and DMSE reed switches. The integrated sensor grooves on both sides of the barrel simplify position feedback mounting. A standard carbon steel piston rod provides durable performance, while adjustable air cushions at both ends manage impact deceleration.

Where the Airtac SAI63 Standard Cylinder SAI63X165S Is Used
Component Clamping
Secures heavy machined parts during secondary milling operations, utilizing the 1559 N push force to prevent workpiece shifting.
Pallet Diversion
Extends 165 mm to push product pallets off a main conveyor line into a secondary packaging station reliably.
Press Ejection
Cycles quickly to eject formed aluminum parts from a hydraulic press bed, using adjustable cushions to absorb end-of-stroke energy.
Is the Airtac SAI63 Standard Cylinder SAI63X165S the Right Cylinder?
Choose this 63 mm bore when an application requires stepping up from a 50 mm cylinder, which yields 982 N at 0.5 MPa, to gain significantly higher thrust. If your project demands even greater force, the 80 mm bore offers 2513 N at the same pressure. The 165 mm stroke provides ample extension without entering the long-stroke territory where side loading becomes a primary concern.
Because it is a double-acting cylinder, the SAI63X165-S relies on continuous air pressure to maintain its position. If pneumatic supply is lost, the rod will drift. For loads that must be held securely without live pressure, consider the SAIL locking variant or an external pilot-operated check valve. This model is dimensionally interchangeable per ISO 15552, accepting standard PT port threading and standard mounting accessories like FA flanges or TC trunnions.
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 SAI63X165S FAQ
At a standard operating pressure of 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes. The SAI63X165-S is built to the ISO 15552 dimensional standard, making it a direct replacement for other ISO 15552 profile cylinders. Ensure you match the PT port threading and mounting accessories.
