About the Airtac SAI63 Standard Cylinder SAI63X115S
The AirTAC SAI63X115-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 115 mm stroke provides a practical mid-range extension for general automation tasks. Because it utilizes an extruded aluminum barrel, it avoids tie-rod construction while maintaining strict ISO mounting dimensions.
This specific configuration includes a standard carbon steel piston rod and a built-in magnet (-S) for position sensing. The dual sensor grooves on the barrel directly accept CMSE or DMSE switches, ensuring reliable end-of-stroke feedback without requiring extra brackets.

Where the Airtac SAI63 Standard Cylinder SAI63X115S Is Used
Component Clamping
Provides reliable 1559 N clamping force at 0.5 MPa to secure medium-sized metal workpieces during CNC milling or drilling operations.
Package Diverting
Uses the 115 mm stroke to push packaged goods smoothly between adjacent conveyor lanes at high throughput speeds.
Gate Actuation
Drives lightweight safety guards and machine access gates, utilizing the integrated magnet for precise open and closed position feedback.
Is the Airtac SAI63 Standard Cylinder SAI63X115S the Right Cylinder?
If your application requires slightly less force, the 50 mm bore offers 982 N at 0.5 MPa; for heavier payloads, stepping up to the 80 mm bore provides 2513 N. The G3/8 PT tapered port matches the standard flow requirements for this bore size.
Keep in mind that the adjustable air cushions only decelerate the piston near the stroke ends; they do not lock the rod in place. If your machinery must hold a load securely during a complete loss of air pressure, integrate the SAIL pneumatic lock variant or an external pilot-operated check valve. For this 115 mm stroke, side-load bending is minimal, but standard rod-bearing lubrication should still be maintained.
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 SAI63X115S FAQ
At 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. If you increase the operating pressure to 0.7 MPa, the push force rises to 2182 N.
Yes, the SAI63X115-S is dimensionally interchangeable with other ISO 15552 profile cylinders. You can swap it directly into existing setups using standard FA, FB, LB, or TC mounting accessories without modifying the machine frame.
