About the Airtac SAI63 Standard Cylinder SAI63X140S
The AirTAC SAI63X140-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 140 mm stroke provides ample extension for mid-range automation tasks. The extruded aluminum barrel design omits tie rods, ensuring a clean exterior while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
Equipped with a magnetic piston (-S), this variant is fully compatible with CMSE and DMSE series reed switches for precise end-of-stroke positioning. The standard carbon steel piston rod offers robust durability for industrial environments, while adjustable air cushions at both ends ensure smooth deceleration across its 30-800 mm/s operating speed range.

Where the Airtac SAI63 Standard Cylinder SAI63X140S Is Used
Mid-Force Clamping
Provides 1559 N of clamping thrust at 0.5 MPa, securely holding heavy metal workpieces during machining or welding operations.
Package Diverting
The 140 mm stroke extends rapidly across a conveyor belt to redirect medium-sized cartons into sorting lanes.
Parts Ejection
Uses the 140 mm stroke to push stamped metal components out of a press bed, utilizing the magnetic piston for position confirmation.
Is the Airtac SAI63 Standard Cylinder SAI63X140S the Right Cylinder?
Selecting this 63 mm bore is ideal when a 50 mm bore (providing 982 N push at 0.5 MPa) lacks the necessary thrust, but an 80 mm bore (2513 N push) would be physically oversized. The 140 mm stroke offers a balanced reach for standard pick-and-place or clamping duties. Because this is a 140 mm stroke, side-load stress on the rod bearing is minimal compared to longer extensions, though external guides are always recommended if heavy off-center loads are attached.
For any application requiring the load to be held securely in place during a complete loss of air pressure, note that the standard adjustable air cushion only decelerates the piston at stroke end and does not act as a brake. In such drop-prevention scenarios, specify the SAIL (pneumatic lock) or BSAI (clamp-lock) variant instead. To replace an existing ISO 15552 cylinder, match the 63 mm bore, 140 mm stroke, PT G3/8 port, and choose appropriate 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 SAI63X140S FAQ
