About the Airtac SAI63 Standard Cylinder SAI63AX115S
The AirTAC SAI63X115-S is a double-acting ISO 15552 profile cylinder with a 63mm bore and 115mm stroke. It delivers 1559N of push force and 1402N of pull force at 0.5 MPa, making it a robust choice for medium-duty automation. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration includes a -S magnet for use with CMSE and DMSE series sensor switches, which mount directly into the dual sensor grooves on both sides of the barrel. The piston rod is constructed from SUS420J2 stainless steel (material code A) for enhanced corrosion resistance, and it features PT (tapered) port threads with a G3/8 air supply connection.

Where the Airtac SAI63 Standard Cylinder SAI63AX115S Is Used
Automated Clamping
Provides 1559N of clamping force at 0.5 MPa, securely holding medium-sized metal workpieces for machining or welding operations.
Package Diverting
The 115mm stroke offers rapid actuation for sorting arms and diverter gates on high-speed packaging conveyor lines.
Material Lifting
Ideal for lifting and lowering lightweight pallets or sheet materials, utilizing the integrated -S magnet for end-of-stroke confirmation.
Is the Airtac SAI63 Standard Cylinder SAI63AX115S the Right Cylinder?
Select this 63mm bore model when a 50mm bore (982N push at 0.5 MPa) is insufficient for your load, but an 80mm bore (2513N push) would be physically oversized. The 115mm stroke provides a compact extension length for clamping, lifting, or pressing tasks. Because the SAI series is a true ISO 15552 profile cylinder, it serves as a direct drop-in replacement for any standard ISO 15552 unit sharing the same mounting interface and accessories.
If your application requires holding a load in place when air pressure is lost or exhausted, note that a standard SAI cylinder will drift. For positive position holding, you must specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder.
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.
