About the Airtac SAI63 Standard Cylinder SAI63X115
The AirTAC SAI63X115 is a double-acting ISO 15552 profile cylinder offering 1559 N of push force at 0.5 MPa. Its 115 mm stroke is well suited for mid-length actuation tasks in automated machinery. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that simplifies integration into tight spaces.
This specific configuration features a standard carbon steel piston rod and PT tapered port threads. Because a magnet is not specified, it is set up for standard pneumatic operation without integrated sensor detection. For applications requiring high temperature resistance up to the upper limits, Viton (H) seals can be substituted for the standard TPU elastomers.

Where the Airtac SAI63 Standard Cylinder SAI63X115 Is Used
Automated Assembly
Drives mid-stroke clamping and pressing actions with 1559 N of push force at 0.5 MPa.
Material Handling
Actuators divert or stop packages on conveyor lines using a 115 mm stroke.
Packaging Equipment
Provides reliable linear motion for sealing and folding packaging flaps.
Is the Airtac SAI63 Standard Cylinder SAI63X115 the Right Cylinder?
If 1559 N at 0.5 MPa is insufficient for your load, consider stepping up to the 80 mm bore, which provides 2513 N of push force. Conversely, if your application requires less force, the 50 mm bore yields 982 N.
As a genuine ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke. Ensure your setup uses a G3/8 port and matches the standard mounting accessories like FA flanges or TC trunnions. Note that the adjustable air cushions only decelerate the piston near the stroke ends; they do not hold a load. If position holding without air pressure is required, explore the SAIL variant with an air-released 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.
