About the Airtac SAI63 Standard Cylinder SAI63X95S
The AirTAC SAI63X95-S is a double-acting ISO 15552 profile cylinder offering a 63mm bore and 95mm stroke. It generates 1559 N of push force at 0.5 MPa, making it well-suited for mid-range industrial actuation. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops directly into existing ISO 15552 mounting interfaces.
Configured with a magnetic piston, this unit is fully compatible with CMSE and DMSE series sensors. The standard carbon steel piston rod handles demanding cycles, while the adjustable air cushions at both ends manage end-of-stroke kinetic energy. A 95 mm stroke is optimal for compact clamping and short-indexing tasks.

Where the Airtac SAI63 Standard Cylinder SAI63X95S Is Used
Mid-Tonnage Clamping
Provides 1559 N of push force at 0.5 MPa to secure heavy metal workpieces during machining operations.
Package Diverting
The 95mm stroke offers rapid extension and retraction to push products across high-speed sorting belts.
Gate Control
Actuates medium-sized process gates and machine safety doors, utilizing the magnetic piston for closed-limit confirmation.
Is the Airtac SAI63 Standard Cylinder SAI63X95S the Right Cylinder?
Choose this 63mm bore when a 50mm bore falls short of the required thrust (982 N at 0.5 MPa) but you want to avoid the larger 80mm footprint (2513 N at 0.5 MPa). To match an existing ISO 15552 cylinder, verify the 95mm stroke, G3/8 PT port, and required mounting accessory (such as an FA flange or LB foot). Remember to include the -S magnet if your application relies on CMSE or DMSE position sensing.
Because the stroke is under 300mm, rod-bearing bending from side loads is less severe than in long-stroke setups. However, if the load cannot hold its position safely upon air pressure loss, do not rely on the air cushion as a brake; instead, integrate an external pilot-operated check valve or select 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.
Airtac SAI63 Standard Cylinder SAI63X95S FAQ
At 0.5 MPa, this 63mm bore cylinder provides a push force of 1559 N and a pull force of 1402 N. At 0.9 MPa, the push force increases to 2805 N.
Yes. The SAI series is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing mounting footprints, but verify your G3/8 port thread and mounting accessory dimensions before installation.
