About the Airtac SAI63 Standard Cylinder SAI63X150S
The AirTAC SAI63X150-S is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 1559 N and a pull force of 1402 N at 0.5 MPa. The 150 mm stroke provides an optimal mid-range extension for general automation tasks. Built with a standardized mounting interface, it serves as a direct replacement for other ISO 15552 cylinders.
This specific configuration includes a magnetic piston (-S) for use with CMSE and DMSE position sensors, which seat directly into the dual sensor grooves on the extruded aluminum barrel. The piston rod utilizes a standard carbon steel construction, and the PT tapered port threads ensure a secure, leak-free pneumatic connection.

Where the Airtac SAI63 Standard Cylinder SAI63X150S Is Used
Clamping Mechanisms
Provides the 1559 N force required to secure heavy metal castings during CNC machining operations.
Package Diverting
Drives robust pusher arms at intermediate conveyor lanes to redirect heavy cartons efficiently.
Material Pressing
Applies consistent downward pressure for assembling bearings into housings on automated lines.
Is the Airtac SAI63 Standard Cylinder SAI63X150S the Right Cylinder?
Select this 63 mm bore when an application requires stepping up from a 50 mm cylinder (which offers 982 N push at 0.5 MPa) to handle heavier payloads without the bulk of an 80 mm unit. To match an existing ISO 15552 footprint, verify the 150 mm stroke, G3/8 port, and mounting accessory type (such as LB foot or TC trunnion). Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal, though external guides remain best practice for rigid loads. If the machinery loses air pressure, this standard cylinder cannot hold its load; integrate the SAIL variant for pneumatic locking or utilize an external pilot-operated check valve.
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 SAI63X150S FAQ
At 0.5 MPa operating pressure, this cylinder generates 1559 N of push force and 1402 N of pull force. If pressure increases to 0.7 MPa, the push force rises to 2182 N.
Yes, the SAI63X150-S is dimensionally interchangeable per ISO 15552. You can swap it directly into existing mounts designed for other ISO 15552 profile cylinders, provided the port and stroke match.
