About the Airtac SAI63 Standard Cylinder SAI63X155S
The AirTAC SAI63X155-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 155 mm stroke provides the exact mid-range extension needed for automated clamping and lifting tasks. The extruded aluminum barrel design omits tie-rods, ensuring a clean exterior that resists debris accumulation.
Equipped with a magnetic piston (-S), this unit supports direct mounting of CMSE or DMSE sensor switches along the dual side grooves. The standard carbon steel piston rod offers robust durability for general industrial pneumatics, while the adjustable air cushions at both ends absorb end-of-stroke impact to extend operational lifespan.

Where the Airtac SAI63 Standard Cylinder SAI63X155S Is Used
Automated Clamping
Provides 1559 N of secure clamping force at 0.5 MPa for holding heavy metal workpieces during CNC machining or welding operations.
Package Diverting
Uses the 155 mm stroke to push heavy cartons or totes between adjacent conveyor lanes in high-speed distribution centers.
Material Lifting
Lifts and lowers pneumatic stop gates or small platform actuators where a reliable 63 mm bore double-acting motion is required.
Is the Airtac SAI63 Standard Cylinder SAI63X155S the Right Cylinder?
Selecting this 63 mm bore over the smaller 50 mm variant upgrades your thrust from 982 N to 1559 N at 0.5 MPa, making it suitable for heavier payloads. Conversely, if your application only requires 982 N, stepping down to the 50 mm bore saves physical envelope space. Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal, though standard alignment practices should still be observed.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement for other standard profile cylinders with matching 63 mm bore, 155 mm stroke, PT G3/8 ports, and standard mounting accessories like LB foot or TC trunnion brackets. Note that the adjustable cushions decelerate the piston but do not lock the load; if pressure is lost, the rod will drift. For dead-load holding, consider 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 SAI63X155S FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X155-S is dimensionally interchangeable per ISO 15552 standards. It shares the same 63 mm bore, 155 mm stroke, G3/8 port, and mounting interface dimensions as comparable ISO 15552 profile cylinders from other manufacturers.
