About the Airtac SAI63 Standard Cylinder SAI63X160S
The AirTAC SAI63X160-S is a double-acting ISO 15552 profile cylinder engineered for standardized mounting interchangeability. It features a 63mm bore and a 160mm stroke, generating 1559 N of push force and 1402 N of pull force at 0.5 MPa. This stroke length is well-suited for medium-travel indexing and material handling tasks.
Configured with a standard carbon steel piston rod and a built-in magnet, this model operates seamlessly with CMSE and DMSE sensor switches housed in the dual-side extruded aluminum barrel grooves. Fluid supply connects via PT G3/8 tapered ports, while adjustable air cushions at both ends manage end-of-stroke impact.

Where the Airtac SAI63 Standard Cylinder SAI63X160S Is Used
Package Sorting Diverter
Uses the 160mm stroke to push parcels smoothly between adjacent conveyor lanes without overshooting the travel distance.
Component Clamping Fixture
Applies up to 1559 N of push force at 0.5 MPa to hold workpieces securely inside a CNC machining or assembly cell.
Pallet Stopper Gate
Acts as a reliable physical stop for pallets on a gravity roller track, utilizing the dual-side sensor grooves for position confirmation.
Is the Airtac SAI63 Standard Cylinder SAI63X160S the Right Cylinder?
Selecting this 63mm bore over the smaller 50mm variant provides a significant thrust upgrade, jumping from 982 N to 1559 N at 0.5 MPa. If your application requires less force, the 40mm bore offers 628 N, which may prevent unnecessary wear on smaller fixtures.
Because this is a standard double-acting cylinder, it cannot hold a load in place if air pressure drops or the valve is centered; the piston will drift. For vertical loads requiring fail-safe holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard 63mm bore, 160mm stroke, G3/8 port configuration with LB, FA, or TC mounting accessories.
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 SAI63X160S FAQ
At a standard operating pressure of 0.5 MPa, the SAI63X160-S 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 SAI63X160-S is a genuine ISO 15552 profile cylinder. Its mounting dimensions, 63mm bore, 160mm stroke, and G3/8 ports are dimensionally interchangeable with other ISO 15552 standard cylinders.
