About the Airtac SAI63 Standard Cylinder SAI63X170
The AirTAC SAI63X170 is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 1559 N of push force at 0.5 MPa. Its 170 mm stroke provides the precise mid-range extension needed for general automation tasks. The extruded aluminum barrel design omits tie-rods, ensuring a clean exterior that resists debris accumulation.
This unit features a standard carbon steel piston rod and PT tapered port threads. For environments requiring position feedback, the barrel includes integrated sensor grooves on both sides, allowing you to easily mount CMSE or DMSE switches by specifying the -S magnet option.

Where the Airtac SAI63 Standard Cylinder SAI63X170 Is Used
Component Clamping
Provides secure 1559 N holding force at 0.5 MPa for fixturing metal parts during machining or welding processes.
Package Diverting
Uses the 170 mm stroke to push cartons smoothly between adjacent conveyor lanes in material handling lines.
Pneumatic Pressing
Drives small assembly presses for inserting bearings or pins with controlled, repeatable force.
Is the Airtac SAI63 Standard Cylinder SAI63X170 the Right Cylinder?
Selecting this bore size makes sense when your application requires more power than a 50 mm cylinder (982 N push at 0.5 MPa) but does not demand the full 2513 N output of an 80 mm unit. The 170 mm stroke offers ample travel for indexing and lifting without the space constraints of longer strokes.
If your machinery loses air pressure, this standard cylinder cannot hold its load and will drift. For suspended or vertical loads that require fail-safe positioning without live pressure, consider the SAIL variant with an air-released lock or the BSAI clamp-lock series. This model is dimensionally interchangeable per ISO 15552, matching bore, stroke, G3/8 port, and standard mounting accessories like FA flanges or TC trunnions.
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 SAI63X170 FAQ
At a 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 SAI63X170 is built to the ISO 15552 profile standard, making its mounting dimensions, 63 mm bore, 170 mm stroke, and G3/8 port fully interchangeable with other ISO 15552 cylinders.
