About the Airtac SAI63 Standard Cylinder SAI63BX190S
The AirTAC SAI63X190-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 190mm stroke. It delivers a robust push force of 1559 N at 0.5 MPa, making it highly suitable for medium-duty industrial handling tasks. Because this specific 190mm stroke falls outside the standard increments, it is manufactured as a made-to-order unit to fit precise machinery spacing requirements.
This variant includes a built-in magnet (-S) for seamless integration with CMSE and DMSE reed or solid-state sensors along the extruded aluminum barrel. Furthermore, it is configured with a SUS304 stainless steel piston rod (option B) for superior corrosion resistance, and utilizes PT tapered port threads to ensure a rigid, leak-free pneumatic connection.

Where the Airtac SAI63 Standard Cylinder SAI63BX190S Is Used
Material Diversion
Ideal for driving diverter arms on packaging lines where the 1559 N force at 0.5 MPa easily pushes cartons between adjacent belts.
Press Fit Operations
Provides consistent downward pressure for assembling small bushings or pins into aluminum housings without damaging surrounding components.
Gate Control
Actuates process flow gates in bulk material handling systems, utilizing the 190mm stroke to fully open and close discharge hoppers.
Is the Airtac SAI63 Standard Cylinder SAI63BX190S the Right Cylinder?
When sizing this actuator, consider stepping down to a 50mm bore if your load requires only 982 N of push force at 0.5 MPa, which saves valuable space and compressed air. Conversely, if you need to shift heavier jigs, the 80mm bore provides 2513 N at the same pressure. Because the stroke is 190mm, mounting accessories like the FA flange or LB foot bracket must be aligned precisely to prevent rod-bearing side load wear. To achieve true ISO 15552 interchangeability, match the 63mm bore, 190mm stroke, G3/8 port, and ensure your mounting hardware and magnet option are correctly specified.
Remember that the standard SAI does not secure a load when air pressure is removed; the piston will drift if the air supply is exhausted or a valve is centered. If your machinery requires fail-safe position holding, you should evaluate the SAIL variant with its pneumatic lock or the BSAI bidirectional clamp-lock cylinder.
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 SAI63BX190S FAQ
