About the Airtac SAI63 Standard Cylinder SAI63AX290
The AirTAC SAI63X290 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 290mm stroke. It generates a push force of 1559 N at 0.5 MPa, extending to 2182 N at 0.7 MPa, making it a robust choice for medium-duty automation. This 290mm stroke length is well-suited for traversing wider machine frames or moving pallets.
This specific configuration includes a SUS420J2 stainless steel piston rod (option A) for superior corrosion resistance in humid environments. It uses PT tapered port threads and lacks a standard magnet, meaning position detection via CMSE or DMSE sensors is not supported without modification. The extruded aluminum barrel incorporates sensor grooves on both sides for straightforward accessory mounting.

Where the Airtac SAI63 Standard Cylinder SAI63AX290 Is Used
Pallet Handling
Provides the 1559 N push force needed to index heavy pallets along a 290mm transfer distance.
Clamping Fixtures
Secures workpieces during machining operations, utilizing its SUS420J2 stainless rod to resist coolant spray.
Material Diverters
Actuates sorting gates on packaging lines where a longer 290mm reach is required to clear the conveyor.
Is the Airtac SAI63 Standard Cylinder SAI63AX290 the Right Cylinder?
Choose this 63mm bore when a 50mm bore's 982 N at 0.5 MPa is insufficient, but avoid stepping up to an 80mm bore (2513 N at 0.5 MPa) unless your application strictly demands the extra thrust. At a 290mm stroke, the unsupported piston rod is susceptible to bending under lateral loads; utilize an external guide rail or a guided cylinder to prevent premature rod-bearing wear.
This model provides a true ISO 15552 mounting interface, ensuring dimensional interchangeability with other standard profile cylinders. To match this unit, specify a 63mm bore, 290mm stroke, PT G3/8 port, and compatible mounting accessories like an FA flange or TC trunnion. Note that a standard SAI cylinder will drift if air pressure is lost; for position 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.
