The AirTAC Airtac SAI63 Standard Cylinder SAI63BX500S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø63mm bore and 500mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI63X500-S is a double-acting ISO 15552 profile cylinder engineered for rigorous duty cycles. It provides a robust push force of 1559 N at 0.5 MPa and 2182 N at 0.7 MPa, making it a strong choice for mid-weight manipulation. The 500 mm stroke delivers ample extension for automated routing and indexing tasks.
Built to exact ISO 15552 mounting dimensions, this unit serves as a direct replacement for comparable profile cylinders. It features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for seamless operation with CMSE or DMSE reed switches via the dual side sensor grooves. PT tapered ports ensure a positive, leak-free pneumatic connection.

Drives long-travel linear actuators in CNC material routing and woodworking machinery where a 500 mm extension is required to clear the work envelope.
Executes 500 mm transfer strokes to push heavy pallets or totes from conveyor lines into downstream wrapping stations.
Provides reliable 1559 N push force at 0.5 MPa to eject molded components from mid-sized fabrication presses.
If your application demands less push energy, stepping down to a 50 mm bore yields 982 N at 0.5 MPa, whereas upgrading to an 80 mm bore provides 2513 N. Because this 500 mm stroke generates significant rod extension, side loads can severely stress the rod bearing and cause premature wear. Always utilize an external guide rail or a dedicated guided cylinder to absorb lateral forces and prevent rod bending.
This model uses a G3/8 port, an M16x1.5 rod thread, and a 36 mm cushion length. Note that the standard adjustable air cushions only decelerate the piston near stroke ends; they will not hold a load if air pressure drops. For position holding without live pressure, select the SAIL (air-released lock) or BSAI (clamp-lock) variant.
Quick checklist
At an operating pressure of 0.5 MPa, this 63 mm bore cylinder generates a push force of 1559 N, increasing to 2182 N at 0.7 MPa.
Yes, the SAI series is dimensionally interchangeable per ISO 15552, allowing it to serve as a direct replacement for other ISO 15552 profile cylinders using standard FA, FB, or TC mounting accessories.
