Airtac SAI63 Standard Cylinder SAI63AX1000
The AirTAC Airtac SAI63 Standard Cylinder SAI63AX1000 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø63mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAI63 Standard Cylinder SAI63AX1000
The AirTAC SAI63X1000 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 1000mm stroke. Because this stroke exceeds the standard 1500mm maximum for this bore, it is manufactured as a made-to-order non-standard stroke unit. It generates a push force of 1559 N and a pull force of 1402 N at 0.5 MPa.
This specific configuration features a SUS420J2 stainless steel piston rod (option A) for enhanced corrosion resistance. It utilizes PT tapered port threads (G3/8) and lacks a standard magnet, meaning it is not sensor-ready out of the box.

Where the Airtac SAI63 Standard Cylinder SAI63AX1000 Is Used
Long-Stroke Ejection
Ideal for pushing parts out of molds or press beds over a 1000mm distance where a 1559 N push force at 0.5 MPa is sufficient.
Material Transfer
Moves workpieces between separated processing stations, utilizing the 63mm bore's 2182 N force at 0.7 MPa to overcome friction.
Sorting Diversion
Actuates long-travel sorting gates on conveyor lines, relying on external guides to support the extended 1-meter rod.
Is the Airtac SAI63 Standard Cylinder SAI63AX1000 the Right Cylinder?
When sizing this bore, stepping down to a 50mm cylinder reduces the 0.5 MPa push force to 982 N, while stepping up to an 80mm bore increases it to 2513 N. Because the 1000mm stroke creates a long unsupported rod, you must manage side load carefully to prevent rod-bearing bending; using an external guide rail or a dedicated guided cylinder is strongly recommended.
As a true ISO 15552 profile barrel cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders. It uses a G3/8 PT port, an M16x1.5 rod thread, and 36mm adjustable air cushions at both ends. If your application requires position holding without live air pressure, select the SAIL (air-released lock) or BSAI (clamp-lock) variant instead of relying on the standard cushion.
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 SAI63AX1000 FAQ
At 0.5 MPa, the SAI63X1000 provides a push force of 1559 N and a pull force of 1402 N. At 0.7 MPa, the push force increases to 2182 N.
Yes, it is a profile-barrel ISO 15552 cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders. Note that the 1000mm stroke is a non-standard made-to-order length for this 63mm bore.
