About the Airtac SAI63 Standard Cylinder SAI63AX450S
The AirTAC SAI63X450-S is a double-acting profile cylinder built to ISO 15552 dimensional standards, ensuring drop-in compatibility with other standard interface setups. It delivers a pushing force of 1559 N and a pulling force of 1402 N at 0.5 MPa, making it well-suited for moderate linear actuation over its 450 mm travel distance. The extruded aluminum barrel design omits tie-rods for a cleaner exterior.
This specific configuration includes a magnetic piston for use with CMSE and DMSE series reed switches, enabling precise end-of-stroke detection. The piston rod is constructed from SUS420J2 stainless steel (option A) for enhanced corrosion resistance. Fluid connections utilize PT tapered threads, and the cylinder features adjustable air cushions at both ends to manage impact forces at the stroke limits.

Where the Airtac SAI63 Standard Cylinder SAI63AX450S Is Used
Material Handling
Ideal for pushing or diverting packages on a conveyor line over a 450 mm distance, utilizing the 1559 N force to move standard weighted goods reliably.
Automated Clamping
Provides secure holding force for machining or assembly processes, where the SUS420J2 stainless steel rod offers resistance against coolant splashes.
Vertical Lifting
Suitable for elevating lightweight pneumatic lift gates or pallet stops, taking advantage of the magnetic piston for precise upper and lower limit signaling.
Is the Airtac SAI63 Standard Cylinder SAI63AX450S the Right Cylinder?
Selecting this 63 mm bore is ideal when an application requires around 1559 N of push force at 0.5 MPa. If your project needs less force, stepping down to a 50 mm bore yields 982 N; if more force is required, moving up to an 80 mm bore provides 2513 N. Because this model features a 450 mm stroke, it is critical to manage side loads. Long unsupported rods are prone to bending under lateral forces, so utilizing an external guide rail or a fully guided cylinder mechanism is strongly recommended to prevent premature rod-bearing wear.
For drop-in replacements, verify the ISO 15552 mounting interface, the 450 mm stroke, the G3/8 port size, and the required mounting accessory (such as an LB foot or TC trunnion). Note that a standard double-acting cylinder will drift if air pressure is lost. If your application must hold a load safely during an air failure, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-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.
Airtac SAI63 Standard Cylinder SAI63AX450S FAQ
At an operating pressure of 0.5 MPa, this 63 mm bore cylinder generates 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, the SAI63X450-S is dimensionally interchangeable per ISO 15552 standards. Ensure you match the G3/8 port, 450 mm stroke, and mounting accessories like the FA flange or CB clevis for a seamless drop-in replacement.
