About the Airtac SAI63 Standard Cylinder SAI63X600
The AirTAC SAI63X600 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 600 mm stroke is well-suited for transferring products between conveyor zones or lifting mid-weight platforms. The extruded aluminum barrel design omits traditional tie-rods, providing a clean exterior that resists debris accumulation.
This actuator features a standard carbon steel piston rod for high tensile strength and utilizes a PT tapered port thread for reliable sealing. The barrel incorporates dual-sided sensor grooves ready for CMSE or DMSE switches, though adding the -S magnet option is required to enable magnetic sensing. For operations requiring end-position holding under pressure loss, consider the SAIL variant with its integrated air-released lock.

Where the Airtac SAI63 Standard Cylinder SAI63X600 Is Used
Pallet Transfer
Shifts heavy pallets smoothly between adjacent roller conveyors over a 600 mm gap without requiring multiple shorter actuators.
Component Indexing
Pushes automotive sub-assemblies into machining centers, utilizing the full stroke to clear safety light curtains.
Vertical Lift Gate
Elevates mezzanine access gates, providing 1559 N of lifting force at 0.5 MPa to overcome gravity and friction.
Is the Airtac SAI63 Standard Cylinder SAI63X600 the Right Cylinder?
If an application requires less force, stepping down to the 50 mm bore yields 982 N at 0.5 MPa, whereas moving up to an 80 mm bore provides 2513 N. At 600 mm of extension, the unsupported piston rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear and cylinder failure, pair this unit with an external guide rail or select a guided cylinder module.
This model serves as a direct dimensional drop-in replacement for any ISO 15552 cylinder, matching the 63 mm bore, 600 mm stroke, G3/8 port, and standard mounting accessories like FA flanges or TC trunnions. Note that standard double-acting cylinders drift when air pressure is removed; use an external rod lock for safety if gravity loads are present.
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 SAI63X600 FAQ
At 0.5 MPa operating pressure, the SAI63X600 generates 1559 N of push force and 1402 N of pull force. If pressure is increased to 0.7 MPa, the push force reaches 2182 N.
Yes. The SAI63X600 is built to the ISO 15552 standard, making its mounting dimensions and G3/8 port fully interchangeable with other ISO 15552 profile cylinders like those from Festo or SMC.
