About the Airtac SAI63 Standard Cylinder SAI63BX600S
The AirTAC SAI63X600-S is a double-acting ISO 15552 profile cylinder engineered for demanding automation environments. Operating at 0.15-1.0 MPa, it generates 1559 N of thrust and 1402 N of pull force at 0.5 MPa. The generous 600 mm stroke makes it highly suitable for material transfer and large-format packaging machinery. This specific configuration includes a SUS304 stainless steel rod (material code B) for superior corrosion resistance in harsh or washdown settings.
Equipped with a built-in magnet (-S), this model seamlessly integrates with CMSE and DMSE sensor switches housed in the dual-side grooves of the extruded aluminum barrel. It features PT tapered port threads and adjustable air cushions at both ends to dampen impact at high cycling speeds. As a genuine AirTAC component, it guarantees true dimensional interchangeability with any ISO 15552 standard cylinder.

Where the Airtac SAI63 Standard Cylinder SAI63BX600S Is Used
Long-Stroke Transfer
Ideal for pushing heavy pallets between adjacent conveyor lines where a 600 mm extension is required to clear safety guarding.
Large Door Manipulation
Provides the 1559 N force needed to actuate heavy industrial machine enclosure doors or safety chutes over a wide opening distance.
Washdown Handling
The SUS304 stainless steel rod excels in food processing or chemical environments where moisture and corrosive cleaners would degrade standard carbon steel.
Is the Airtac SAI63 Standard Cylinder SAI63BX600S the Right Cylinder?
Choose this 63 mm bore when 50 mm (982 N push at 0.5 MPa) is insufficient but 80 mm (2513 N) would overcomplicate your envelope and air consumption. The 600 mm stroke operates at speeds of 30-800 mm/s. Because the extended 600 mm rod is highly susceptible to bending under side loads, utilizing an external guide rail or a fully guided cylinder is strongly recommended to prevent premature rod-bearing wear.
If your mechanism must hold a load vertically or resist drifting when air pressure is removed or a valve centers, the standard air cushion will not act as a brake. For fail-safe position holding, specify the SAIL (air-released lock) variant or select the BSAI bidirectional clamp-lock cylinder. For a direct ISO 15552 replacement, match the 63 mm bore, 600 mm stroke, G3/8 PT ports, and ensure your mounting accessory (such as an LB foot or TC trunnion) accommodates the profile barrel.
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 SAI63BX600S FAQ
At 0.5 MPa, it provides 1559 N of push force and 1402 N of pull force. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 318 kgf.
Yes, the SAI series is dimensionally interchangeable per ISO 15552. You can use it as a direct replacement for other ISO 15552 profile cylinders by matching the 63 mm bore, 600 mm stroke, and G3/8 port size.
