About the Airtac SAI63 Standard Cylinder SAI63X600SN
The AirTAC SAI63X600-S is a double-acting ISO 15552 profile cylinder engineered for long-stroke automation. It provides a push force of 1559 N and a pull force of 1402 N at 0.5 MPa, making it suitable for moving substantial loads over its 600 mm travel. The extruded aluminum barrel design omits tie-rods, offering a clean exterior that drops directly into standard ISO 15552 mounting interfaces.
This specific configuration includes a magnetic piston (-S) for position detection via CMSE or DMSE switches, which seat neatly into the dual sensor grooves on the barrel. It is built with a standard carbon steel piston rod and NBR seals, optimizing it for reliable operation in typical industrial temperatures. Operating speed ranges from 30-800 mm/s, adjustable via end-of-stroke air cushions.

Where the Airtac SAI63 Standard Cylinder SAI63X600SN Is Used
Long-Stroke Material Transfer
Pushes heavy pallets or workpieces across a 600 mm gap on a production line, utilizing the 1559 N force at 0.5 MPa to overcome friction.
Vertical Lift Gates
Actuates lightweight safety gates or material diversion flaps. Note that an external lock is required if the load must be held during an emergency shutdown.
Large Component Indexing
Shifts automotive or heavy machinery components into machining stations, relying on the adjustable air cushions to decelerate the mass smoothly at stroke end.
Is the Airtac SAI63 Standard Cylinder SAI63X600SN the Right Cylinder?
Selecting this 63 mm bore over the smaller 50 mm variant increases your 0.5 MPa push force from 982 N to 1559 N, providing a significant uplift in work output without a massive footprint jump. Conversely, if your application requires less than 1000 N, stepping down to the 50 mm bore saves space and air consumption. The 600 mm stroke classifies this as a long-stroke application, meaning the unsupported rod is susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external linear guide or use a guided cylinder carriage.
Because it is a standard double-acting cylinder, it cannot hold a load in place if air pressure is lost or the control valve is centered; the piston will drift. For gravity-loaded vertical applications requiring safety locking upon pressure loss, consider the SAIL variant with an air-released lock. This SAI63X600-S uses a G3/8 PT tapered port and supports standard ISO 15552 mounting accessories like FA flanges or TC trunnions.
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 SAI63X600SN FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides a push force of 1559 N and a pull force of 1402 N. If pressure is increased to 0.7 MPa, the push force rises to 2182 N.
Yes, the SAI63X600-S is dimensionally interchangeable per ISO 15552. You can drop it into existing ISO 15552 mounting footprints, matching the G3/8 port and standard trunnion or flange accessories.
