About the Airtac SAI100 Standard Air Cylinder SAI100BX650
The AirTAC SAI100X650 is a double-acting ISO 15552 profile cylinder engineered to deliver 5497 N of push force at 0.7 MPa. With a 100mm bore and 650mm stroke, this extruded aluminum barrel unit is designed for heavy-duty automation requiring substantial travel. The PT tapered port threads ensure a robust, leak-free pneumatic connection in demanding industrial environments.
This specific configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in humid or chemically exposed settings. Because no magnet is specified, it operates without sensor detection out of the box. The standardized ISO 15552 mounting dimensions make it a seamless drop-in replacement for comparable profile cylinders.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX650 Is Used
Automotive Body Welding
Drives large welding fixtures and handling arms where the SUS304 rod resists weld spatter and shop floor humidity over the 650mm travel.
Heavy Stamping Ejection
Provides the 3927 N of push force at 0.5 MPa needed to eject heavy stamped metal parts from large progressive dies.
Pallet Lift Stations
Lifts loaded pallets in high-throughput material handling lines, utilizing the ISO 15552 interface for easy maintenance swaps.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX650 the Right Cylinder?
At 650 mm of travel, the unsupported piston rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear and seal failure, pair this cylinder with an external linear guide or use a fully guided cylinder design. If your application requires less force, stepping down to an 80mm bore yields 3518 N at 0.7 MPa; if you need more power, a 125mm bore provides 8590 N.
This standard double-acting cylinder relies on air pressure for movement and will drift if pressure is lost or the valve centers. The adjustable air cushions at both ends only decelerate the piston near stroke end to prevent impact damage; they do not hold the load. For true position holding without live pressure, consider the SAIL lock or BSAI clamp-lock variants. The ISO 15552 interface ensures dimensional interchangeability with standard foot (LB), flange (FA/FB), and trunnion (TC) mounts.
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 SAI100 Standard Air Cylinder SAI100BX650 FAQ
The SAI100X650 generates 3927 N of push force and 3681 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X650 is dimensionally interchangeable per ISO 15552. You can use it as a drop-in replacement for other standard profile cylinders with the same 100mm bore and 650mm stroke, utilizing its G1/2 PT ports.
