About the Airtac SAI100 Standard Air Cylinder SAI100AX650S
The AirTAC SAI100X650-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Operating at 0.7 MPa, it generates 5497 N of push force and 3681 N of pull force, making it well-suited for high-impact pressing and heavy load manipulation. The 650 mm stroke provides extensive linear travel for automated machinery.
This configuration includes a SUS420J2 stainless steel rod (material code A) for superior corrosion and scratch resistance in harsh environments. It utilizes PT tapered port threads and features a magnetic piston (-S) designed to interface seamlessly with CMSE and DMSE reed switches via the dual-side sensor grooves on the extruded aluminum barrel.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX650S Is Used
Heavy-Duty Pressing
Ideal for stamping and forming operations requiring substantial force, leveraging its 5497 N push capability at 0.7 MPa.
Bulk Material Diversion
The 650 mm stroke provides the extended reach needed to actuate large diverter arms on heavy-duty packaging and sorting conveyors.
Automated Assembly Lifts
Provides robust vertical actuation for lifting heavy pallets or chassis subcomponents, utilizing its magnetic piston for precise end-position sensing.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX650S the Right Cylinder?
Select this 100 mm bore when a 80 mm bore is insufficient, as the 80 mm yields only 3518 N at 0.7 MPa. For applications requiring less force and faster cycling, stepping down to a 63 mm bore (2182 N at 0.7 MPa) is recommended. At 650 mm of stroke, the unsupported piston rod is highly susceptible to bending under side loads; utilizing an external linear guide or a guided cylinder is essential to prevent premature rod-bearing wear.
As a true ISO 15552 profile cylinder, it offers drop-in dimensional interchangeability with other standard cylinders. Replacement matching requires a 100 mm bore, 650 mm stroke, G1/2 port, and an appropriate mounting accessory (like FA flange or TC trunnion). Note that the adjustable air cushions only decelerate the piston at stroke end; they do not lock the load. If pressure drops, the rod will drift, so specify an external pilot-operated check valve or the SAIL lock variant for fail-safe holding.
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.
