About the Airtac SAI160 Standard Cylinder SAI160AX650S
The AirTAC SAI160X650-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. At 0.7 MPa, it generates a substantial push force of 14074 N and a pull force of 9425 N at 0.5 MPa, making the 650 mm stroke well-suited for moving massive payloads through long linear cycles. The extruded aluminum barrel design omits tie rods, providing a clean exterior that conforms to ISO 15552 dimensional interchangeability.
This specific configuration includes a -S magnet for direct mounting of CMSE or DMSE sensor switches along the dual lateral grooves. It is built with an SUS420J2 stainless steel piston rod for superior corrosion resistance compared to standard carbon steel. Fluid connections use PT tapered threads, and adjustable air cushions at both ends absorb kinetic energy at the stroke limits.

Where the Airtac SAI160 Standard Cylinder SAI160AX650S Is Used
Heavy Stamping Press
Provides the high tonnage and long 650 mm reach needed to actuate large metal forming dies and heavy stamping presses.
Automotive Assembly Jig
Shifts heavy chassis or powertrain components along extended travel distances, utilizing the 14074 N push force to move structural parts.
Pallet Transfer Indexer
Indexes loaded pallets through automated warehousing lines, relying on adjustable end cushions to stop massive weights smoothly.
Is the Airtac SAI160 Standard Cylinder SAI160AX650S the Right Cylinder?
Selecting this 160 mm bore is appropriate when 125 mm bore maxes out at 8590 N push force at 0.7 MPa, but you need the 14074 N output to shift heavy assemblies. Because the 650 mm stroke creates a long unsupported rod extension, side loads can cause severe rod-bearing bending. For this geometry, utilizing an external guide rail or choosing a fully guided cylinder is strongly recommended to prevent premature seal wear and binding.
If the machine loses air pressure, this cylinder cannot hold its load and will drift downward. For suspended or vertical applications requiring fail-safe holding, integrate the SAIL pneumatic lock variant or an external rod lock. To mount this unit as a direct replacement per ISO 15552, use the TC trunnion or FA flange accessories, and ensure your pneumatic supply connects to the G3/4 ports.
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 SAI160 Standard Cylinder SAI160AX650S FAQ
At a 0.7 MPa operating pressure, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N at 0.5 MPa.
Yes, the SAI160X650-S is dimensionally interchangeable per ISO 15552. You can use it as a direct replacement for other ISO 15552 profile cylinders of the same bore and stroke, matching the G3/4 port and mounting interface.
