About the Airtac SAI32 Standard Cylinder SAI32BX650S
The AirTAC SAI32X650-S is a double-acting ISO 15552 profile cylinder engineered for precise linear motion. Delivering a push force of 402 N at 0.5 MPa and 563 N at 0.7 MPa, this 32 mm bore unit utilizes a 650 mm stroke to drive equipment over extended distances. The extruded aluminum barrel omits tie-rods, providing a clean profile that drops directly into standardized ISO 15552 mounting interfaces.
This specific configuration incorporates a SUS304 stainless steel rod (option B) for superior corrosion resistance in humid or washdown environments. It includes a piston magnet (-S) to trigger CMSE or DMSE reed switches along the dual sensor grooves machined into both sides of the barrel. Fluid ports feature PT tapered threads, and adjustable air cushions at both ends absorb end-of-stroke impact to protect your machinery.

Where the Airtac SAI32 Standard Cylinder SAI32BX650S Is Used
Extended Reach Pick & Place
Drives long-traverse handling arms in automated assembly lines, utilizing the 650 mm stroke to transfer components between distant workstations without requiring intermediate stages.
Sorting Diverter
Actuates diverter gates on packaging conveyors, pushing products into secondary lanes over a wide physical span with reliable 402 N force at 0.5 MPa.
Vertical Lifting Stage
Raises lightweight trays or bins in storage systems, where the SUS304 rod provides necessary resilience against ambient humidity in logistics facilities.
Is the Airtac SAI32 Standard Cylinder SAI32BX650S the Right Cylinder?
When sizing this actuator, stepping up to the 40 mm bore increases the 0.5 MPa push force to 628 N for heavier payloads, while dropping to a smaller profile is not advised for this length class. The 650 mm stroke requires careful attention to side-load management; long unsupported rods are prone to bending under lateral stress. To prevent premature rod-bearing wear, implement an external guide rail or select a guided cylinder variant for high-offset loads.
If your mechanism must maintain its vertical position or hold a load when air pressure is exhausted or the valve centers, a standard SAI will drift and drop. For fail-safe holding, specify the SAIL variant with an air-released lock or integrate an external pilot-operated check valve. This model is dimensionally interchangeable per ISO 15552, allowing direct replacement using the existing 32 mm bore footprint, 650 mm stroke, PT port connections, and standard mounting accessories like LB foot or FA flange brackets.
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 SAI32 Standard Cylinder SAI32BX650S FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. When operating at 0.7 MPa, the push force increases to 563 N.
Yes, the SAI32X650-S is dimensionally interchangeable per ISO 15552. You can drop it into existing setups matching the 32 mm bore, 650 mm stroke, and PT port locations without altering the machine frame.
