About the Airtac SAI160 Standard Cylinder SAI160BX850S
The AirTAC SAI160X850-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations. It generates a substantial push force of 10053 N at 0.5 MPa, extending across an 850 mm stroke to handle massive positioning tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies cleaning and maintenance in demanding industrial environments.
This specific configuration features a SUS304 stainless steel rod (material code B) for superior corrosion resistance, alongside a built-in magnet (-S) that enables direct mounting of CMSE or DMSE sensor switches along the dual grooves on the barrel. It utilizes PT tapered port threads and includes adjustable air cushions at both ends to absorb kinetic energy during high-mass movements.

Where the Airtac SAI160 Standard Cylinder SAI160BX850S Is Used
Heavy Machinery Forming
Supplies the 14074 N thrust at 0.7 MPa required to actuate large forming presses and heavy-duty stamping equipment over long travel distances.
Automotive Assembly Jigs
Moves large structural fixtures and vehicle chassis components along the 850 mm stroke, utilizing the SUS304 rod to resist workshop moisture and coolant exposure.
Bulk Material Diverter
Actuates heavy-duty diverter gates on high-capacity mining or aggregate conveyors, where the robust 160 mm bore handles substantial material resistance.
Is the Airtac SAI160 Standard Cylinder SAI160BX850S the Right Cylinder?
Choosing this 160 mm bore is appropriate when 100 mm bore cylinders (providing 3927 N at 0.5 MPa) lack the thrust for your heavy load, but a 200 mm bore (15708 N at 0.5 MPa) would be excessive. Because this model features an 850 mm stroke, the extended rod is highly susceptible to bending under side loads. To prevent premature seal failure and rod-bearing wear, mount the load on an external linear guide rail rather than relying on the piston rod for radial support.
As a true ISO 15552 standard cylinder, this unit is dimensionally interchangeable with other ISO 15552 profile cylinders, matching the exact mounting footprint for front flange (FA/FB) or rear clevis (CA/CB) accessories. Remember that standard double-acting cylinders do not hold loads safely upon air loss; if your application requires vertical drop prevention, select the SAIL locking variant or an external rod lock.
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 SAI160BX850S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a theoretical push force of 14074 N and a pull force of 9425 N. The maximum theoretical force at 1.0 MPa is 2050 kgf.
Yes, the SAI series is built to the ISO 15552 standard, making its mounting dimensions a direct replacement for other ISO 15552 profile cylinders. You can use standard FA, FB, CA, or TC mounting accessories without modifying your machine frame.
