About the Airtac SAI160 Standard Cylinder SAI160BX250S
The AirTAC SAI160X250-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a push force of 10053 N at 0.5 MPa, it handles substantial payloads with ease. The 250 mm stroke provides ample extension for large presses and material handling systems.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE/DMSE sensor integration. Fluid is filtered air, operating pressure ranges 0.15-1.0 MPa, and variable air cushions at both ends manage deceleration.

Where the Airtac SAI160 Standard Cylinder SAI160BX250S Is Used
Heavy Metal Stamping
Provides the 10053 N push force required to actuate large mechanical stamping presses and form thick gauge metal components.
Automotive Assembly Jigs
The SUS304 rod resists coolant and shop fluids, making it ideal for positioning heavy chassis subframes on automotive lines.
Bulk Material Diversion
Uses the 250 mm stroke to pivot heavy diverter arms on high-capacity bulk conveyor belts routing aggregates or ores.
Is the Airtac SAI160 Standard Cylinder SAI160BX250S the Right Cylinder?
Choose this 160 mm bore when 125 mm (6136 N at 0.5 MPa) lacks the thrust for your heaviest jigs, but avoid stepping up to the 200 mm bore (15708 N) if you want to minimize air consumption. The 250 mm stroke is well within the 1500 mm standard limit, yet side loads must be controlled. Long unsupported rods bend under lateral stress; use an external guide or a fully guided cylinder to prevent rod-bearing wear.
For direct replacements, match the 160 mm bore, 250 mm stroke, G3/4 PT ports, and your required mounting accessory (like TC trunnion). Because this is a standard double-acting cylinder, it cannot hold a load if air pressure drops. For fail-safe position holding, specify the SAIL lock or BSAI clamp-lock variant instead of relying on the cushions.
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 SAI160BX250S FAQ
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. At 0.7 MPa, the push force increases to 14074 N.
Yes. The SAI160X250-S is dimensionally interchangeable per ISO 15552. Match the 160 mm bore, 250 mm stroke, and G3/4 port for a direct replacement.
