About the Airtac SAI160 Standard Cylinder SAI160BX425S
The AirTAC SAI160X425-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial push force of 10053 N at 0.5 MPa, this 160 mm bore unit is built to move massive loads across its 425 mm stroke. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies the mounting of accessories and sensor switches.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet (-S) for use with CMSE and DMSE position switches. The barrel features sensor grooves on both sides, while adjustable air cushions at both ends absorb kinetic energy. For environments requiring elevated temperature resistance, the standard TPU seals can be swapped for Viton (H) or NBR (N) alternatives.

Where the Airtac SAI160 Standard Cylinder SAI160BX425S Is Used
Heavy Stamping
Provides the 10053 N push force required to actuate large mechanical presses and form thick metal components.
Injection Molding
Rugged 160 mm bore handles core pulling and heavy mold ejection duties where high kinetic energy is present.
Pallet Diversion
Shifts fully loaded industrial pallets along high-throughput packaging lines using adjustable end cushions to soften stops.
Is the Airtac SAI160 Standard Cylinder SAI160BX425S the Right Cylinder?
Selecting this 160 mm bore is ideal when a 125 mm cylinder falls short—generating 10053 N of push force at 0.5 MPa compared to the 125 mm bore's 6136 N. Stepping up to a 200 mm bore yields 15708 N but demands a larger G3/4 port footprint. This model uses PT tapered ports and operates at 30-500 mm/s.
Because the 425 mm stroke creates a long unsupported rod extension, side loads can cause severe rod-bearing bending and premature wear. Implement an external guide rail or choose a guided cylinder to absorb lateral forces. Furthermore, a standard double-acting cylinder drifts when air pressure is removed; if the application requires dead-stop holding under zero pressure, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead of relying on the cushion.
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 SAI160BX425S FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 14074 N.
Yes. The SAI160X425-S is dimensionally interchangeable per ISO 15552, meaning it shares standard mounting dimensions with other ISO 15552 profile cylinders. It uses a G3/4 port and accepts standard FA, LB, and TC mounting accessories.
