About the Airtac SAI160 Standard Cylinder SAI160BX85
The AirTAC SAI160X85 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a robust push force of 10053 N at 0.5 MPa, making it well-suited for short-stroke pressing and clamping operations.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing for easy position feedback when paired with a compatible magnet-equipped variant.

Where the Airtac SAI160 Standard Cylinder SAI160BX85 Is Used
Heavy-Duty Pressing
Applies 10053 N of push force at 0.5 MPa for assembling bearings and heavy mechanical components.
Industrial Clamping
Secures large fabricated steel frames during welding or machining using its robust 160 mm bore.
Injection Molding Ejection
Ejects dense plastic or metal parts from molds utilizing the SUS304 stainless steel rod.
Is the Airtac SAI160 Standard Cylinder SAI160BX85 the Right Cylinder?
Selecting this 160 mm bore cylinder is ideal when an 80 mm bore (providing 2513 N at 0.5 MPa) is insufficient for high-force tasks, but a massive 200 mm bore is unnecessary. The 85 mm stroke offers compact actuation for heavy loads.
Because the stroke is under 300 mm, side-load bending on the rod bearing is minimized compared to longer extensions. Note that a standard SAI cylinder relies on adjustable air cushions at both ends to decelerate the piston; it cannot hold a load without continuous air pressure. For dead-end holding requirements, consider the SAIL or BSAI locking variants.
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 SAI160BX85 FAQ
At an operating pressure of 0.5 MPa, the SAI160X85 cylinder delivers a push force of 10053 N and a pull force of 9425 N. At 0.7 MPa, the push force increases to 14074 N.
Yes, the SAI160X85 is dimensionally interchangeable per ISO 15552 standards. It serves as a direct replacement for other ISO 15552 profile cylinders with matching 160 mm bore and 85 mm stroke dimensions.
