About the Airtac SAI160 Standard Cylinder SAI160BX55S
The AirTAC SAI160X55-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a push force of 10053 N and a pull force of 9425 N at 0.5 MPa. This 55 mm stroke variant is purpose-built for short, high-power clamping and pressing tasks. As a genuine AirTAC component, it ensures reliable performance in rigorous industrial environments.
Reflecting its tailored configuration, this unit incorporates a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a built-in magnet (-S) for seamless integration with CMSE or DMSE sensor switches along the dual-sided barrel grooves. Fluid compatibility is maintained via PT tapered port threads, while standard adjustable air cushions at both ends absorb end-of-stroke impact.

Where the Airtac SAI160 Standard Cylinder SAI160BX55S Is Used
Heavy-Duty Stamping
Provides the intense 10053 N impact force required for short-stroke metal forming and stamping operations in automated lines.
Industrial Clamping
Secures large molds or heavy fabricated components during machining, utilizing its robust 160 mm profile barrel to resist deflection.
Injection Molding Ejectors
Delivers reliable high-thrust ejection of dense plastic parts, with the -S magnet enabling precise position confirmation for the control system.
Is the Airtac SAI160 Standard Cylinder SAI160BX55S the Right Cylinder?
Selecting this 160 mm bore cylinder is optimal when an application demands upward of 10000 N of thrust within a compact 55 mm stroke. If a project requires less force, stepping down to the 125 mm bore yields 6136 N at 0.5 MPa, whereas moving up to the 200 mm bore provides 15708 N. Because the stroke is under 300 mm, rod-bearing bending is minimal, though external guides are still recommended if absorbing eccentric loads.
This model serves as a direct, dimensionally interchangeable direct replacement per ISO 15552 mounting interfaces. To match this exact configuration, specify the 160 mm bore, 55 mm stroke, PT port threads, and the -S magnet option. For mounting flexibility, consider FA or FB flanges, or TC trunnion brackets. Note that standard SAI cylinders drift when air pressure is lost; use the BSAI bidirectional clamp-lock variant if the mechanism must hold a load safely without live pressure.
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 SAI160BX55S FAQ
