About the Airtac SAI160 Standard Cylinder SAI160BX210S
The AirTAC SAI160X210-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 14074N push force at 0.7 MPa, this 160mm bore unit is tailored for high-load handling. The 210mm stroke is a non-standard, made-to-order length, ensuring exact fitment for specialized machinery envelopes where standard increments fall short. It features a PT tapered port thread and a SUS304 stainless steel rod (code B) for superior corrosion resistance in harsh environments.
Equipped with a magnetic piston (-S), the extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE or DMSE reed switches. Adjustable air cushions at both ends absorb kinetic energy, while the tie-rod-less profile design maintains a clean, modern exterior. It is dimensionally interchangeable per ISO 15552, serving as a seamless direct replacement for other ISO 15552 profile cylinders.

Where the Airtac SAI160 Standard Cylinder SAI160BX210S Is Used
Heavy Metal Stamping
Provides the 14074N push force required to actuate large stamping presses and forming dies, while the SUS304 rod withstands harsh manufacturing environments.
Automotive Pallet Transfer
Shifts heavy engine block pallets along assembly lines, utilizing the adjustable cushions to safely stop massive moving loads at stroke end.
Large Mold Handling
Positions heavy injection molds within machining centers, where the non-standard 210mm stroke perfectly matches the required mold extraction clearance.
Is the Airtac SAI160 Standard Cylinder SAI160BX210S the Right Cylinder?
Select this 160mm bore when applications require substantial thrust between the 100mm (5497N push at 0.7 MPa) and 200mm (21991N push at 0.7 MPa) classes. The non-standard 210mm stroke is ideal when a 200mm travel is slightly insufficient and 250mm would overextend the machine cavity. For any stroke of 300mm or more, side-load and rod-bearing bending become critical concerns; you must manage lateral forces using an external guide rail or a fully guided cylinder to prevent premature seal wear and rod deformation.
Because this is a double-acting cylinder, it relies on continuous air pressure to hold position. If the air supply drops or the valve centers, the piston will drift; for fail-safe load holding without live pressure, integrate the SAIL (air-released lock) variant or an external rod lock. To mount this as a direct ISO 15552 replacement, use the 160mm bore, 210mm stroke, G3/4 PT port, TC trunnion or FA flange accessory, and ensure the -S magnet is specified for position sensing.

- ✓ 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.
