About the Airtac SAI160 Standard Cylinder SAI160BX115S
The AirTAC SAI160X115-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 14074 N push force at 0.7 MPa, this 160 mm bore unit is built to handle substantial loads. The integrated magnet allows seamless operation with CMSE and DMSE sensor switches via the dual-sided barrel grooves. This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and includes a 115 mm stroke.
As a genuine ISO 15552 standardized cylinder, it provides a direct mounting interface replacement for other ISO 15552 profile cylinders. The adjustable air cushions at both ends ensure smooth deceleration of high-mass loads. For environments requiring elevated thermal stability, the standard TPU seals can be swapped for Viton (H) or NBR (N) options.

Where the Airtac SAI160 Standard Cylinder SAI160BX115S Is Used
Automotive Stamping
Provides the high thrust force needed to form and secure heavy-gauge metal panels during automated press operations.
Heavy Material Lift
Actuates robust lifting arms for positioning heavy castings or billets within machining centers.
Pallet Diversion
Pushes fully loaded pallets across high-throughput packaging lines without stalling under mass.
Is the Airtac SAI160 Standard Cylinder SAI160BX115S the Right Cylinder?
Select this 160 mm bore when the 100 mm bore (offering 5497 N push at 0.7 MPa) cannot meet your force requirements, but you want to avoid stepping up to a massive 200 mm body. The PT tapered port threads ensure a tight, leak-free pneumatic connection in high-flow scenarios. Because the stroke is 115 mm, side-load stress on the rod bearing is moderate, though external guides are recommended if absorbing offset loads.
This standard double-acting cylinder relies on live air pressure to move and hold its position; it will drift if air is exhausted. If your fixture must retain a load safely during a pressure drop, integrate an external pilot-operated check valve or specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant. To guarantee proper ISO 15552 interchangeability, match the 160 mm bore, 115 mm stroke, PT port threads, and the -S magnet option when sourcing replacement parts.
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 SAI160BX115S FAQ
This 160 mm bore cylinder provides 10053 N of push force at 0.5 MPa and 14074 N at 0.7 MPa. The pull force at 0.5 MPa is 9425 N.
No. The standard SAI cylinder relies on live air pressure and will drift downwards if pressure is lost. For fail-safe load holding, use the SAIL (with lock) or BSAI (clamp-lock) variants.
