About the Airtac SAI160 Standard Cylinder SAI160BX155
The AirTAC SAI160X155 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty motion tasks. It generates 10053N of push force and 9425N of pull force at 0.5 MPa, making it well-suited for high-thrust automation lines. The 155mm stroke provides substantial travel for pressing, lifting, or heavy load transfer. Built with an extruded aluminum barrel, this model omits tie-rods for a clean exterior while maintaining strict dimensional interchangeability per ISO 15552 standards.
This specific configuration features a SUS304 stainless steel piston rod (option B), providing excellent corrosion resistance for humid or chemically exposed environments. It utilizes PT tapered port threads, and because no magnet option (-S) is specified, it is optimized for pure pneumatic actuation without sensor track requirements. For operations needing fail-safe load holding, the related SAIL series integrates an air-released lock mechanism.

Where the Airtac SAI160 Standard Cylinder SAI160BX155 Is Used
Heavy-Duty Stamping
Provides the 10053N push force required to form and stamp thick metal components in automated fabrication cells.
Large Press Tending
Handles the 155mm stroke and robust load transfer needed to unload heavy parts from industrial hydraulic presses.
Pallet Diversion
Shifts heavy-loaded pallets along high-throughput material handling conveyors where high lateral thrust is necessary.
Is the Airtac SAI160 Standard Cylinder SAI160BX155 the Right Cylinder?
Selecting this 160mm bore over the neighboring 125mm bore increases your 0.5 MPa push thrust from 6136N to 10053N, a significant jump for heavier machinery. Conversely, dropping to the 125mm bore saves space if your application requires less than 6000N. At 155mm stroke, side-load stress on the rod bearing is moderate, but ensuring proper load alignment remains critical to prevent premature seal wear.
This cylinder uses a PT G3/4 port thread and a M36x2 piston rod thread. It supports standard ISO 15552 mounting accessories like FA flanges or TC trunnions. Remember that a standard SAI cylinder relies on adjustable air cushions at both ends to decelerate the piston; it does not lock or hold loads pneumatically. If your application drops air pressure and requires the load to stay fixed, you must integrate an external pilot-operated check valve or specify the SAIL locking variant.
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 SAI160BX155 FAQ
At an operating pressure of 0.5 MPa, the SAI160X155 generates 10053N of push force and 9425N of pull force. At 0.7 MPa, the push force increases to 14074N.
No, the standard SAI cylinder cannot hold a load without live pressure. You should use the SAIL variant with an air-released lock, the BSAI clamp-lock, or an external rod lock for fail-safe position holding.
