About the Airtac SAI80 Standard Air Cylinder SAI80BX155S
The AirTAC SAI80X155-S is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 2513N of push force at 0.5 MPa. Its 155mm stroke is well-suited for mid-range automation tasks requiring substantial linear movement. The extruded aluminum barrel omits tie-rods, providing a clean exterior that simplifies the mounting of accessories.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance in harsh environments. It includes a built-in magnet (-S) for seamless integration with CMSE or DMSE sensor switches along the dual barrel grooves. PT tapered threads ensure a secure, leak-free pneumatic connection.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX155S Is Used
Automated Pressing
Provides 2513N of push force at 0.5 MPa for assembling components and light stamping operations.
Material Diverting
Drives robust diverters and sorting gates on high-throughput packaging conveyors.
Clamp Fixturing
Secures heavy workpieces during machining or welding processes using its 80mm bore power.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX155S the Right Cylinder?
If your application requires less force, stepping down to the 63mm bore yields 1559N at 0.5 MPa, while moving up to the 100mm bore provides 3927N for heavier loads. Because this 155mm stroke is under 300mm, side-load stress on the rod bearing is minimal, though external guides are still recommended for highly offset loads.
This model is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other standard profile cylinders. To hold a load securely without live air pressure, pair this cylinder with an external pilot-operated check valve or specify the SAIL lock variant, as the adjustable air cushions only decelerate the piston and do not act as a brake.
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.
