About the Airtac SAI100 Standard Air Cylinder SAI100BX155S
The AirTAC SAI100X155-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty positioning. It provides a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa, making it well-suited for mid-stroke actuation tasks requiring substantial thrust. The 155 mm stroke offers a compact extension length for machinery with spatial constraints.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance in humid or washdown environments. Equipped with a built-in magnet (-S), it seamlessly integrates with CMSE and DMSE sensor switches mounted in the dual side grooves of the extruded aluminum barrel. Fluid connections use PT tapered threads, and adjustable air cushions at both ends ensure smooth deceleration of large payloads.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX155S Is Used
Heavy Stamping Press
Provides the 3927 N push force required to actuate heavy forming dies and stamping assemblies at 0.5 MPa operating pressure.
Large Clamp Actuation
Ideal for securing heavy industrial workpieces, utilizing the SUS304 rod to resist corrosion in demanding manufacturing environments.
Pallet Diverting
Drives robust routing gates on high-capacity conveyor lines, using adjustable air cushions to smoothly stop the 155 mm stroke.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX155S the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant significantly increases output, stepping up from 2513 N to 3927 N at 0.5 MPa. If your application requires less force and faster cycling, dropping to the 80 mm bore is advisable. Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal compared to longer extensions, though standard alignment practices should still be followed.
As a true ISO 15552 profile cylinder, this unit serves as a drop-in replacement for any standard cylinder sharing the same 100 mm bore, 155 mm stroke, G1/2 port, and mounting dimensions. It does not hold position automatically upon air loss; for applications requiring static locking during exhaust or valve centering, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants instead of relying on the cushion.
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 SAI100 Standard Air Cylinder SAI100BX155S FAQ
At 0.5 MPa, this 100 mm bore cylinder provides a push force of 3927 N and a pull force of 3681 N. If pressure is increased to 0.7 MPa, the push force reaches 5497 N.
Yes, the SAI100X155-S is dimensionally interchangeable per ISO 15552. It shares standard mounting interfaces and G1/2 port sizing, allowing it to serve as a drop-in replacement for equivalent ISO 15552 profile cylinders.
