About the Airtac SAI80 Standard Air Cylinder SAI80BX15
The AirTAC SAI80X15 is a double-acting ISO 15552 profile cylinder engineered for short-stroke, high-force tasks. It delivers a robust 2513N of push force at 0.5MPa, making it suitable for heavy clamping or pressing operations that require minimal travel distance. As a made-to-order 15mm stroke, it provides exact motion control where standard strokes are too long.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in wet or chemically exposed environments. It utilizes a PT tapered port thread and lacks a magnet, meaning it is optimized purely for mechanical actuation without electronic position feedback.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX15 Is Used
Heavy-Duty Clamping
Generates 2513N of clamping force at 0.5MPa to secure heavy metal castings during CNC machining.
Short-Stroke Pressing
Ideal for inserting bearings or pins into housings where only 15mm of travel is required.
Corrosive Environments
The SUS304 stainless steel rod withstands moisture and washdowns in food processing or packaging lines.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX15 the Right Cylinder?
Select this 80mm bore when an application demands high thrust within a very compact stroke window. If your clamping force requirements are lower, stepping down to a 63mm bore yields 1559N at 0.5MPa, which may be sufficient and save space. Because the stroke is only 15mm, side-load stress on the rod bearing is negligible compared to longer strokes.
This SAI80X15 variant features a PT port thread and no magnet (-S omitted). It serves as a dimensionally interchangeable direct replacement per ISO 15552 mounting interfaces. Remember that standard SAI cylinders rely on live air pressure to hold position; if your process requires fail-safe load holding without air, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants.
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 SAI80 Standard Air Cylinder SAI80BX15 FAQ
At 0.5MPa, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7MPa, the push force increases to 3518N.
Yes, the SAI series is dimensionally interchangeable per ISO 15552 profile-barrel standards. You can drop it in to replace other ISO 15552 cylinders using standard mounting accessories like FA flanges or TC trunnions.
