About the Airtac SAI80 Standard Air Cylinder SAI80BX260S
The AirTAC SAI80X260-S is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and a 260mm stroke. It generates a substantial push force of 2513 N at 0.5 MPa, extending to 3518 N at 0.7 MPa, making it well-suited for demanding mid-to-heavy automation tasks.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet for use with CMSE and DMSE sensor switches along the dual-sided barrel grooves. Fluid ports are PT tapered thread type, and the cylinder incorporates adjustable air cushions at both ends to manage impact deceleration.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX260S Is Used
Heavy-Duty Clamping
Provides 2513 N of push force at 0.5 MPa to secure large metal castings or heavy components during CNC machining operations.
Pallet Indexing
Uses the 260mm stroke to push and position heavy loaded pallets along roller conveyors in packaging lines.
Press Fit Assembly
Delivers consistent thrust to press bearings or bushings into housings on automated assembly machinery.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX260S the Right Cylinder?
Selecting this 80mm bore over the smaller 63mm option upgrades your push force from 1559 N to 2513 N at 0.5 MPa, while stepping up to the 100mm bore yields 3927 N for heavier loads. The 260mm stroke provides ample travel for clamping, lifting, or indexing mechanisms.
Because this stroke exceeds 300mm is not met here, but at 260mm side loads should still be managed with proper rod-bearing alignment. If the application requires holding a load vertically when air pressure is removed, note that the standard adjustable cushion only decelerates the piston and does not act as a lock; consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock for secure position holding. This genuine AirTAC unit serves as a direct dimensional direct replacement for other ISO 15552 profile cylinders.
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 SAI80BX260S FAQ
At 0.5 MPa, the cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
No, the standard SAI cylinder does not hold position without live pressure. You should use the SAIL variant with an air-released lock or an external rod lock for secure vertical load holding.
