About the Airtac SAI80 Standard Air Cylinder SAI80X25
The AirTAC SAI80X25 is a double-acting ISO 15552 profile cylinder engineered for tasks requiring substantial force in a minimal stroke distance. It delivers a push force of 2513 N and a pull force of 2268 N at 0.5 MPa, making it well-suited for short, powerful clamping or pressing operations.
This unit features a standard carbon steel piston rod and utilizes PT tapered port threads for secure pneumatic connections. Because a magnet is not specified, it operates without integrated position sensing; add the -S option if your control system requires CMSE or DMSE switches to mount into the dual sensor grooves on the extruded aluminum barrel.

Where the Airtac SAI80 Standard Air Cylinder SAI80X25 Is Used
Heavy-Duty Clamping
Provides 2513 N of clamping force at 0.5 MPa to secure heavy metal workpieces during aggressive machining operations.
Short-Stroke Pressing
Ideal for inserting bearings or pins into housings where a brief 25 mm travel distance and high impact force are required.
Product Diversion
Drives robust diverters or lifting gates on high-mass conveyor lines, moving heavy goods efficiently within a compact space.
Is the Airtac SAI80 Standard Air Cylinder SAI80X25 the Right Cylinder?
Select this 80 mm bore when an application demands more thrust than a 63 mm cylinder (1402 N pull at 0.5 MPa) can provide, but without the physical envelope of a 100 mm unit. The 25 mm stroke is optimal for extremely short movements where maintaining a compact overall length is critical.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 cylinders matching the 80 mm bore, 25 mm stroke, G3/8 port, and standard mounting accessories like FA flanges or TC trunnions. Remember that standard double-acting cylinders drift when air pressure is removed; choose the SAIL variant if the mechanism must mechanically hold a load during an air loss event.
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 SAI80X25 FAQ
At an operating pressure of 0.5 MPa, this 80 mm bore cylinder provides a push force of 2513 N and a pull force of 2268 N. At 0.7 MPa, the push force increases to 3518 N.
Yes, the SAI80X25 is built to the ISO 15552 standard, making its mounting dimensions interchangeable with other ISO 15552 profile cylinders of the same bore and stroke. Ensure your port size matches the G3/8 specification.
