About the Airtac SAI80 Standard Air Cylinder SAI80X1650
The AirTAC SAI80X1650 is a double-acting ISO 15552 profile cylinder featuring a robust extruded aluminum barrel. It delivers a thrust of 2513 N at 0.5 MPa, making it well-suited for heavy-duty positioning over long distances. Because the requested stroke of 1650 mm exceeds the standard maximum of 1500 mm, this unit is configured as a made-to-order component.
This variant incorporates a standard carbon steel piston rod for high tensile strength under extended reach. The barrel includes integrated sensor grooves on both sides, allowing for straightforward position tracking when paired with a compatible magnet-equipped variant. Its PT tapered port threads ensure a dependable, leak-free pneumatic connection in demanding industrial environments.

Where the Airtac SAI80 Standard Air Cylinder SAI80X1650 Is Used
Extended Reach Press
Drives large platens across wide machinery beds where a 1650 mm stroke is required to clear bulky workpieces during automated press cycles.
Material Transfer
Actuates heavy pallet lifts or pushers in automated warehousing, moving goods between parallel conveyor lines over extended gaps.
Long-Stroke Ejection
Ejects finished parts or scrap from deep-draw presses, utilizing the 2513 N push force to clear large dies safely.
Is the Airtac SAI80 Standard Air Cylinder SAI80X1650 the Right Cylinder?
Selecting this bore size is optimal when the 63mm class (1402 N pull at 0.5 MPa) is insufficient to overcome system friction, yet the 100mm class is oversized for the available space. For a stroke length of 1650 mm, the extended rod is highly susceptible to bending under side loads. To prevent premature guide-ring wear and rod-bearing failure, always pair this cylinder with an external linear guide or utilize a twin-rail guided cylinder design.
This model is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders. It utilizes a G3/8 port, an M20x1.5 rod thread, and supports mounting accessories such as the LB foot, FA flange, and TC trunnion. Note that this standard cylinder does not hold its load upon air loss; if vertical load holding is required, specify the SAIL or BSAI clamp-lock variant.
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.
