About the Airtac SAI80 Standard Air Cylinder SAI80X85
The AirTAC SAI80X85 is a double-acting ISO 15552 profile cylinder engineered to deliver 2513 N of push force at 0.5 MPa. The 85 mm stroke makes it highly effective for short-travel clamping, pressing, and ejection tasks where high force is required in a compact movement range. Its extruded aluminum barrel design strictly adheres to the ISO 15552 mounting interface, ensuring it serves as a drop-in replacement for other ISO 15552 profile cylinders without requiring structural machine modifications.
This specific configuration features a robust carbon steel piston rod and PT tapered port threading. For environments requiring position feedback, the barrel incorporates dual sensor grooves ready to accept CMSE or DMSE switches, though a magnet (-S option) must be specified for that functionality. If your application demands intermediate load holding upon air loss, consider the SAIL variant equipped with an air-released lock.

Where the Airtac SAI80 Standard Air Cylinder SAI80X85 Is Used
Heavy-Duty Stamping
Provides the robust 2513 N force required to seat pins, rivets, or small stampings in metal fabrication assemblies.
Product Diversion
Acts as a heavy-duty diverter arm on packaging lines, using the 85 mm stroke to push heavier products cleanly off a conveyor belt.
Pallet Clamping
Secures standard pallets or heavy workpieces at machining stations, utilizing the high force and short stroke for rigid holding.
Is the Airtac SAI80 Standard Air Cylinder SAI80X85 the Right Cylinder?
Selecting this 80 mm bore over the smaller 63 mm bore (which provides 1559 N push at 0.5 MPa) is necessary when your application requires substantially higher thrust within a short stroke. If the 85 mm stroke provides excessive travel, stepping down to a 50 mm bore (982 N at 0.5 MPa) might suit lighter-duty tasks. Because the stroke is only 85 mm, side-load stress on the rod bearing is minimal, though external guides are always recommended for rigid lateral loads.
As a true ISO 15552 standard cylinder, replacement matching is straightforward: verify an 80 mm bore, 85 mm stroke, G3/8 port, and select appropriate mounting accessories like FA flanges or TC trunnions based on your kinematic needs. Note that this standard SAI model does not hold position when air pressure is exhausted; the adjustable air cushions only decelerate the piston at stroke ends.
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 SAI80X85 FAQ
At 0.5 MPa, the SAI80X85 provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
Yes. The SAI80X85 is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 cylinders of the same bore size. Just match your G3/8 port and mounting accessories.
