About the Airtac SAI100 Standard Air Cylinder SAI100X85S
The AirTAC SAI100X85-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N of push force at 0.5 MPa, this 100 mm bore unit paired with an 85 mm stroke excels in high-thrust clamping and pressing tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
Equipped with a -S magnet, this model seamlessly integrates with CMSE and DMSE sensor switches via the dual-side sensor grooves for precise end-of-stroke detection. The standard carbon steel piston rod ensures high tensile strength and durability, while the adjustable air cushions at both ends absorb impact energy efficiently across its 30-800 mm/s operating speed range.

Where the Airtac SAI100 Standard Air Cylinder SAI100X85S Is Used
Heavy-Duty Stamping
Provides the 3927 N push force required to form and stamp thick-gauge metal components in automated press lines.
Pallet Diverting
Actuates heavy diverting arms on high-mass conveyor systems, using the 85 mm stroke to reroute loaded pallets efficiently.
Industrial Clamping
Secures large weldments and castings during machining operations, maintaining rigid positioning under heavy cutting forces.
Is the Airtac SAI100 Standard Air Cylinder SAI100X85S the Right Cylinder?
Selecting this 100 mm bore over a smaller 80 mm option upgrades your thrust from 2513 N to 3927 N at 0.5 MPa, making it ideal when a lighter cylinder stalls under high loads. Conversely, stepping up to a 125 mm bore yields 6136 N if your application demands even greater pressing power. The 85 mm stroke is optimal for short-travel, high-force operations.
Because the stroke is under 300 mm, side-load bending stress on the rod bearing is minimal. However, remember that the standard SAI cannot hold a load if air pressure drops; the adjustable cushion only decelerates the piston near the end of travel rather than locking it. For position-holding safety, consider the SAIL (air-released lock) variant or an external pilot-operated check valve. This model features a PT tapered G1/2 port, uses standard mounting accessories like FA flanges or TC trunnions, and includes the -S magnet for sensing.

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 SAI100 Standard Air Cylinder SAI100X85S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes, it is a genuine AirTAC ISO 15552 profile cylinder. Its standardized mounting dimensions and G1/2 PT ports make it dimensionally interchangeable with other ISO 15552 cylinders, allowing for a seamless drop-in replacement.
