About the Airtac SAI100 Standard Air Cylinder SAI100X425S
The AirTAC SAI100X425-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 5497 N of push force at 0.7 MPa, this 100 mm bore actuator is built to handle substantial loads across its 425 mm stroke. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that resists contamination in demanding industrial environments.
This specific configuration includes a magnetic piston (-S) for precise position detection using CMSE or DMSE switches, which seat neatly into the sensor grooves machined on both sides of the barrel. The standard carbon steel piston rod offers high tensile strength for reliable operation, while the G1/2 PT tapered port ensures a secure, leak-free pneumatic connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100X425S Is Used
Pallet Diversion
Provides the necessary push force to redirect heavy loaded pallets onto secondary conveyor lines without stalling.
Press Ejection
Extends rapidly to eject finished metal components from a hydraulic press bed, using the full 425 mm stroke to clear the tooling area.
Carton Sorting
Actuates large sorting arms in high-throughput distribution centers, moving heavy freight cartons into designated chutes.
Is the Airtac SAI100 Standard Air Cylinder SAI100X425S the Right Cylinder?
Selecting this 100 mm bore actuator makes sense when your application requires significantly more thrust than a 63 mm bore can provide (2182 N at 0.5 MPa), but you want to avoid the heavier physical envelope and air consumption of a 125 mm cylinder. The 425 mm stroke provides ample extension for mid-range material handling tasks.
Because this model features a 425 mm stroke, the extended rod is susceptible to bending under lateral loads; utilize an external guide rail or a guided cylinder to prevent premature rod-bearing wear. Note that the adjustable air cushions at both ends decelerate the piston to prevent end-cap impact, but they do not lock the load—if your system loses air pressure, you must integrate an external rod lock or use a SAIL variant to hold position safely. This unit is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders when matching the 100 mm bore, 425 mm stroke, G1/2 port, and FA flange or LB foot mounting accessories.
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 SAI100 Standard Air Cylinder SAI100X425S FAQ
At a standard operating pressure of 0.7 MPa, this 100 mm bore cylinder generates 5497 N of push force and 3681 N of pull force. If pressure is increased to 0.9 MPa, the push force reaches 7068 N.
Yes, the SAI100X425-S is manufactured to the ISO 15552 standard, meaning its mounting dimensions are fully interchangeable with other ISO 15552 profile cylinders of the same bore and stroke. You can use the existing FA, FB, LB, or TC mounting accessories.
