About the Airtac SAI100 Standard Air Cylinder SAI100X425
The AirTAC SAI100X425 is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 3927 N of push force at 0.5 MPa. Its 425 mm stroke is well-suited for automated machinery requiring substantial linear displacement over a medium distance. The extruded aluminum barrel omits traditional tie-rods, providing a smooth exterior that simplifies cleaning and reduces contamination traps in demanding environments.
To enhance longevity in dynamic operations, this configuration features a standard carbon steel piston rod. For environments with elevated thermal demands, the cylinder can be specified with Viton (H) seals to withstand higher operating temperatures, while the dual sensor grooves on the barrel accept CMSE or DMSE switches when a magnet (-S) is added.

Where the Airtac SAI100 Standard Air Cylinder SAI100X425 Is Used
Automotive Body Welding
Provides the high clamping force and extended reach needed to hold large automotive panels securely in place during robotic welding procedures.
Pallet Transfer Systems
Drives heavy pallets along extended conveyor sections, utilizing the 425 mm stroke to shift loads between adjacent processing stations.
Large Component Ejection
Ejects molded or machined components from heavy-duty presses, using the 100 mm bore's 3927 N thrust to push dense parts clear of the machinery.
Is the Airtac SAI100 Standard Air Cylinder SAI100X425 the Right Cylinder?
When selecting this actuator, consider stepping down to the 80 mm bore if your application only requires 2513 N of push force at 0.5 MPa, as the smaller footprint saves valuable mounting space. Conversely, if your load demands exceed 3927 N, upgrading to the 125 mm bore yields 6136 N of thrust. Because the 425 mm stroke creates a long unsupported rod extension, side-load induced bending on the rod bearing is a primary concern; utilizing an external guide rail or a guided cylinder design is strongly recommended to prevent premature seal wear.
This unit features a G1/2 PT tapered port and adheres strictly to ISO 15552 mounting dimensions, making it a direct drop-in replacement for any standard ISO 15552 cylinder. Note that the adjustable air cushions at both ends decelerate the piston near stroke end but do not lock the load; if position holding is required upon loss of air pressure, explore the SAIL or BSAI clamp-lock variants.
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.
