About the Airtac SAI100 Standard Air Cylinder SAI100AX155
The AirTAC SAI100X155 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 155mm stroke. It delivers a robust 3927 N of push force at 0.5 MPa, scaling up to 5497 N at 0.7 MPa, making it well-suited for heavy-duty positioning tasks. This specific 155mm stroke is a non-standard, made-to-order length designed for specialized mid-range travel requirements.
Beyond the standard spec table, this unit is configured with a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance over standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for CMSE or DMSE switches, though this specific SKU omits the internal magnet. The piston seals utilize standard TPU polyurethane, but Viton (H) options are available for high-temperature environments up to 70 C.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX155 Is Used
Heavy Stamping
Provides the 5497 N force at 0.7 MPa needed to actuate heavy stamping and forming presses in metal fabrication lines.
Pallet Diverting
Drives robust diverters and sorting gates on high-mass conveyor systems where a 155mm stroke is required to clear the load.
Automated Press
Ideal for automated assembly presses requiring high thrust over a specific, non-standard 155mm travel distance.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX155 the Right Cylinder?
Selecting this bore size is appropriate when 50mm or 63mm cylinders lack thrust, stepping up from the 63mm bore's 1559 N at 0.5 MPa to a massive 3927 N. At a 155mm stroke, the unsupported rod length is moderate, but operators should still minimize lateral loads to prevent rod-bearing wear; using external guide rails ensures smooth linear travel. Because this is a double-acting cylinder, it does not hold position pneumatically if air pressure drops; for fail-safe load holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants instead of relying on the end cushions.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders without tying you to a specific brand's proprietary footprint. This specific configuration uses PT tapered G1/2 ports and a SUS420J2 rod. If you need position feedback, select the SAI100X155-S variant with the internal magnet installed.

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 SAI100AX155 FAQ
