About the Airtac SAI100 Standard Air Cylinder SAI100AX550
The AirTAC SAI100X550 is a double-acting ISO 15552 profile cylinder featuring a 100 mm bore and a 550 mm stroke. It generates 3927 N of push force at 0.5 MPa and 5497 N at 0.7 MPa, making it well-suited for heavy-duty positioning and high-thrust automation tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops directly into standard ISO 15552 mounting interfaces.
This specific configuration is built with a SUS420J2 stainless steel rod for enhanced durability against moisture and general corrosion. It utilizes PT tapered port threads, and because a magnet is not specified, it operates without sensor detection out of the box. You can easily add position feedback later by specifying the -S variant to utilize the dual sensor grooves on the barrel for CMSE or DMSE switches.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX550 Is Used
Heavy Duty Stamping
Provides 5497 N of thrust at 0.7 MPa for pressing, riveting, and assembling metal components in automated fabrication lines.
Pallet Diversion
Extends 550 mm to push heavy pallets or product totes from a main conveyor belt onto secondary processing tracks.
Large Door Actuation
Drives the opening and closing of heavy industrial machine guarding doors or large access panels on automated equipment.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX550 the Right Cylinder?
Choose this 100 mm bore when an 80 mm cylinder lacks thrust—the 80 mm yields 2513 N at 0.5 MPa, whereas this SAI100X550 provides 3927 N at the same pressure. If your application requires less force, stepping down saves space and air consumption. Because this stroke is 550 mm, the extended rod is highly susceptible to bending under side loads; always use an external guide rail or a guided cylinder to prevent premature rod-bearing wear.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a seamless drop-in replacement for other ISO 15552 profile cylinders. To match this exact configuration, specify a 100 mm bore, 550 mm stroke, PT G1/2 port, and the SUS420J2 rod material. Note that the standard SAI does not hold its position if air pressure is lost; for suspended loads that require fail-safe holding, consider the SAIL (air-released lock) or BSAI (bidirectional 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.
Airtac SAI100 Standard Air Cylinder SAI100AX550 FAQ
