About the Airtac SAI100 Standard Air Cylinder SAI100AX475
The AirTAC SAI100X475 is a double-acting ISO 15552 profile cylinder engineered to deliver 5497 N of push force at 0.7 MPa. Featuring a 100 mm bore and a 475 mm stroke, it provides the robust linear motion required for heavy-duty industrial handling. The extruded aluminum barrel design omits traditional tie rods, ensuring a clean exterior that resists mechanical fouling.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance and durability in humid or mildly aggressive environments. It utilizes PT tapered port threads and lacks a magnet, meaning it is optimized purely for actuation rather than proximity sensing.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX475 Is Used
Heavy-Duty Pressing
Applies 5497 N of force at 0.7 MPa to securely seat bearings, bushings, or heavy components into housings without hydraulic fluid.
Large Pallet Diverting
Extends 475 mm to push heavy pallets or workpieces across high-throughput conveyor transfer lines reliably.
Automated Warehousing
Drives robust lifting or pushing mechanisms in automated storage and retrieval systems where high thrust is mandatory.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX475 the Right Cylinder?
Selecting this 100 mm bore provides a substantial jump in thrust over the 80 mm variant, which yields 3518 N at 0.7 MPa. If your application requires less force and a lighter footprint, stepping down is advisable, but for loads needing nearly 5500 N of push, this model is the optimal choice. As a genuine ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 cylinders, matching standard bore, stroke, PT port, and mounting accessory dimensions.
Because the 475 mm stroke is substantial, the unsupported rod length is susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external guide rail or utilize a fully guided cylinder to absorb lateral forces. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not lock or hold the load. If pressure drops, the rod will drift, requiring an external pilot-operated check valve or the SAIL lock variant for secure positioning.
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.
