About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-75
The AirTAC SAIJ80X165-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 165 mm travel by up to 75 mm. This creates a highly flexible 90-165 mm usable stroke window, perfect for fine-tuning end positions during commissioning or product changeovers without swapping out the entire actuator.
This model features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads (G3/8). The extruded aluminum barrel includes sensor grooves on both sides for straightforward switch mounting. If you require position feedback, adding a magnet allows the use of AirTAC CMSE reed or DMSE electronic solid-state sensors.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-75 Is Used
Machine Changeover
Quickly adapt the cylinder's end-of-stroke position within the 90-165 mm window when switching a packaging line to a different carton size.
Prototype Positioning
Dial in the exact clamping distance during machine commissioning without machining custom external stopper blocks.
Variable End Stops
Provide adjustable physical endpoints for assembly presses that need to accommodate multiple part heights on the same fixture.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-75 the Right Cylinder?
If you need less force, stepping down to a 63 mm bore yields 1559 N; if you need more, a 100 mm bore provides 3927 N. The generous 75 mm adjustment window on this SKU is ideal for prototyping or lines running multiple product sizes, replacing the need to inventory several fixed-stroke SAI cylinders.
When matching your ISO 15552 replacement, confirm the 80 mm bore, 165 mm stroke, 75 mm adjuster, PT G3/8 port, and SUS420J2 rod. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster acts strictly as a travel stop and the air cushions handle deceleration; neither will hold a load safely without live air. For dead-load holding, consider an external pilot-operated check valve or AirTAC SAIL lock cylinder. Because the 165 mm stroke is relatively short, side-load stress is minimal, but always guide the load externally for optimal seal life.
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 SAIJ80 Adjustable Cylinder SAIJ80AX165-75 FAQ
If operated at 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 165 mm down to as little as 90 mm. This creates a 90-165 mm usable window, letting you set the precise retract end-position at commissioning without changing the cylinder.
