About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX170-75
The AirTAC SAIJ80X170-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 95-170 mm, allowing you to dial back the 170 mm nominal stroke by up to 75 mm during machine commissioning.
This bore features a 25 mm piston rod with an M20x1.5 thread, paired with a SUS420J2 stainless steel rod material for enhanced durability against minor surface wear. The barrel is an extruded aluminum profile with sensor grooves on both sides, and it uses PT tapered port threads. The rear adjuster acts purely as a travel stop to fine-tune the end position, meaning it does not hold the load without live air pressure.

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 SAIJ80AX170-75 Is Used
Machine Changeovers
Dial in the 95-170 mm travel window during product size transitions without physically replacing the actuator or adding external mechanical stops.
End-Position Tuning
Fine-tune the retract end-position at commissioning using the rear stopper screw to perfect the timing of a 2513 N press operation.
Variable Stroke Assembly
Accommodate multiple part heights on a single conveyor line by adjusting the effective stroke up to 75 mm on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX170-75 the Right Cylinder?
Choose this 80 mm bore when a 50 mm bore (982 N at 0.5 MPa) is insufficient, but a 100 mm bore (3927 N at 0.5 MPa) would be excessive overkill. The 75 mm adjustment range is ideal for product-size changeovers on a line, letting you set variable end-stops without swapping the physical cylinder or bolting on external stops. For load-holding without continuous air pressure, you would need a SAIL or BSAI variant, as the adjuster here is not a lock.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 170 mm nominal stroke, 75 mm adjustment range, PT G3/8 port, and mounting style. SAIJ supports a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the 170 mm stroke is under 300 mm, side-load risks are lower, but the 25 mm rod still handles off-center loads better than smaller diameters.
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 SAIJ80AX170-75 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 170 mm nominal stroke by up to 75 mm. This creates a usable travel window of 95-170 mm to fine-tune end positions without changing the cylinder.
