About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX170-40
The AirTAC SAIJ80X170-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 130-170 mm usable travel window, allowing you to dial back the nominal 170 mm stroke by up to 40 mm during commissioning.
The piston rod is built from SUS304 stainless steel (code B) for superior corrosion resistance, while the PT tapered port threads match the standard G3/8 air connection. It carries variable air cushions at both ends to decelerate the load, but the rear stopper is strictly a travel adjuster, not a lock. For position holding without live air, consider the SAIL or BSAI series instead.

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 SAIJ80BX170-40 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance from 130 to 170 mm during machine setup to accommodate varying material thicknesses without external stop blocks.
Product Changeover
Rapidly adjust the stroke window on packaging or handling lines when switching product sizes, minimizing downtime and avoiding cylinder swaps.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for high thrust applications in washdown or corrosive settings where carbon steel rods would fail.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX170-40 the Right Cylinder?
The 40 mm adjustment range is ideal for product changeovers on a line, letting you fine-tune the retract end-position without swapping the cylinder or adding external stops. The robust 25 mm rod and M20x1.5 thread handle high side loads, though strokes of 300 mm or more require an external guide (this 170 mm stroke is well within standard limits).
This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It is dimensionally interchangeable with ISO 15552 cylinders. To match this exact configuration, specify: 80 mm bore, 170 mm stroke, 40 mm adjustment, PT G3/8 port, SUS304 rod, no magnet.
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 SAIJ80BX170-40 FAQ
At 0.9 MPa, the push force increases to 4523 N, with a maximum operating pressure of 1.0 MPa yielding 513 kgf.
The rear adjuster screw lets you shorten the effective travel from the nominal 170 mm down to 130 mm, creating a 40 mm adjustable window. It acts as a physical stop to set the end position, but it does not lock the load without continuous air pressure.
