About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX350-30
The AirTAC SAIJ80X350-30 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. The integrated rear adjusting screw allows you to fine-tune the effective travel window down from 350mm to a minimum of 320mm, providing precise end-position control without swapping out hardware.
This 80mm bore unit features a SUS304 stainless steel rod (code B) for superior corrosion resistance. Because the 350mm stroke is relatively long, the substantial 25mm rod diameter helps manage side loads, though an external guide is still recommended for unsupported lengths. The extruded aluminum barrel includes sensor grooves on both sides, and the rear stopper acts purely as a travel limit, not a load-holding lock.

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 SAIJ80BX350-30 Is Used
Product Size Changeovers
Quickly dial the retraction point back by up to 30mm during packaging format changes, accommodating different product lengths without replacing the cylinder.
Machine Setup Calibration
Fine-tune the end-of-stroke position during initial commissioning to perfectly align heavy 80mm bore tooling, avoiding the need for machined external stopper blocks.
Variable End-Stop Diverter
Adjust the stroke window between 320mm and 350mm on the fly to reposition a conveyor diverting arm for varying pallet sizes.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX350-30 the Right Cylinder?
The adjustable 320-350mm travel window is ideal for product-size changeovers on a line, allowing operators to dial in the exact retraction point at commissioning rather than machining custom external stops.
For a direct ISO 15552 replacement match, specify the 80mm bore, 350mm stroke, 30mm adjustment, PT tapered port threads, and SUS304 stainless steel rod. Note that this SAIJ variant uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Since the plain cylinder lacks a magnet, it cannot host CMSE or DMSE sensors without modification.

- ✓ 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 SAIJ80BX350-30 FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective stroke from its 350mm nominal length down to 320mm. It only sets the travel end and does not lock the load without live air pressure.
