About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX350-40
The AirTAC SAIJ80X350-40 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a usable travel window of 310 to 350 mm, allowing you to dial back the nominal 350 mm stroke by up to 40 mm during commissioning.
This unit incorporates a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. With a 25 mm rod diameter and M20x1.5 thread, it offers robust resistance to side loads, though the 350 mm length still necessitates an external guide for optimal performance.

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 SAIJ80BX350-40 Is Used
Machine Setup Calibration
Perfect for dialing in the exact retract position during initial machine commissioning, using the 40 mm adjustment window to set precise endpoints without machining custom spacers.
Product Size Changeover
Ideal for packaging lines handling varying package depths, allowing operators to quickly shorten the stroke from 350 mm down to 310 mm to accommodate different product sizes on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX350-40 the Right Cylinder?
Select this 80 mm bore cylinder when an application requires substantial thrust combined with variable end-stop positioning. The adjustable stroke mechanism is ideal for product changeovers, letting you fine-tune the retract position without swapping hardware or adding external stops.
Because the 350 mm stroke is substantial, always use an external guide to prevent rod damage from side-loading. The rear adjuster acts strictly as a travel stop to set deceleration endpoints and cannot hold a load without live air pressure. For true load-holding without continuous air supply, consider the AirTAC SAIL or BSAI series. This model uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ80BX350-40 FAQ
At the maximum pressure of 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster screw allows you to mechanically shorten the effective stroke from its nominal 350 mm down to a minimum of 310 mm. This stopper fine-tunes the end position but does not lock the load; live air pressure is still required to hold position.
