About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX160-75
By turning the external rear stopper screw, you can shorten the effective travel, providing a usable stroke window of 85 to 160mm for precise end-position tuning during commissioning. This eliminates the need to swap out the entire cylinder or bolt on external stops when adapting to new product dimensions.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches, though this specific SKU is supplied without a piston magnet. It supports a speed range of 30-800mm/s and offers the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ80BX160-75 Is Used
Product Changeover
Dial in the exact end-position during line changeovers without replacing the cylinder or adding external mechanical stops.
Stroke Tuning
Fine-tune the 85-160mm travel window at commissioning to perfect the positioning of clamps or presses.
Machine Setup
Use the rear adjuster to set precise retract distances during initial machine assembly and testing.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX160-75 the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end stops or frequent product-size changeovers, offering more flexibility than a fixed-stroke SAI cylinder.
Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series. Because the 160mm stroke is relatively short, side-loading is minimal, but the 25mm rod and M20x1.5 thread provide excellent rigidity. For a true ISO 15552 replacement, match the 80mm bore, 160mm stroke, 75mm adjustment, PT port, and the specified mounting set.
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 SAIJ80BX160-75 FAQ
