About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX135-30
The AirTAC SAIJ160X135-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 135 mm nominal stroke that can be fine-tuned backward by up to 30 mm, giving an effective usable travel window of 105-135 mm.
This specific configuration includes a SUS304 stainless steel piston rod for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel integrates sensor grooves on both sides for direct mounting of position switches. While the rear stopper screw allows precise end-position tuning during commissioning without adding external stops, it acts only as a travel limiter and does not hold the load without live air pressure.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 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 SAIJ160 Adjustable Cylinder SAIJ160BX135-30 Is Used
Machine Changeover
Dial in the 105-135 mm stroke window during product size transitions to set new end positions without physically replacing the cylinder or adding external shims.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX135-30 the Right Cylinder?
Choose this 160 mm bore when an application requires substantially more force than the 100 mm bore (which provides 7068 N at 0.9 MPa) but less than the massive 200 mm class. The adjustable 105-135 mm window is ideal for product changeovers or fine-tuning a machine setup where a fixed-stroke SAI cylinder would require shimming or swapping. For any load-holding requirements without continuous air pressure, this cylinder is insufficient; the rear adjuster is a stop, not a lock, so you should look to the SAIL or BSAI series instead. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with standard ISO mounting interfaces and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ160 Adjustable Cylinder SAIJ160BX135-30 FAQ
It features a rear adjusting screw that acts as a mechanical stopper, allowing you to shorten the effective stroke from 135 mm down to 105 mm. This provides a 30 mm tuning window for precise end-position setting during commissioning.
At 0.9 MPa, the push force increases to 18095 N.
