About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-100
The AirTAC SAIJ160X155-100 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 155 mm stroke that can be dialed back by up to 100 mm, yielding a precise 55 to 155 mm usable travel window.
This specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes PT tapered port threads. The rear stopper screw allows operators to fine-tune the retract end position during commissioning without swapping hardware. Note that this adjuster acts purely as a travel stop and does not hold the load without continuous 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 SAIJ160BX155-100 Is Used
Heavy-Duty Product Changeover
Quickly adapt a heavy press or clamping station to different material thicknesses by dialing the rear adjuster across the 55-155 mm window, eliminating the need to swap out actuators.
Commissioning End-Position Tuning
Fine-tune the exact retract distance during machine setup to prevent mechanical interference, relying on the rear stopper screw rather than machining custom external spacers.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod to drive high-force tooling in washdown or chemically exposed areas where standard carbon steel rods would degrade.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-100 the Right Cylinder?
The generous 100 mm adjustment range is perfect for machines processing variable product sizes, allowing rapid changeovers by simply turning the rear screw instead of physically replacing the cylinder or adding external stops.
When integrating this actuator, match the exact ISO 15552 replacement parameters: 160 mm bore, 155 mm stroke, up to 100 mm adjustment, PT port threads, and no magnet. Although the SUS304 rod is robust, a 155 mm stroke can still generate leverage; always use an external guide to prevent side-loading damage. For applications requiring true load-holding without live air, a standard SAIJ is insufficient—consider an AirTAC SAIL or BSAI locking cylinder instead.
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 SAIJ160BX155-100 FAQ
The rear adjuster acts as a mechanical stop that shortens the effective travel. For this SAIJ160X155-100 model, you can trim the 155 mm nominal stroke back by up to 100 mm, providing a usable travel window of 55 to 155 mm. It functions as a stop, not a lock, and cannot hold the load without air pressure.
