About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-50
The AirTAC SAIJ160X145-50 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 145 mm stroke that can be dialed back by up to 50 mm, creating a usable travel window between 95 and 145 mm.
This variant features a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet for electronic or reed switch sensing. The rear adjustment mechanism allows for precise end-position tuning during commissioning without requiring cylinder replacement.

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 SAIJ160BX145-50 Is Used
Heavy-Duty Press Tuning
Dial in the exact 95-145 mm press depth during machine setup without swapping out the entire cylinder or adding external mechanical stops.
Product Line Changeover
Quickly adapt the retract distance for varying product sizes on a high-force assembly line, using the 50 mm adjustment to accommodate new dimensions.
Corrosive Environment Assembly
Leverage the SUS304 stainless steel rod for heavy clamping or positioning tasks in wash-down or chemically exposed manufacturing areas.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-50 the Right Cylinder?
Choose this 160 mm bore when your application requires substantial thrust—such as 9425 N pull at 0.5 MPa—and benefits from a variable end-stop. If your force requirements are lower, stepping down to a 125 mm bore yields 5734 N of pull force under the same pressure. Conversely, moving up to a 200 mm bore provides 15080 N of pull force.
The 50 mm adjustment range is perfect for accommodating product changeovers on a line, letting operators fine-tune the retract position on the fly. Because the rear adjuster functions strictly as a travel stop and not a lock, the cylinder cannot hold its load without live air pressure. For dead-end load holding, consider the AirTAC SAIL or BSAI series. When replacing an ISO 15552 cylinder, match the 160 mm bore, 145 mm stroke, 50 mm adjustment, PT G3/4 port, and the correct mounting interface from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, 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 SAIJ160 Adjustable Cylinder SAIJ160BX145-50 FAQ
At the maximum operating pressure of 1.0 MPa, it can generate up to 2050 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from its nominal 145 mm down to as little as 95 mm. It only modifies the retract end position and does not lock the load in place without continuous air pressure.
