About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-50S
The AirTAC SAIJ160X145-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, letting you dial back the travel by up to 50 mm. This yields a usable 95-145 mm stroke window for precise end-position tuning at commissioning without swapping the barrel or adding external stops. It delivers 10053 N pull force at 0.5 MPa, scaling to 18095 N at 0.9 MPa.
This variant features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE and DMSE sensors. It uses PT tapered ports and offers variable air cushions at both ends. The rear adjuster acts purely as a travel stop for deceleration, not a lock, so live air is required to hold the load.

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 SAIJ160BX145-50S Is Used
Machine Changeover
Dial in the 95-145 mm travel window during product size changes without physically replacing the cylinder or repositioning hard stops.
Washdown Automation
Utilize the SUS304 stainless steel rod for corrosion resistance in humid or chemically washed environments requiring robust positioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-50S the Right Cylinder?
The 50 mm adjustment range is ideal for product changeovers on a line, letting you fine-tune the end stop without external hardware. Because the stroke is 145 mm, you are under the 300 mm side-load threshold, but the heavy mass still requires standard guide rails.
To replace an ISO 15552 cylinder, match the 160 mm bore, 145 mm stroke, 50 mm adjuster, PT ports, and the -S magnet. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. For true load-holding without live air, select an SAIL or BSAI cylinder instead of relying on this adjuster.
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 SAIJ160BX145-50S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the 145 mm nominal stroke by up to 50 mm, creating a 95-145 mm usable travel window. It only sets the end position and deceleration; it does not lock the load without live air pressure.
At the maximum operating pressure of 1.0 MPa, it delivers up to 2050 kgf of push force.
