About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX185-20
By turning the rear screw, you can trim the effective travel within a 165-185 mm usable window, providing fine end-position tuning during commissioning without swapping out the physical barrel.
This specific configuration features a SUS304 stainless steel rod (material code B) for superior corrosion resistance, paired with a G3/4 PT tapered port. The extruded aluminum barrel incorporates sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic switches if a magnet is specified later, while the adjustable stopper itself is not a locking device.

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 SAIJ160BX185-20 Is Used
Heavy Press Tuning
Dial in the exact 165 to 185 mm closure position on heavy forming presses during setup, ensuring precise contact without repositioning the entire actuator assembly.
Product Changeover Stops
Quickly adjust the end-stop distance by up to 20 mm on packaging lines when switching between different product sizes, minimizing machine downtime.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for heavy-duty clamping or lifting tasks in washdown or mildly corrosive industrial environments where carbon steel would fail.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX185-20 the Right Cylinder?
The 20 mm rear adjustment window is ideal for product changeovers on a line, allowing you to shift the end-stop dynamically rather than machining external stopper blocks.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 185 mm stroke, 20 mm adjustment range, PT G3/4 port, and SUS304 rod. Although the 185 mm stroke is short, the heavy 40 mm rod diameter handles high side loads well; for any stroke over 300 mm, always add an external guide. Note that the rear adjuster acts only as a travel stop and will not hold the load without live air—if load-holding is required, use an external rod lock or a SAIL/BSAI series cylinder.
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 SAIJ160BX185-20 FAQ
The rear adjusting screw acts as an external stopper that lets you shorten the nominal 185 mm stroke by up to 20 mm, creating a 165 to 185 mm usable travel window. It sets the end position but does not lock the load without continuous air pressure.
