About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX100-40S
It features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. By turning the external rear stopper, you can fine-tune the effective travel down from the 100mm nominal stroke, creating a precise 60-100mm usable window without adding external stops.
This adjustable capability is ideal for product changeovers and end-position tuning at commissioning. The cylinder includes dual-side sensor grooves compatible with CMSE reed and DMSE electronic switches, thanks to the built-in magnet. Remember that the rear adjuster acts only as a travel stop and deceleration aid alongside the air cushions; it does not hold the load without live air. For true load-holding, consider the SAIL or BSAI series.

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 SAIJ160BX100-40S Is Used
Product Changeover
Dial in the exact end-stop position between production runs, adjusting the usable travel window from 60 to 100mm without physically swapping the cylinder or adding external stopper blocks.
Precision Clamping
Secure heavy workpieces with repeatable precision, utilizing the SUS304 stainless steel rod for corrosion resistance in demanding manufacturing environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX100-40S the Right Cylinder?
Choose this 160mm bore when you need heavy thrust up to 14074N at 0.7 MPa, stepping up from a 125mm bore that provides 8590N. The 40mm adjustment window is perfect for dialing in exact end-of-stroke positions during machine setup or varying product sizes on a line, offering flexibility a fixed-stroke SAI cannot match. When ordering an ISO 15552 replacement, verify the 100mm stroke, 40mm adjustment, PT port thread, and the -S magnet requirement.
Because the 100mm stroke is relatively short for this large bore, side-loading is manageable, but you should still ensure the robust M36x2 rod thread and 40mm rod diameter properly carry any moment loads. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Operating speed is rated for 30-500 mm/s.

- ✓ 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 SAIJ160BX100-40S FAQ
The maximum push force is 18095N at 0.9 MPa.
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke from the 100mm nominal length down to 60mm. This creates a 60-100mm usable travel window for fine-tuning end positions at commissioning without replacing the cylinder.
