About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX165-20S
The AirTAC SAIJ160X165-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from the 165 mm nominal stroke to a 145 mm minimum. This creates a 145-165 mm usable window, letting you dial in exact end positions during commissioning without swapping out the cylinder or adding external stops. Delivering a robust 9425 N pull force at 0.5 MPa, it is built for heavy-duty tasks.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread. It comes fully equipped with a magnet for position sensing, working seamlessly with AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel incorporates sensor grooves on both sides, and the cylinder relies on variable air cushions at both ends to decelerate the load smoothly.

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 SAIJ160BX165-20S Is Used
Machine Changeover
Quickly adapt the 145-165 mm travel window during product size transitions on a production line, using the rear stopper to set new end positions rapidly.
Corrosive Environments
The SUS304 stainless steel rod makes this -S variant suitable for packaging or food processing areas where standard carbon steel rods might degrade.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX165-20S the Right Cylinder?
Choose this 160 mm bore when you need substantially more force than the 125 mm bore provides (5734 N pull at 0.5 MPa), but do not require the massive 15080 N pull of the 200 mm version. The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers on a line. Because the nominal stroke is 165 mm, an external guide is recommended to manage side loads and prevent rod deflection.
When specifying an ISO 15552 replacement match, verify the 160 mm bore, 165 mm stroke, 20 mm adjustment range, PT port thread, and the -S magnet. Remember that the rear adjuster is a travel stop, not a locking mechanism. It will not hold the load without live air pressure; for true fail-safe load holding, consider the AirTAC SAIL or BSAI series, or use an external pilot-operated check valve. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ160BX165-20S FAQ
At the maximum 1.0 MPa pressure, the push force reaches 18095 N.
The rear adjuster acts as a mechanical stop that lets you shorten the 165 mm nominal stroke by up to 20 mm, providing a usable travel window of 145-165 mm. It only sets the end position and does not lock the load without live air pressure.
