About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX115-100
The AirTAC SAIJ160X115-100 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical adjuster that allows you to trim the effective stroke by up to 100 mm. This yields a usable travel window of 15 to 115 mm, enabling exact end-position calibration at commissioning without swapping out the unit or adding external stops.
This specific configuration features a SUS304 stainless steel rod (code B) for superior corrosion resistance in harsh environments. It uses PT tapered port threads (G3/4) and omits the magnet option, meaning position sensing via CMSE or DMSE switches is not supported without a different SKU. The extruded aluminum barrel incorporates sensor grooves on three sides, and the cylinder supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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.

Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX115-100 the Right Cylinder?
An adjustable stroke is chosen over a fixed SAI cylinder when a machine requires a variable end-stop for product changeovers or fine-tuning during setup. Because the 115 mm nominal stroke is relatively short, side-loading is less of a concern than on longer strokes, but the 40 mm rod and M36x2 thread handle high mechanical stress well.
For load-holding applications, note that the rear adjuster acts only as a travel stop and the air cushions provide deceleration; neither will maintain a load without live air pressure. If the application requires the load to be held safely in place during a pressure drop, you must integrate an external rod lock, a pilot-operated check valve, or select the SAIL (air-released lock) or BSAI (clamp-lock) variant. This cylinder is dimensionally interchangeable per ISO 15552.
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 SAIJ160BX115-100 FAQ
At the maximum operating pressure of 1.0 MPa, the push force reaches 2050 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 115 mm nominal stroke by up to 100 mm, creating a usable travel window of 15 to 115 mm. It only sets the end position and does not lock the load without live air pressure.
