About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX150-20
The AirTAC SAIJ160X150-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from a 150 mm nominal stroke to a 130 mm minimum. This creates a highly versatile 130-150 mm usable window for precise end-position tuning during commissioning. The barrel is machined from extruded aluminum and includes sensor grooves on both sides for flexible switch placement.
This specific SKU is configured with a SUS304 stainless steel rod (material code B) for superior corrosion resistance in harsh environments. It utilizes PT tapered port threads and operates without a magnet. The rear adjuster acts purely as a mechanical stop to set the retract end position; it does not lock or hold the load without live air pressure. For position holding without continuous air, an external pilot-operated check valve or a related SAIL lock cylinder is required.

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 SAIJ160BX150-20 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance within the 130-150 mm window to accommodate slight variations in part dimensions without repositioning the entire cylinder assembly.
Machine Changeover
Quickly adjust the stroke end position during product size changeovers on a packaging or handling line, reducing downtime and eliminating the need for custom spacer shims.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX150-20 the Right Cylinder?
Choose this adjustable-stroke model when a fixed 150 mm SAI cylinder cannot provide the exact end-stop precision your application demands. The 20 mm adjustment window is ideal for accommodating product size changes on a line without physically swapping the cylinder or adding external stopper blocks. If your application requires less force, stepping down to a 125 mm bore yields 5734 N of pull at 0.5 MPa, whereas moving up to a 200 mm bore provides 15080 N of pull.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 150 mm stroke, PT port threads, and the 20 mm adjustment requirement. Because the nominal stroke is 150 mm, side-loading is less of a concern than on longer strokes, but the 40 mm rod diameter and M36x2 thread provide excellent rigidity and side-load capacity. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR mounts found on some other profiles.
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 SAIJ160BX150-20 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 2050 kgf of push force.
The rear adjuster screw lets you shorten the nominal 150 mm stroke by up to 20 mm, creating a usable travel window of 130 to 150 mm. It functions as a mechanical stop to fine-tune the retract end position and does not hold the load without live air pressure.
