About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-40
The AirTAC SAIJ160X145-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, letting you dial back the 145 mm nominal stroke by up to 40 mm. This creates a precise 105-145 mm usable travel window for fine-tuning end positions during commissioning.
This specific SKU features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The 40 mm diameter rod and M36x2 rod thread handle high side loads well, though long unsupported strokes still require an external guide. It supports speeds of 30-500 mm/s and uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR mounts.

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 SAIJ160BX145-40 Is Used
Variable End-Stop Tuning
Dial in the exact 105 to 145 mm retract position during machine commissioning to perfect product handling without adding external stopper blocks.
Product Size Changeover
Quickly adapt a packaging line to different carton sizes by turning the rear adjuster screw, saving the downtime of physically swapping cylinders.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for reliable, high-force clamping in washdown or chemical processing areas where carbon steel would fail.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-40 the Right Cylinder?
An adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers without swapping cylinders. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, select an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 interchangeable cylinder, specify: 160 mm bore, 145 mm stroke, 40 mm adjustment, PT ports, and no magnet.
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 SAIJ160BX145-40 FAQ
The rear adjuster acts as a mechanical stop that trims the retract travel. For this 145 mm stroke model, the -40 code provides an adjustable usable travel window of 105 to 145 mm, allowing precise end-position tuning without replacing the cylinder.
