About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX165-40S
The AirTAC SAIJ160X165-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 165 mm travel by up to 40 mm. This creates a precise 125-165 mm usable stroke window, perfect for fine-tuning end positions during commissioning without swapping out the hardware. As a 160 mm bore unit, it delivers substantial thrust, pushing with 14074 N at 0.7 MPa.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and ships with a magnet for position sensing. You can mount CMSE reed or DMSE electronic switches directly into the sensor grooves on both sides of the extruded aluminum barrel. The rear screw acts purely as a travel stop to set deceleration limits, so it will not hold a load without live air pressure.

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 SAIJ160BX165-40S Is Used
Heavy Machinery Setup
Fine-tune the retract position of heavy press equipment during initial commissioning, absorbing mechanical variance without machining new stopper blocks.
Product Size Changeover
Quickly adapt a packaging line to different pallet heights by shifting the effective stroke within the 125-165 mm window during production transitions.
Dynamic End-Stop Tuning
Dial in the exact clamping distance for variable workpieces, using the rear adjuster to set the travel limit rather than adding external physical spacers.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX165-40S the Right Cylinder?
Choose this 160 mm bore cylinder when your application requires heavy thrust in the 14000 N range at 0.7 MPa, but you need flexibility on the exact end-of-stroke position. The adjustable stroke is ideal for product changeovers on a line, letting you shift the end stop dynamically rather than installing fixed spacers. To replace an ISO 15552 cylinder, match the 160 mm bore, 165 mm nominal stroke, 40 mm adjustment, G3/4 PT port, and the -S magnet option.
Because the stroke is 165 mm, you should ensure adequate external guiding to prevent excessive side-loading on the large 40 mm rod. Remember that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. If you need true load-holding without continuous air pressure, consider the SAIL locking cylinder or an external rod lock instead of relying on this adjuster.
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 SAIJ160BX165-40S FAQ
The rear adjuster screw allows you to shorten the 165 mm nominal stroke by up to 40 mm, providing a usable travel range of 125 to 165 mm. This stopper only sets the end position and does not lock the load without live air pressure.
