About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-75S
The AirTAC SAIJ160X225-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 150 to 225 mm, allowing you to dial back the nominal stroke by up to 75 mm during commissioning. Belonging to the 160 mm bore class, it generates 10053 N of pull force at 0.5 MPa and accommodates operating speeds of 30 to 500 mm/s.
This unit integrates a SUS304 stainless steel rod for superior corrosion resistance and pairs with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches for precise end-of-travel detection.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract distance between 150 and 225 mm during machine commissioning without physically changing the cylinder or adding external stopper blocks.
Product Size Changeover
Quickly adapt automated line tooling to accommodate different product lengths by turning the rear adjuster screw to shift the end-of-stroke position.
Heavy Forming Positioning
Leverage the 10053 N pull force to move heavy jigs into a precise end position, relying on the built-in air cushions to decelerate the load smoothly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-75S the Right Cylinder?
Selecting this adjustable model over a fixed-stroke SAI cylinder eliminates the need to swap components or bolt on external stops when fine-tuning machine end positions. If your application requires less thrust, stepping down to the 125 mm bore yields 5734 N of pull at 0.5 MPa. Conversely, the 200 mm bore offers 15080 N of pull for heavier loads. Remember that the rear adjuster acts strictly as a travel stop, not a load-holding brake; if you need to maintain position without live air pressure, consider an AirTAC SAIL or BSAI cylinder.
When replacing an ISO 15552 unit, match the 160 mm bore, 225 mm stroke, 75 mm adjustment range, PT G3/4 ports, and the -S magnet. Because the 225 mm stroke exceeds 300 mm? No, but for any extended travel, ensure external guides support the load to prevent excessive side-loading on the M36x2 rod thread. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ160BX225-75S FAQ
At an operating pressure of 0.5 MPa, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. The maximum rated thrust is 2050 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 225 mm down to 150 mm. It only sets the travel end and does not lock the load without live air pressure.
