About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-75S
The AirTAC SAIJ160X475-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 400 to 475 mm. Built for heavy-duty tasks, it delivers a robust 18095 N push force at 0.9 MPa. The integrated -S magnet enables precise position detection using AirTAC CMSE reed or DMSE electronic solid-state sensors housed within the dual-side sensor grooves.
This model features a SUS304 stainless steel rod (code B) for superior corrosion resistance and carries a substantial M36x2 rod thread. The rear stopper mechanism allows technicians to fine-tune the retract end position during commissioning without swapping out the entire actuator or adding external stops. It operates efficiently at speeds of 30-500 mm/s and utilizes PT tapered port threads for secure pneumatic connections.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-75S Is Used
Heavy Machinery Changeover
Dial in the 400-475 mm travel window during equipment retooling to accommodate different large product sizes without physically replacing the actuator.
Precision Positioning Stops
Use the rear adjuster to set exact retract endpoints for heavy 18095 N push applications, allowing fine-tuning of the final resting position at commissioning.
Automated Assembly Calibration
Leverage the SUS304 rod and integrated CMSE/DMSE sensor magnet to verify stroke endpoints while trimming up to 75 mm off the nominal stroke to perfect part seating.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-75S the Right Cylinder?
Selecting this 160 mm bore actuator makes sense when your application requires substantial pull force, rated at 9425 N at 0.5 MPa, alongside variable end-stop positioning. If your setup only needs moderate thrust, stepping down to a 125 mm bore yields 5734 N pull at 0.5 MPa, whereas moving up to a 200 mm bore provides 15080 N pull at 0.5 MPa for extreme loads. The adjustable stroke is ideal for product-size changeovers on a line, offering flexibility that a fixed-stroke SAI cylinder cannot match.
Because this unit features a 475 mm stroke, the 40 mm rod diameter and M36x2 thread still require an external guide to handle potential side-loading on long unsupported extensions. The rear adjuster acts strictly as a travel stop to set deceleration and end position, not as a locking device; it will not hold the load without live air pressure. For dead-load holding, consider an AirTAC SAIL or BSAI cylinder. This model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options.
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 SAIJ160BX475-75S FAQ
At an operating pressure of 0.9 MPa, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 14074 N. The maximum theoretical force at 1.0 MPa is 2050 kgf.
The rear external screw acts as a mechanical stopper, allowing you to shorten the effective travel from the nominal 475 mm down to 400 mm. It sets the end position but does not lock the load without continuous air pressure.
