About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-30S
The AirTAC SAIJ160X475-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a robust 18095N push force at 0.9 MPa, making it suitable for heavy-duty operations. The integrated -30 mm adjustment screw allows you to fine-tune the effective travel down to 445 mm, creating a 445-475 mm usable window without needing external stops.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. You can mount AirTAC CMSE reed or DMSE electronic sensors directly into the dual side sensor grooves. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions while omitting FB, CA, CB, and CR bracket options in favor of Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-30S Is Used
Heavy Press Tuning
Dial in the exact 445 to 475 mm end-position during heavy press commissioning to accommodate varying material thicknesses without swapping hardware.
Product Changeover
Adjust the rear stopper on the fly for different pallet sizes on a conveyor line, utilizing the 30 mm travel window to avoid repositioning the entire cylinder.
Large Assembly Setups
Leverage the 10053N push force at 0.5 MPa to move heavy assemblies while fine-tuning the final clamping position to precise mechanical tolerances.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-30S the Right Cylinder?
Choose this 160 mm bore when an 80 mm cylinder lacks thrust, as stepping up from the 80 mm bore increases your 0.5 MPa push force from 2513N to 10053N. The adjustable stroke is selected over a fixed SAI cylinder when you need variable end-stops for product changeovers or precise end-position tuning at commissioning. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for dead-air load holding, consider an AirTAC SAIL or BSAI cylinder.
Because this model has a 475 mm stroke, the M36x2 rod and 40 mm cushion length must manage significant kinetic energy. Even with a large 40 mm rod diameter to handle side loads, an external guide is recommended to prevent rod binding over this long travel distance. This configuration includes a PT tapered port, a -S magnet, and the 30 mm adjustment range.
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 SAIJ160BX475-30S FAQ
At 0.9 MPa, this 160 mm bore cylinder provides an 18095N push force and a 9425N pull force at 0.5 MPa. The maximum rated force is 2050 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 475 mm nominal stroke by up to 30 mm, resulting in a 445-475 mm usable travel window. It is a stop, not a lock, and requires live air to hold the load.
