About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-20S
The AirTAC SAIJ160X475-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 455 to 475 mm usable travel window, allowing you to dial in the exact retract position during commissioning without adding external stops. Built to deliver 14074 N of push force at 0.7 MPa, it handles heavy loads with precision.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE and DMSE sensors. The PT tapered ports are G3/4, and the extruded aluminum barrel integrates sensor grooves on both sides. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-20S Is Used
Heavy Press Tuning
Dial in the exact 455 to 475 mm retract position during machine setup to accommodate varying material thicknesses in a heavy press operation.
Product Changeover
Quickly adjust the end stop on a packaging line to handle different pallet sizes without physically swapping out the entire pneumatic cylinder.
Large Assembly Fixtures
Leverage the 14074 N push force at 0.7 MPa to move heavy components into place, fine-tuning the final seating position via the rear screw.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-20S the Right Cylinder?
Select this 160 mm bore cylinder when an application requires substantial thrust, such as 14074 N push at 0.7 MPa, alongside fine-tuneable end positioning. If you need less force, stepping down to a 125 mm bore yields 8590 N push at 0.7 MPa. The adjustable stroke is ideal for product changeovers, whereas a fixed SAI cylinder suits static end stops. For load-holding without live air, consider a SAIL or BSAI cylinder instead of relying on this adjuster.
Because the 475 mm stroke is long, the 40 mm SUS304 rod and M36x2 thread provide robust support, but an external guide is recommended to manage side loads. This model is dimensionally interchangeable with ISO 15552 cylinders and uses the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160BX475-20S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw allows you to shorten the nominal 475 mm stroke by up to 20 mm, creating a 455 to 475 mm travel window. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
