About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-20
The AirTAC SAIJ160X475-20 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a usable travel window of 455-475 mm, allowing you to dial in the exact retract end-position during commissioning without adding external stops. It belongs to the 160 mm bore class, delivering a robust 14074N push force at 0.7 MPa and 18095N at 0.9 MPa.
This unit is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a PT tapered port thread. The extruded aluminum barrel incorporates sensor grooves on both sides for direct mounting of switches. Because the 475 mm stroke is long, the M36x2 rod thread and 40 mm rod diameter provide rigidity, but an external guide is still recommended to manage side loads. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-20 Is Used
Machine Setup Changeover
Dial in the retract position within the 455-475 mm window during product size changeovers without swapping out the entire cylinder assembly.
Heavy Material Forming
Leverage the 18095N pull force at 0.9 MPa for deep drawing or pressing tasks, using the rear stop to prevent overtravel and tool damage.
Long-Stroke Alignment
Use the 475 mm travel to push heavy structural components into place, relying on the external guide to handle side loads while fine-tuning the final stop.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-20 the Right Cylinder?
Choose this 160 mm bore if you need heavy thrust that exceeds the 80 mm bore's 3518N push at 0.7 MPa, but do not require the massive 21991N push of the 200 mm version. An adjustable stroke is ideal for machinery requiring fine end-position tuning during product changeover, whereas a fixed SAI cylinder locks you to a single dimension. To replace an ISO 15552 cylinder, match the 475 mm stroke, 20 mm adjustment range, PT G3/4 port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the rear adjuster only sets the travel end; for true load-holding without live air, select a SAIL or BSAI cylinder.
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 SAIJ160BX475-20 FAQ
The rear adjuster allows you to shorten the nominal 475 mm stroke by up to 20 mm, creating a usable travel window of 455-475 mm. It functions as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
At a 0.7 MPa operating pressure, it provides 14074N of push force and 9425N of pull force. At 0.9 MPa, the push force increases to 18095N.
