About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-20
The AirTAC SAIJ160X450-20 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster. It provides a 14074N push force at 0.7 MPa and features a 430 to 450 mm usable travel window, letting you dial back the nominal 450 mm stroke by up to 20 mm during commissioning without adding external stops. This 160 mm bore actuator uses a PT tapered port and a durable SUS304 stainless steel rod to handle demanding industrial environments.
The external adjuster acts purely as a travel stop to fine-tune the retract end position and is not a lock, meaning the cylinder cannot hold a load without live air pressure. For position holding, explore SAIL or BSAI variants. This profile cylinder supports speeds of 30-500 mm/s and includes sensor grooves on both sides for CMSE reed or DMSE electronic switches.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-20 Is Used
Heavy Press Fitting
Dial in the exact 430-450 mm end-stop for heavy press fits during machine commissioning without swapping out the entire actuator.
Product Changeover
Quickly adjust the retract position on automated lines when product sizes change, using the rear screw to fine-tune the travel window.
Large Assembly Jigs
Leverage the 14074N push force at 0.7 MPa to move heavy pallets or tooling, relying on the SUS304 rod for corrosion resistance.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-20 the Right Cylinder?
Select this 160 mm bore model when your application requires high thrust, delivering 10053N pull force at 0.5 MPa, and you need precise end-position tuning. If your force requirements are lower, stepping down to a 125 mm bore yields 6136N push at 0.5 MPa, while stepping up to a 200 mm bore provides 15708N push. The adjustable 430-450 mm window is ideal for machine setups requiring variable end stops rather than a fixed SAI stroke.
Because the 450 mm stroke is substantial, the 40 mm diameter SUS304 rod will still experience leverage on long unsupported loads, so an external guide is recommended to prevent side-loading damage. This actuator uses a PT port thread, omits a magnet for sensors, and is dimensionally interchangeable per ISO 15552 mounting interfaces. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

- ✓ 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 SAIJ160BX450-20 FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074N and a pull force of 12621N. At the maximum pressure of 1.0 MPa, the push force reaches 18095N.
The rear adjuster screw lets you shorten the effective travel from the nominal 450 mm down to 430 mm. This creates a 20 mm adjustable window for fine-tuning the end position at commissioning, but the adjuster acts only as a stop and does not lock the load without live air.
