About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-75
The AirTAC SAIJ160X140-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust thrust for heavy-duty operations. It yields 14074N of push force at 0.7 MPa and utilizes a G3/4 port with a 40mm carbon steel rod. The integrated rear stopper allows you to fine-tune the effective travel window anywhere between 65 and 140mm, providing exact end-position calibration without swapping out the entire actuator.
This adjustable capability is ideal for production lines running mixed product sizes, enabling rapid changeovers by simply dialing back the stroke. The extruded aluminum barrel features sensor grooves on both sides, and while this unit uses a standard carbon steel rod, you can specify SUS304 (B) material for corrosive environments. Remember that the rear adjuster functions purely as a travel stop to set deceleration, not as a locking device, so live air is required to maintain the load.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-75 Is Used
Heavy Press Tuning
Dial in the exact 65 to 140mm end-stop during initial commissioning of a high-force press without machining custom spacers.
Product Changeovers
Quickly adjust the rear stroke stopper to accommodate different package sizes on a heavy-duty conveying line.
Assembly Station Setup
Fine-tune the clamping travel window on the fly to prevent overtravel when securing large components.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-75 the Right Cylinder?
Choose this 160mm bore actuator when your application demands high force, such as the 14074N push output at 0.7 MPa, alongside flexible end-positioning. If your setup only requires moderate thrust, stepping down to a 125mm bore provides 8590N at 0.7 MPa, whereas moving up to a 200mm bore offers 21991N. The SAIJ160X140-75 is selected over a fixed-stroke SAI cylinder when you need on-the-fly mechanical adjustments during commissioning or product size changes, eliminating the need for external stops.
Because this model features a 140mm stroke, it does not require external guide rails for side-load support, though the substantial 40mm rod diameter inherently handles greater bending stress than smaller bores. To achieve a true ISO 15552 replacement match, verify the 160mm bore, 140mm stroke, 75mm adjustment range, PT tapered port thread, and your preferred mounting bracket from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). For applications requiring the load to be held mechanically without air pressure, consider the SAIL or BSAI locking cylinder variants instead.

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 SAIJ160X140-75 FAQ
At an operating pressure of 0.7 MPa, this 160mm bore cylinder provides a push force of 14074N and a pull force of 9425N. It can deliver a maximum push force of 18095N at 0.9 MPa.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the nominal 140mm stroke by up to 75mm. This creates a usable travel window of 65 to 140mm, enabling precise end-position tuning without replacing the cylinder.
