About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX75-75S
The AirTAC SAIJ160X75-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 14074N at 0.7 MPa. Because this specific SKU carries a 75 mm adjustment code on a 75 mm nominal stroke, it yields a highly versatile usable travel window of 0 to 75 mm. You can fine-tune the exact extend position at commissioning without swapping out the entire actuator or adding external mechanical stops.
This model features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE or DMSE sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the rear stopper simply acts as a travel end deceleration point—it is not a lock and will not hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX75-75S Is Used
Heavy Press Tuning
Dial in the exact end position for high-force pressing or clamping operations within the 0-75 mm travel window without changing the cylinder.
Product Size Changeover
Quickly adapt machinery to different product heights by adjusting the rear stopper screw on the fly during line setup.
Robotic End Effectors
Provides a robust, corrosion-resistant SUS304 rod actuation point for large-scale industrial automation requiring precise endpoint tuning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX75-75S the Right Cylinder?
Choose this 160 mm bore actuator when an application demands extremely high force, offering 14074N push at 0.7 MPa. If you need less force, stepping down to a 125 mm bore yields 8590N push at 0.7 MPa. The adjustable stroke is selected here over a fixed SAI cylinder to allow product-size changeovers directly on the machine line by simply dialing back the rear screw.
For an exact ISO 15552 replacement, match the 160 mm bore, 75 mm stroke, 75 mm adjustment, PT tapered port threads, and the -S magnet requirement. Since the nominal stroke is 75 mm, side-loading is minimal, but the 40 mm rod and M36x2 thread provide excellent rigidity. Remember that for load-holding without live pressure, you must use a SAIL or BSAI variant instead of relying on the adjuster.
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 SAIJ160BX75-75S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder provides a push force of 14074N and a pull force of 9425N. It can reach a maximum push force of 2050 kgf at 1.0 MPa.
The rear adjuster screw allows you to trim the effective stroke anywhere within a 0 to 75 mm usable travel window. It acts as a mechanical stop to set the end position, but it is not a lock and cannot hold the load without continuous air pressure.
