About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-75
The AirTAC SAIJ160X750-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits an effective travel window of 675 to 750 mm. Built with a 160 mm bore, it delivers a robust 14074 N push force at 0.7 MPa, making it suitable for heavy-duty positioning tasks. The unit features a SUS304 stainless steel rod and PT tapered ports for secure, high-pressure pneumatic connections.
Because the external stopper trims up to 75 mm off the nominal travel, operators can dial in exact end positions during commissioning without swapping out the barrel or adding external mechanical stops. The adjuster functions strictly as a travel stop to set the end-of-stroke deceleration point alongside the built-in air cushions; it is not a locking mechanism and will not hold a load without continuous air pressure. For load-holding requirements, explore the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-75 Is Used
Heavy-Duty Press Tuning
Dial in the exact 675 to 750 mm end position during press commissioning to accommodate varying material thicknesses without external stopper blocks.
Product Changeover Lines
Adjust the retract stopper on the fly when switching conveyor pallet sizes, ensuring precise placement without replacing the entire actuator.
Long-Stroke Assembly Jigs
Utilize the 14074 N push force to move heavy pallets into workstation fixtures, relying on the rear screw for final alignment calibration.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-75 the Right Cylinder?
Select this 160 mm bore unit when an application requires substantial thrust—such as 14074 N at 0.7 MPa—and a variable end-stop. If the project needs less force, stepping down to a 125 mm bore yields 8590 N at 0.5 MPa, whereas moving up to a 200 mm bore provides 21991 N at 0.7 MPa. The adjustable stroke is specifically chosen for machine setups requiring product-size changeovers or fine end-position tuning without hardware modifications.
To replace an ISO 15552 cylinder, match the 160 mm bore, 750 mm stroke, 75 mm adjustment range, PT port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that this unit omits the FB, CA, CB, and CR mounts. Because the stroke is 750 mm, the 40 mm diameter SUS304 rod and M36x2 thread provide high rigidity, but an external guide is strongly recommended to prevent rod sag and side-load damage over this long unsupported travel. The operating speed is 30-500 mm/s.

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 SAIJ160BX750-75 FAQ
At a 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. The maximum thrust is 10053 N at 0.5 MPa.
The rear adjuster acts as a mechanical stop that shortens the effective travel from the 750 mm nominal stroke down to as little as 675 mm. It sets the end position and works with the air cushions to decelerate the load, but it does not lock the piston in place without live air pressure.
