About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-75
The AirTAC SAIJ160X75-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 75 mm stroke that can be dialed back by up to 75 mm, yielding a usable travel window of 0-75 mm for exact end-position tuning during commissioning. Fitted with a SUS420J2 stainless steel rod (option A) and PT tapered ports, it delivers 10053 N of push force at 0.5 MPa and operates at speeds between 30-500 mm/s.
This adjustable stopper lets you fine-tune the retract position on the fly without bolting on external stops or swapping the cylinder. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-75 Is Used
Press Fit Tuning
Dial in the exact 0-75 mm retract position during press-fit operations to compensate for material tolerances without changing the cylinder.
Machine Changeover
Quickly adjust the end-stop when switching product sizes on a production line, using the rear screw to adapt the travel window instantly.
Heavy Material Handling
Leverage the 10053 N push force at 0.5 MPa to move heavy workpieces while using the adjustable stop to set precise resting positions.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-75 the Right Cylinder?
Select this 160 mm bore when a 100 mm bore falls short—stepping up from the 100 mm class (3927 N push at 0.5 MPa) provides the heavy thrust needed for high-force pressing. Choose the SAIJ adjustable variant over a fixed SAI when your machine setup requires variable end-stops or frequent product-size changeovers. To match this cylinder for an ISO 15552 replacement, verify the 160 mm bore, 75 mm stroke, 75 mm adjustment, PT port thread, and the required mounting accessory.
Because the stroke is under 300 mm, side-load stress is moderate, but the robust 40 mm rod and M36x2 thread handle high compressive loads well. If you need position feedback, note that this specific configuration omits the -S magnet, so it cannot host AirTAC CMSE reed or DMSE electronic sensors without modification.

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 SAIJ160AX75-75 FAQ
The rear adjuster acts as an external stop that trims the retract stroke. For this model, the 75 mm nominal stroke can be reduced by up to 75 mm, giving a usable travel window of 0-75 mm for fine-tuning without swapping the cylinder.
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 18095 N.
