About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-40
The AirTAC SAIJ160X75-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a substantial 18095N push force at 0.9 MPa, utilizing a robust 40mm rod and G3/4 ports. The integrated rear stopper allows you to dial back the 75mm nominal stroke by up to 40mm, creating a precise 35-75mm usable travel window for heavy-duty commissioning.
This variant features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance. Unlike fixed-stroke SAI units, this model lets you fine-tune the retract end-position during product changeovers without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the adjuster functions strictly as a travel stop, not a load-holding lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-40 Is Used
Heavy Press Fine-Tuning
Dial in the exact 35-75mm retract position during heavy press commissioning without swapping cylinders or fabricating external mechanical stops.
Product Size Changeover
Quickly adjust the end-stop on automated lines when product dimensions change, leveraging the 40mm trim window to accommodate new part heights.
Heavy Machinery Setup
Utilize the 10053N push force at 0.5 MPa for robust actuation in large fixtures, relying on the rear screw to set precise resting positions.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-40 the Right Cylinder?
Select this 160mm bore cylinder when an application demands high thrust—stepping down to a 125mm bore drops the 0.5 MPa push force to 6136N, whereas this 160mm unit provides 10053N. The 40mm adjustment range is ideal for machinery requiring variable end-stops during setup. Because the stroke is 75mm, side-load risks are minimal, but the substantial 40mm rod thread handles high bending stresses well.
For ISO 15552 interchangeability, match the 160mm bore, 75mm stroke, 40mm adjustment, PT tapered ports, and SUS420J2 rod. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that this plain SAIJ does not hold loads without live air; for pilot-operated locking, consider the SAIL or BSAI series.

- ✓ 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 SAIJ160AX75-40 FAQ
It features a rear adjusting screw that acts as a mechanical stopper, allowing you to shorten the effective stroke by up to 40mm. This creates a usable travel window of 35 to 75mm, which is set during commissioning without needing live air to hold the position.
At a 0.5 MPa operating pressure, it provides 10053N of push force and 9425N of pull force. At the maximum 1.0 MPa pressure, it delivers 2050 kgf of thrust.
