Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-75
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 90mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-75
The AirTAC SAIJ160X90-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 90 mm stroke by up to 75 mm. This yields a usable travel window of 15 to 90 mm, providing immense flexibility for end-position tuning without swapping out the barrel. Built for heavy-duty tasks, the 160 mm bore delivers 18095 N of push force at 0.9 MPa, while the robust 40 mm SUS304 stainless steel rod handles high side-load stresses with excellent corrosion resistance.
Unlike fixed-stroke SAI units, this adjustable model uses an external rear stopper screw to set the retract end-point precisely during commissioning or product changeover. The extruded aluminum barrel features sensor grooves on both sides for CMSE reed or DMSE electronic switches, and the cylinder supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-75 Is Used
Heavy Press Fit Tuning
Dial in the exact 15-90 mm retract distance for heavy press-fit operations, allowing precise depth control during machine setup and product changeovers.
Multi-Size Forming Line
Adjust the end-stop on the fly to accommodate different material thicknesses on a single forming line, leveraging the 18095 N push force at 0.9 MPa.
Corrosive Environment Stops
Rely on the SUS304 stainless steel rod for adjustable end-position tuning in washdown or corrosive manufacturing settings without degrading the rod surface.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-75 the Right Cylinder?
Choose this 160 mm bore adjustable cylinder when your application requires substantial thrust—stepping down to a 125 mm bore reduces your 0.5 MPa push force to 6136 N, whereas this model provides 10053 N at the same pressure. The SAIJ160X90-75 is selected over a fixed SAI when you need a variable end-stop to accommodate multiple product sizes on the same line without adding external physical stops.
Because the 90 mm nominal stroke is below the 300 mm threshold, external guide requirements are less stringent than on long-stroke units, though the heavy 40 mm rod thread still provides excellent rigidity. For load-holding without continuous air pressure, this cylinder is not a lock; you would need to specify an SAIL (air-released lock) or BSAI (clamp-lock) variant instead. This specific SKU features PT tapered port threads and a SUS304 stainless steel rod for corrosive environments, with no internal magnet specified.

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 SAIJ160BX90-75 FAQ
At an operating pressure of 0.9 MPa, the 160 mm bore generates a push force of 18095 N and a pull force of 9425 N. The maximum push force reaches 2050 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm from the nominal 90 mm, providing an adjustable travel window of 15 to 90 mm. This stopper only sets the end position and does not lock the load without live air pressure.
