About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-75S
The AirTAC SAIJ160X650-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 575 to 650 mm. Built to handle heavy loads, it generates 14074 N of push force at 0.7 MPa and utilizes a robust 40 mm SUS304 stainless steel rod. The PT tapered ports and integrated magnet for CMSE or DMSE sensors ensure reliable detection in demanding setups.
This adjustable-stroke design allows precise end-position tuning during commissioning without swapping the cylinder or adding external stops. The rear screw acts purely as a travel stop for deceleration alongside the 50 mm air cushions; it does not hold the load without live air. For position holding without pneumatic pressure, an external rod lock or related SAIL lock variant is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-75S Is Used
Heavy Press Tuning
Dial in the exact 575 to 650 mm end position during machine commissioning to accommodate varying material thicknesses without external stopper hardware.
Product Changeover
Adjust the rear stopper on the fly for different package sizes on a packaging line, leveraging 10053 N of thrust at 0.5 MPa to push heavy loads reliably.
Large Fixture Positioning
Utilize the SUS304 stainless steel rod and 40 mm cushioning to position large manufacturing fixtures, ensuring corrosion resistance and smooth deceleration.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-75S the Right Cylinder?
Choose this 160 mm bore when an application requires significantly more thrust than the 100 mm class (5497 N push at 0.7 MPa), stepping up to 14074 N. The 75 mm adjustment window is ideal for product-size changeovers on a line, enabling variable end-stops without machining new hard stops. Because the stroke extends to 650 mm, the 40 mm SUS304 rod handles substantial side loads, though an external guide remains essential for unsupported lengths to prevent binding.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 160 mm bore, 650 mm nominal stroke, 75 mm adjustment range, PT port threads, and the -S magnet for electronic or reed switches. It supports the reduced SAIJ mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

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 SAIJ160BX650-75S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 13234 N of pull force. At the maximum 1.0 MPa pressure, it achieves a push force of 20053 N.
The rear adjuster screw allows you to trim the effective travel back by up to 75 mm from the 650 mm nominal stroke, creating a 575 to 650 mm usable window. It functions as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
