About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-30
The AirTAC SAIJ160X90-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 90 mm stroke that can be dialed back by up to 30 mm, yielding a 60-90 mm usable travel window for precise end-position tuning during commissioning. The 160 mm bore generates 10053 N of push force and 9425 N of pull force at 0.5 MPa, making it suited for heavy-duty positioning tasks.
This variant uses a SUS304 stainless steel piston rod (option B) for superior corrosion resistance. It features PT tapered port threads (G3/4) and operates at speeds of 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, allowing for the direct mounting of CMSE reed or DMSE electronic sensors if position feedback is later required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-30 Is Used
Machine Changeover Setup
Dial in the exact retracted position within the 60-90 mm window during product size transitions, eliminating the need to swap out the entire cylinder or bolt on external physical stops.
Heavy-Duty Positioning
Leverage the 10053 N push force at 0.5 MPa to move heavy jigs or platens into a precise end-stop location, using the rear adjuster to fine-tune the final resting coordinates.
Commissioning Calibration
Safely trim the effective stroke back by up to 30 mm during initial machine commissioning to prevent mechanical interference, ensuring the cylinder hits the exact desired endpoint.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-30 the Right Cylinder?
Choose this 160 mm bore adjustable-stroke cylinder when your application demands high thrust (10053 N push at 0.5 MPa) alongside variable end-stop positioning without adding external stops. If your force requirements are lower, stepping down to a 125 mm bore yields 6136 N of push force at 0.5 MPa, which may offer a more compact and lighter solution. Conversely, if you need maximum thrust, moving up to a 200 mm bore provides 15708 N at the same pressure.
The adjustable stroke is ideal for machine setups requiring frequent product changeovers or fine-tuning the retracted position. Remember that the rear adjuster functions strictly as a travel stop and does not lock the load; if you need true load-holding without live air pressure, consider the SAIL or BSAI series. For ISO 15552 replacement matching, ensure you specify the 160 mm bore, 90 mm stroke, 30 mm adjustment, PT G3/4 port, and the SUS304 rod material. Because the 90 mm stroke is relatively short, side-loading is minimal, but standard rod alignment practices should still be followed.

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 SAIJ160BX90-30 FAQ
At a standard 0.5 MPa operating pressure, this 160 mm bore cylinder generates 10053 N of push force and 9425 N of pull force. At the maximum rated pressure of 1.0 MPa, it can deliver up to 2050 kgf.
The rear adjuster acts as an external mechanical stop that lets you shorten the effective stroke from the nominal 90 mm down to 60 mm, creating a 60-90 mm usable travel window. It only sets the travel end and does not hold the load without live air pressure.
