About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-50S
The AirTAC SAIJ160X90-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 10053N of push force at 0.5 MPa. Its 90mm nominal stroke can be dialed back by up to 50mm, creating a highly versatile 40-90mm usable travel window for precise end-position tuning during commissioning. This cylinder features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet for position sensing.
It operates at speeds of 30-500mm/s and uses a G3/4 PT tapered port. Unlike fixed-stroke actuators, this model allows you to trim the retract position without swapping the cylinder or adding external stops. The rear adjuster acts strictly 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.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-50S Is Used
Heavy Press Tuning
Fine-tune the 40-90mm retract stop on a heavy press without machining new spacers, ensuring precise clamping force across different material thicknesses.
Product Size Changeover
Quickly adjust the stroke window on packaging lines when transitioning between product sizes, using the rear screw to set new end positions in seconds.
Machine Setup Calibration
Dial in the exact end-of-travel position during initial machine commissioning, absorbing mechanical variances without needing a custom-length cylinder.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-50S the Right Cylinder?
Choose this 160mm bore actuator when an application demands high thrust (10053N push at 0.5 MPa) alongside variable end-stops. If you need less force, stepping down to a 125mm bore yields 6136N, but this SAIJ160X90-50-S is ideal for heavy-duty changeovers. The 50mm adjustment window is perfect for dialing in exact retraction on product-size changes. Since the 90mm stroke is under the 300mm threshold, side-load concerns are minimal, though the robust 40mm rod and M36x2 thread handle substantial loads.
To match this ISO 15552 interchangeable cylinder exactly, specify: 160mm bore, 90mm stroke, 50mm adjustment, PT port thread, SUS420J2 rod (A), and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The integrated magnet works seamlessly with AirTAC CMSE (reed) and DMSE (electronic) switches mounted in the dual sensor grooves.

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 SAIJ160AX90-50S FAQ
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke by up to 50mm. This turns the 90mm nominal stroke into a 40-90mm usable travel window, allowing precise end-position tuning without swapping cylinders.
At 0.5 MPa operating pressure, the SAIJ160X90-50-S provides 10053N of push force and 9425N of pull force. It can reach a maximum push force of 18095N at 0.9 MPa.
