About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-50
The AirTAC SAIJ160X600-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel by up to 50 mm. This yields a usable stroke window of 550 to 600 mm, letting you dial in the exact retract end-position during commissioning without swapping out the unit. It delivers 10053 N of push force at 0.5 MPa, placing it firmly in the heavy-duty class for high-load automation.
This variant uses a SUS420J2 stainless steel rod for superior corrosion resistance and pairs with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for easy switch placement. Remember that the rear adjuster acts purely as a mechanical stop to set the travel end; it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-50 Is Used
Heavy Machinery Setup
Fine-tune the 550-600 mm retract stop during heavy equipment assembly to compensate for mechanical tolerances without machining custom spacers.
Product Changeover
Adjust the rear stopper up to 50 mm to accommodate different pallet sizes on a heavy-duty transfer line, minimizing downtime between production runs.
Press Positioning
Dial in the exact end-of-stroke position on a 10053 N press operation, ensuring precise contact depth without reprogramming the machine logic.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-50 the Right Cylinder?
Choose this 160 mm bore when you need substantial thrust (10053 N push at 0.5 MPa) and on-the-fly end-position tuning for a 600 mm stroke. If your application requires less force, stepping down to a 125 mm bore yields 6136 N of push thrust at 0.5 MPa. Conversely, moving up to a 200 mm bore provides 15708 N. The 50 mm adjustment window is perfect for product changeovers where the retract distance varies slightly, saving you from installing external stops or buying a different fixed-stroke SAI cylinder.
Because the 600 mm stroke is long, the 40 mm diameter rod and M36x2 thread will still experience leverage forces under heavy side-loads; an external guide rail is highly recommended to prevent binding. For applications that must hold a load in place without continuous air pressure, this cylinder is not suitable—look instead to an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder. This SAIJ model is dimensionally interchangeable per ISO 15552, uses a PT G3/4 port, and omits the FB, CA, CB, and CR mounting styles found on some other variants.

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 SAIJ160AX600-50 FAQ
The rear adjuster screw lets you shorten the nominal 600 mm stroke by up to 50 mm, providing a usable travel window of 550 to 600 mm. This stopper sets the end position but does not lock or hold the load without live air pressure.
At 0.5 MPa operating pressure, it provides 10053 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 2050 kgf.
