About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX160-20S
The AirTAC SAIJ160X160-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 140 to 160 mm, allowing you to dial back the nominal 160 mm stroke by up to 20 mm during machine commissioning. In the 160 mm bore class, it generates 10053 N of pull force at 0.5 MPa, making it suitable for moving heavy industrial loads.
This unit includes a SUS304 stainless steel rod for superior corrosion resistance and is equipped with a magnet for position sensing. The extruded aluminum barrel features sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Fluid supply is routed through PT G3/4 ports, and the integrated air cushions at both ends decelerate the moving mass smoothly.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX160-20S Is Used
Heavy Assembly Presses
Dial in the exact 140 to 160 mm end-stop during press setup to accommodate varying material thicknesses without swapping out the entire actuator.
Product Diverters
Adjust the retract position on the fly during product size changeovers, using the rear stopper to fine-tune the diverting arm clearance.
Large Material Handling
Leverage the 10053 N pull force to shift heavy pallets or structural components while using the SUS304 rod in environments prone to moisture.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX160-20S the Right Cylinder?
Select this 160 mm bore cylinder when an application requires 10053 N of pull force at 0.5 MPa but still needs precise end-position tuning without external stops. The rear adjuster lets you trim the stroke back by up to 20 mm to accommodate product size changes on a line. If your force requirements are lower, stepping down to a 125 mm bore yields 5734 N of pull force at 0.5 MPa, which saves space and air consumption. Conversely, moving up to a 200 mm bore provides 15080 N of pull force at 0.5 MPa for heavier payloads.
Because this is a 160 mm stroke, it does not require external guide rails for side-load support, but always verify the load center of gravity. The rear adjuster and air cushions act strictly as travel stops and deceleration devices, not as locks. The plain SAIJ cylinder will not hold its load without live air pressure. For fail-safe load holding, select the SAIL pneumatic lock series or the BSAI clamp-lock cylinder instead. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits the FB, CA, CB, and CR mounts.

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 SAIJ160BX160-20S FAQ
The maximum operating pressure is 1.0 MPa.
A rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective stroke from the nominal 160 mm down to a minimum of 140 mm. This provides a 140 to 160 mm usable travel window for fine-tuning the end position at commissioning.
