About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-40
The AirTAC SAIJ160X260-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust performance for heavy-duty pneumatics. It features a 260 mm nominal stroke that can be fine-tuned down by up to 40 mm, providing a usable travel window between 220 and 260 mm. Utilizing a PT tapered port thread and a durable SUS304 stainless steel rod, this model is built to withstand demanding environments while maintaining the standard ISO 15552 mounting interface.
In this configuration, the 160 mm bore generates a substantial 18095 N of push force at 0.9 MPa, making it ideal for high-thrust applications. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible positioning of CMSE or DMSE switches, though this specific SKU is supplied without a magnet. The rear adjuster acts purely as a mechanical stop to set the retraction end-point and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-40 Is Used
Heavy Press Tuning
Dial in the exact 220-260 mm end-position during press setup to accommodate varying material thicknesses without changing the cylinder.
Product Changeover
Quickly adjust the retraction stop on a packaging line to handle different carton sizes, leveraging the 40 mm trim range for rapid format changes.
Assembly Station Calibration
Fine-tune the stroke end-point on heavy assembly fixtures to achieve precise mating forces, utilizing the 18095 N thrust capacity safely.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-40 the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires up to 18095 N of push force at 0.9 MPa; stepping down to a 125 mm bore would reduce that output to 11045 N, while moving up to a 200 mm bore offers 28274 N. The adjustable 220-260 mm travel window is perfect for commissioning fine-tuning or accommodating product changeovers without physically swapping the cylinder or adding external stops. For load-holding requirements without continuous air pressure, an external rod lock or a dedicated SAIL cylinder is necessary, as the SAIJ adjuster is strictly a travel stop. Because the total stroke reaches 260 mm, ensure adequate external guiding to prevent excessive side-loading on the rod.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ160BX260-40 FAQ
The 160 mm bore provides a push force of 18095 N and a pull force of 9425 N at 0.9 MPa. The operational speed range for this cylinder is 30-500 mm/s.
The rear mechanical stopper allows you to shorten the 260 mm nominal stroke by up to 40 mm, creating an adjustable travel window of 220 to 260 mm. It functions only as an end-position stop and does not lock the load without air pressure.
