About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-30
The AirTAC SAIJ160X260-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 10053N of push force at 0.5MPa. It provides a usable travel window of 230 to 260mm, allowing precise end-position tuning during commissioning without swapping out the entire actuator. The extruded aluminum barrel features sensor grooves on both sides, though this specific SKU omits the magnet.
Built for demanding environments, this unit utilizes a SUS304 stainless steel rod for superior corrosion resistance and ships with PT tapered port threads. The M36x2 rod thread and 40mm cushion length handle substantial kinetic energy. The rear adjuster acts strictly as a travel stop to set deceleration limits and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-30 Is Used
Heavy Press Tuning
Dial in the exact 230 to 260mm travel window during heavy press commissioning to accommodate material thickness variations without external stops.
Product Size Changeover
Quickly adjust the rear stopper by up to 30mm on automated lines when switching between different product sizes or fixture heights.
Robotic Material Handling
Provides robust 10053N thrust for large robotic grippers, with the SUS304 rod offering excellent corrosion resistance in harsh industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-30 the Right Cylinder?
Select this 160mm bore actuator when an application requires heavy thrust up to 10053N at 0.5MPa but still needs variable end-stops for product changeovers. If you need less force, stepping down to a 125mm bore yields 6136N push force at 0.5MPa. Choose the SAIJ adjustable format over a fixed SAI cylinder when you need on-the-fly stroke trimming at machine setup. Because this is a 260mm stroke, ensure external guides support the load to prevent excessive side-loading on the rod.
For an exact ISO 15552 replacement, match the 160mm bore, 260mm nominal stroke, 30mm adjustment range, PT port threads, and SUS304 rod material. Note that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. If your process requires true load-holding without continuous air pressure, use an external rod lock or select the AirTAC SAIL or BSAI series instead.
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 SAIJ160BX260-30 FAQ
At 0.5MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. At 0.7MPa, the push force increases to 14074N.
The rear adjuster screw lets you shorten the effective travel from the 260mm nominal stroke down to 230mm. This stopper only sets the travel end and deceleration point; it does not lock or hold the load without live air pressure.
