About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-30S
The AirTAC SAIJ160X260-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 260 mm travel to a precise 230-260 mm window during commissioning. Delivering 14074 N of push force at 0.7 MPa, it handles heavy loads without requiring external stops for end-position tuning. The extruded aluminum barrel features sensor grooves on both sides, and the integrated magnet (-S) supports position detection.
This specific SKU utilizes a SUS304 stainless steel rod (code B) for superior corrosion resistance and features PT tapered port threads. The rear adjuster acts purely as a travel stop to fine-tune the retract position on product changeovers; it is not a locking device and will not hold the load without live air pressure. For position holding, an external SAIL or BSAI lock cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-30S Is Used
Heavy Press Tuning
Dial in the exact 230-260 mm end-stop during machine commissioning to ensure precise pressing force without adding external mechanical stops.
Product Size Changeover
Quickly adjust the retract position on a packaging line when transitioning between different product sizes, saving setup time.
Robotic Material Handling
Leverage the 14074 N push force and SUS304 rod to move heavy pallets, using the CMSE/DMSE compatible magnet for accurate end-of-stroke feedback.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-30S the Right Cylinder?
Select this 160 mm bore cylinder when an application demands high thrust—stepping down to a 125 mm bore yields 8590 N at 0.7 MPa, whereas this model provides 14074 N. The adjustable 230-260 mm travel window is ideal for machinery requiring exact end-position tuning without swapping cylinders. When matching ISO 15552 replacements, verify the 260 mm stroke, 30 mm adjustment range, PT G3/4 port, and the -S magnet.
Because the 260 mm stroke is substantial, the 40 mm rod diameter and M36x2 thread provide robust support, but an external guide is recommended to prevent excessive side-loading on long extensions. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.
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 SAIJ160BX260-30S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. The maximum thrust at 1.0 MPa is 2050 kgf.
The rear adjuster screw allows you to shorten the effective travel from the nominal 260 mm down to 230 mm. This creates a 230-260 mm adjustable window for fine-tuning the end position at commissioning, but it functions as a stop, not a lock.
