About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-10
The AirTAC SAIJ160X280-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 18095N at 0.9 MPa. It features a robust 40mm SUS304 stainless steel rod (code B) and a PT tapered G3/4 port. By turning the rear stopper screw, you achieve a precise 270-280mm usable travel window for exact end-position tuning.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops during machine commissioning. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-10 Is Used
Heavy Press Tuning
Dial in the exact 270-280mm end position during heavy press commissioning without changing the cylinder.
Product Changeover
Adjust the retract stop on the fly to accommodate varying product sizes moving down a conveyor line.
Machine Setup
Fine-tune the end-of-stroke position during initial machine setup to prevent mechanical interference.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-10 the Right Cylinder?
Choose this 160mm bore when a 125mm cylinder (providing 11045N push at 0.9 MPa) lacks the necessary force, but a 200mm bore is physically too large. The 10mm adjustment window is ideal for fine-tuning the retract end during product changeovers rather than using a fixed-stroke SAI cylinder. For load-holding without continuous air supply, integrate an external rod lock or select an AirTAC SAIL or BSAI model.
To match this ISO 15552 interchangeable cylinder, specify: 160mm bore, 280mm stroke, 10mm adjustment, PT G3/4 port, SUS304 rod material, and no magnet. Because the 280mm stroke is substantial, ensure external guiding is used to prevent excessive side-loading on the 40mm 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 SAIJ160BX280-10 FAQ
At 0.9 MPa operating pressure, this 160mm bore cylinder provides a push force of 18095N and a pull force of 9425N. Its maximum allowable operating pressure is 1.0 MPa.
The rear adjuster screw lets you trim the effective stroke within a 270-280mm window. It acts as a mechanical stop to fine-tune the end position, but it is not a lock and cannot hold the load without live air pressure.
