About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-10
The AirTAC SAIJ160X260-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust thrust for heavy machinery. It yields a 10053N push force at 0.5 MPa and up to 18095N at 0.9 MPa. By integrating a 10mm adjustment mechanism at the retract end, this model provides a usable travel window of 250-260mm, enabling precise end-position tuning without swapping the unit.
Built with a SUS304 stainless steel rod for superior corrosion resistance, it features PT tapered port threads (G3/4) and dual-sided sensor grooves on the extruded aluminum barrel. The rear adjuster acts purely as a mechanical stop to dial in the stroke during commissioning; it does not lock the load without live air pressure, so applications requiring true load-holding should utilize an external rod lock or the related BSAI clamp-lock series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-10 Is Used
Press Tonnage Setup
Dial in the exact 250-260mm retract distance during heavy press commissioning to accommodate varying material thicknesses without external stop blocks.
Heavy Fixture Alignment
Fine-tune the end-stop position on large machining fixtures to adapt to different part dimensions quickly and accurately on the factory floor.
Material Forming Changeover
Adjust the stroke window on product lines during size changeovers, ensuring precise forming end-positioning without replacing the entire cylinder assembly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-10 the Right Cylinder?
Choose this 160mm bore when the 100mm class (providing 7068N push at 0.9 MPa) is insufficient for your heavy-duty cycle, but a massive 200mm bore is mechanically excessive. The 10mm adjustable window is ideal for fine-tuning the retract end-stop during product changeovers, avoiding the need to bolt on external stops or replace a fixed-stroke SAI cylinder. For a 260mm stroke, the M36x2 rod thread handles high axial loads, but an external guide is recommended to prevent side-load wear on the piston. To match this ISO 15552 footprint exactly, specify the 160mm bore, 260mm stroke, PT ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting set, and no magnet.
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 SAIJ160BX260-10 FAQ
At 0.9 MPa operating pressure, this 160mm bore cylinder generates a push force of 18095N and a pull force of 9425N. At 0.5 MPa, it provides 10053N of push force.
The rear adjuster screw allows you to shorten the effective stroke by up to 10mm, creating a usable travel window between 250mm and 260mm. This mechanical stop fine-tunes the end position but does not hold the load without live air pressure.
