Naldoni e Biondi NBBORSM2015 is a weld-on hydraulic cylinder port in the NBBORSM family. Its exact article number appears in the manufacturer catalogue and in an independent supplier's selected product listing. The part is made from S355J2C steel and has a female M20 × 1.5 metric thread.
The port provides a threaded oil connection for cylinder fabrication. It is a component for welding into the assembly, not a complete hydraulic cylinder. The manufacturer section drawing identifies F as the thread, B as the outside diameter and C as the port height. No working-pressure, welding-procedure or complete-cylinder load rating is assigned from this parts table.
The manufacturer table specifies outer diameter B = 30 mm; the supplier title and technical table state 28 mm for the same article. The supplied dimensional revision is not established. Outer diameter is retained as a documentation reference and is not a numeric filter.
The local technical reference contains the complete relevant original manufacturer page, including the exact article row, sectional drawing and material statement. The genuine supplier photograph is representative of this port family; it is shared across multiple sizes and is not dimensional verification.
