Naldoni e Biondi NBBORSCLM22 is a steel S355J2C blind port in the NBBORSCLM cylinder-parts family. It is a weld-on oil-connection component for hydraulic-cylinder fabrication. The CL section shows a closed-bottom, female-threaded blind bore. B is outside diameter and C overall height. A retains its original catalogue drawing label. It is a fabrication component with a blind bottom, not an open-through connection or an interchangeable P/PL port.
The complete article number appears in the manufacturer table and in the independent supplier's selected manufacturer-article-number field. The selected supplier stock-model row agrees with this exact manufacturer thread, dimensions and mass. The supplier brand field is blank (--), so the listing confirms an observed article designation rather than independent authentication of a supplied Naldoni unit.
No working-pressure, flow-capacity, cylinder-load or welding-procedure rating is assigned from this component table. The nominal thread entry does not by itself establish a sealing interface or compatibility with another connection standard.
The genuine supplier photograph is representative of the listed family and may be shared across sizes or P/PL lengths. The local PDF contains the complete relevant manufacturer page, including the exact article row and section drawing. Photograph proportions do not replace the documented dimensions.
