Flanged Metal Connecting Sleeve

Flanged mounting hubs with stepped internal bores provide rigid alignment for rotating shafts or fluid interfaces in mechanical assemblies. The circular base features a pattern of through-holes for bolting to equipment panels, while the extended cylindrical body offers precise locating surfaces for bearings, seals, or coupling elements.

Manufacturing focuses on maintaining strict concentricity between the internal bore and the external flange OD, as well as perpendicularity of the mounting face to the central axis. Critical dimensions such as the shoulder diameter and hole position tolerances are verified using CMM inspection to ensure interference fits remain consistent across batches. Surface finish on sealing or bearing contact areas is controlled to minimize wear and prevent leakage paths.

Leveraging ISO 9001 certified facilities equipped with CNC turning centers and multi-axis machining capabilities, we support production in carbon steel, stainless steel, aluminum, and alloy steels. Secondary operations including heat treatment and surface plating can be integrated to meet specific hardness or corrosion resistance requirements.
