Hub-and-Flange Casting With Round Hub Flange Part and Central Recessed Profile

Electric motors, hydraulic pump drives, and bearing & transmission assemblies use a round hub flange part with a central recessed profile to register the mating shaft and transmit radial load to the flange mounting face; flange OD, recess depth, and bolt hole pitch together determine the radial runout and mounting accuracy of the assembled unit. Shandong Diheng (through Tai'an Boshen Machinery) casts and machines this iron round hub flange part in Taian with flange OD, recess depth, and bolt hole pitch controlled to your drawing callouts using turning and boring. ISO 9001 and ISO 45001 certification at Diheng's Shandong facility (more than 30,000 m²) governs casting qualification and dimensional records for bearing & transmission, mining, and OEM hub flange applications. Polishing is available as a secondary process. Industries served include automotive, medical equipment, and military. For quoting, include flange OD, recess depth, bolt hole pitch, and iron grade and request a casting and machining quotation from our Taian engineers.
