Cast Iron Pulley with Spoked Pulley Wheel and Central Hub Polygonal Bore Collar

Hub bore profile, spoke pitch circle diameter, and belt groove dimensions are the governing callouts for a spoked pulley wheel; if the polygonal hub bore deviates from the mating shaft profile, the pulley slips under torque rather than transmitting belt load. Shandong Diheng (through Tai'an Boshen Machinery) casts and machines this iron spoked pulley wheel with central hub polygonal bore collar in Taian, with bore profile, spoke PCD, and groove dimensions produced to your drawing tolerances using turning and boring. ISO 9001 and ISO 45001 certification at Diheng's Shandong facility (around 30,000 m²) governs casting qualification and dimensional quality records for agricultural machinery, bearing & transmission, mining, and OEM pulley wheel applications. Polishing and shot blast are available in-house, supporting automotive, medical equipment, and military projects. For quoting, include bore profile, spoke PCD, groove dimensions, and iron grade so we can prepare a casting and machining quotation from our Taian office.
