Carbon Steel Coupling with Flanged Hub Splined Bore and Machined Mounting Faces

We produce this flanged hub with splined bore to maintain aligned interfaces in assembly. You can set major diameter range, critical tolerance range, and surface texture so the part tracks your requirements through each operation. Each flanged hub splined bore is controlled against your defined checkpoints, supported by a dimensioned drawing that fixes spline data and flange interfaces. Our Huai'an/Jiangsu facility (IATF 16949, ISO 9001) focuses on precision mechanical manufacturing. The production site covers roughly 15,000 m². Applications cover automotive, medical equipment, and automation. Pricing and lead time reflect batch size, tolerance band, and inspection scope.
