Circular Flanged Hub Disc With Splined Coupling Hub and Three Cylindrical Bosses

We manufacture the splined coupling hub with controlled fits for consistent repeat runs. Our Huaian machining center, supported by an IATF 16949–qualified management system, performs gear forming and precision machining for production runs. For your splined coupling hub, we control the key tolerance window, chosen material group, and surface finish requirements as defined inspection checkpoints. Fit class is confirmed against your released requirements during sampling and final release to production. Provide a detailed drawing showing the spline profile and bosses so we can align measurement points and inspection plans. Quotes depend on material and finish; lead times assume agreed tolerances and inspection scope before scheduling.
