9707510900 Rear Wheel Inner Bearing is a tapered roller bearing installed inside the rear wheel hub of HFC6782 bus. It bears radial load and axial thrust generated during vehicle running, supporting smooth rotation of wheel hub around the axle spindle. This aftermarket replacement bearing resolves wheel humming noise, loose hub play and hot hub issues caused by roller surface pitting, cage fracture and clearance out of tolerance on worn bearings. Reliable hub support maintains stable wheel running track and prevents wheel lock or detachment risk for passenger buses operating on urban and intercity passenger routes.
Product Advantages Made of high-quality chrome bearing steel with precise heat treatment for high hardness and contact fatigue resistance. Separable tapered roller structure allows independent assembly and preload adjustment. Optimized roller contact line reduces friction heat under heavy load. Every bearing undergoes dimensional inspection, noise test and clearance screening before shipment, OEM specification for direct fit during hub overhaul.
