The Wheel Hub O-Ring Seal is a circular elastomeric sealing component installed in a groove within the wheel hub assembly to prevent fluid leakage and block contaminants from entering rotating interfaces. It maintains continuous surface contact by deforming elastically under radial compression between mating metal surfaces. This ensures a tight seal under static and dynamic conditions common in high-load wheel systems.Attributes:• Circular cross-section provides uniform radial sealing.• Maintains sealing efficiency under cyclic compression.• Eliminates the need for adhesive or complex retention.Applications: The Wheel Hub O-Ring Seal maintains a secure radial seal within the wheel hub assembly, preventing oil leakage and the entry of mud, water, and particulates into the hub cavity. It deforms under compression between the rotating hub and stationary housing components, protecting internal bearings and shafts from environmental exposure.
