This precision-machined wheel-end component provides critical axial and radial support within hub assemblies that bear heavy loads and demanding road conditions. Its primary function is to establish a rigid, concentric interface between bearing races, wheel mounting surfaces, and related hub hardware, helping to maintain proper alignment, reduce runout, and distribute loads evenly under torque and braking forces. By delivering a robust, wear-resistant contact surface, it minimizes bearing wear and contributes to longer service life, lower maintenance costs, and improved vehicle uptime in commercial fleets. The design prioritizes dimensional stability and fatigue resistance, which translates to predictable performance across temperature variations and vibration environments typical of highway and heavy-haul operation. This part is cataloged under a VMRS code that aligns with standard wheel-end service and repair documentation, facilitating accurate diagnostics and parts replacement during maintenance intervals. Within the category context of 42848, it complements other hub and wheel-end components to form a cohesive, serviceable assembly. The provided details emphasize safety and handling precautions, including a Cancer and Reproductive Harm warning, underscoring the importance of appropriate PPE and compliance with environmental health guidelines when handling and machining this component. Use the VMRS reference to coordinate with repair manuals and stocking systems for efficient service planning.
