Bearing Cup, 146.97 mm Outer Diameter
SAF-Holland

Bearing cup provides the inner race support and seating surface for the corresponding wheel bearings, maintaining concentricity and axial alignment within the hub assembly. The 146.97 mm outer diameter sizing aligns with specific hub and axle configurations common in heavier trucks, contributing to reliable bearing preload and even race loading. A well-fitted cup reduces micro-motions that can accelerate wear and noise, while helping to maintain seal integrity and lubrication effectiveness. Proper seating and torque are essential to avoid leakage paths and ensure long service life under heavy load and environmental exposure. Inspect surrounding components for wear and corrosion during service to preserve overall hub performance. Source One Parts Center recommends verifying fit and compatibility.
