Bearing Cup, 4.8 in OD
SAF-Holland

The Bearing Cup is a precision-housed component that centers and supports wheel bearings within the hub, enabling smooth rotation and minimizing radial play. With a 4.8-inch outer diameter, this cup is chosen to match specific bearing assemblies and hub geometries common in heavy-duty trucks. A high-quality bearing cup contributes to reduced vibration, improved steering stability, and longer bearing life by maintaining consistent preload and alignment under load cycles. Look for proper seating in the hub bore during installation, verify seal contact surfaces are intact, and confirm compatibility with the corresponding bearings and seals. Debris intrusion beneath the cup can cause bearing misalignment or accelerated wear, so cleanliness during servicing is essential. Source One Parts Center offers this bearing cup as a SAF-Holland compatible option.
