Bearing Cup, 5.5115 in OD
SAF-Holland

Bearing Cup provides a precise radial seat for wheel bearings, supporting load transfer from the hub to the axle assembly with minimal play. With an outside diameter of 5.5115 inches, this cup is machined for a tight slip fit and smooth inner races, reducing binding and wear during operation. The design helps maintain accurate bearing preload, which translates into longer bearing life and steadier wheel performance under heavy loads. Materials and surfaces are finished to resist corrosion and accommodate lubrication in standard hub configurations. Inspect for signs of pitting, spalling, or seal damage during routine maintenance. Proper seating and alignment are essential for preventing heat build‑up and noise that can affect handling. When replacing, ensure compatibility with the corresponding bearing set and hub geometry.
