Bearing Cover
Mack

This bearing cover provides a protective seal and shielding for bearing assemblies in axles or other rotating components. Its design helps contain lubrication, reduce dirt intrusion, and guard against moisture exposure that can accelerate wear. Proper fitment minimizes axial and radial play, contributing to smoother rotation, quieter operation, and longer bearing life under heavy-duty service. The cover’s material selection is intended for durability in challenging environments where vibrations and temperature fluctuations are common. Routine inspection ensures the cover remains intact and seals properly, preventing lubricant leaks and contamination. Source One Parts Center.
