Bearing Cover
Mack

The bearing cover functions as a protective enclosure for a rotating bearing, shielding it from dirt, water, and debris while keeping lubricant contained within the bearing cavity. Its robust construction minimizes contamination ingress and helps maintain proper lubrication film, which reduces wear and promotes a longer service life for the bearing assembly. The cover’s precision fit ensures proper alignment of seals and housings, contributing to quieter operation and better heat management under heavy-use conditions. In installation, the cover is torqued to spec to preserve seal integrity and prevent leaks that could compromise bearing performance. This component is essential in axles, suspensions, and driveline assemblies where resilience and cleanliness directly affect uptime. Regular inspection for seal integrity and fastener torque helps sustain performance. Source One Parts Center.
