One of the principal failure modes of Babbitt bearings is end loading. This occurs for several reasons:
- Journals are tapered when hot and in service, and when they trip out and run down, the tapered journal rubs against a bearing that was set for non-tapered journal, and wears the end of the bearing, often wiping the Babbitt.
- When sliding pedestals or standards slide and twist instead of sliding straight, or tilt due to broken grout, the bearings are no longer aligned to the journals, and the bearings wear or wipe, depending upon severity.
TRI provided a “Turnkey” Solution to this Problem.
