## 🔌 Function

Supports a rotating shaft or engine component with controlled friction and clearance.

## ⚠️ Common Signs of Failure

-   Rumbling or roughness develops
-   Excessive play is measured
-   Heat or vibration increases
-   The bearing binds or seizes
-   Metal debris is found

## 🛠️ Service Notes

-   Keep the bearing wrapped until you fit it and work clean — dirt trapped in at assembly is a leading cause of early failure
-   Inspect the shaft and housing seats for wear, scoring and burrs; a new bearing in a worn seat only repeats the failure
-   Press or drive squarely on the race being fitted, using a drift or tube that contacts the ring face fully, so the load never passes through the balls, rollers or bearing surface; never strike the bearing itself
-   Lubricate with the grade specified for that assembly, and where the bearing takes an adjustable preload or endfloat, set it by the workshop manual procedure rather than by feel
-   Renew the adjacent seal whenever a bearing is replaced — access is already open, and a failed seal is often what killed the bearing
-   Volvo Penta's overhaul kits call for 4 or 6 off of this part, the count following the number of cylinders
