## 🔌 Function

The ball bearing carries radial and axial loads on a rotating shaft while keeping it precisely aligned within its housing. It reduces friction so the shaft turns freely under load throughout the engine's operating range.

## ⚠️ Common Signs of Failure

-   Whining, rumbling or growling noise that rises and falls with engine or shaft speed
-   Excessive play or shaft wobble when the assembly is checked by hand
-   Vibration or roughness that was not present when the assembly was new
-   Overheating or discolouration at the bearing location
-   Metallic debris, pitting or scoring found on the races or balls during inspection

## 🛠️ Service Notes

-   Work clean — leave the bearing in its wrapping until the moment it goes in, and do not wash the preservative out or blow it dry with compressed air
-   Apply the fitting force only to the ring being fitted, through a tube or drift that bears on that ring alone; force pushed through the balls from one ring to the other dents the raceways and the bearing will be noisy and short-lived from the first run
-   Where the fit calls for it, expand the inner ring with even, controlled heat rather than driving it on, and never heat a bearing with a flame or beyond the temperature given in the workshop manual for your engine
-   Check the shaft and housing seats before fitting — scoring, burrs, corrosion or a worn seat will ruin a new bearing, and fretting marks mean the seat itself needs attention
-   Fit the bearing square and fully home against its shoulder, note which way round any sealed, shielded or marked face must go, and lubricate with the grease or oil specified for the application before it is turned under load
