🔌 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
