⚙️ Key Features

  • Genuine Volvo Penta bearing component
  • Factory dimensions and load specification
  • Designed for the original shaft and housing
  • Maintains controlled running clearance
  • Assembly and serial verification required

🔌 Function

Supports and locates the rotating shaft or gear while allowing low-friction movement under load.

⚠️ Common Signs of Failure

  • Rumbling, grinding or whining
  • Heat discolouration
  • Pitting, scoring or metal debris
  • Seal leakage caused by shaft movement

🛠️ 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
