⚙️ Key Features

• Wide heavy-duty ball-bearing design
• Steel construction for high radial and combined loads
• Cross-referenced across Volvo Group applications
• Bearing only; seals, retainer and housing are separate
• Engine type: Heavy-duty marine/industrial rotating assembly

🔌 Function

Supports the rotating shaft while controlling radial and axial movement with low friction.

⚠️ Common Signs of Failure

• Rumbling or grinding noise
• Heat or grease leakage
• Pitting or roughness when rotated
• Secondary belt, fan or shaft damage from bearing collapse

🛠️ 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
