This deep-groove ball bearing supports a rotating shaft within a housing, handling both radial and moderate axial loads. It is a 6005-series bearing with rubber seals on both sides, which retain grease and exclude contaminants, and a C3 internal clearance that allows for thermal expansion during operation. The bearing is pressed onto the shaft and seated in the housing bore; the seals ride on the inner ring to maintain a closed lubrication path. A worn bearing produces a rough, grumbling noise as the rolling elements degrade, and if left unchecked, the cage can fracture and lock the shaft. The manufacturer machines the raceways to a surface finish that matches the original assembly, so the bearing runs quietly without requiring additional shimming or preload adjustment.
