This ball bearing supports rotating shafts within the drive system of the host machine. It is a single-row deep-groove bearing with contact seals on both sides, which retain lubricant and exclude contaminants during operation. The bearing carries radial and moderate axial loads in applications such as gearbox input shafts, pulley idlers, and fan drives. A worn bearing produces audible rumble, shaft play, or increased operating temperature as the rolling elements and raceways degrade. SKF manufactures this bearing to the same internal clearance and seal geometry as the original assembly, so it seats correctly in the housing bore without shimming. On installation, press the bearing onto the shaft using the inner ring face only and verify that the seals are not damaged during fitting.
