This bearing supports the rotating shaft within the threshing drive of a harvesting machine. It is a spherical roller bearing with a tapered bore, designed to accommodate misalignment and heavy radial loads during operation. The C3 internal clearance allows for thermal expansion under sustained load. A worn bearing produces audible rumble and shaft play, which can lead to misalignment of the drive components and eventual seizure. As a genuine Bepco part, the bearing is machined to the same internal geometry and clearance class as the original assembly, ensuring it seats correctly on the shaft without requiring additional shimming. On installation, verify the shaft and housing are clean and free of burrs, and torque the retaining nut to specification.
