This bearing supports the feeder-house drum shaft that transfers crop material from the header into the threshing mechanism. It is a sealed, greased-for-life ball bearing designed for the high radial and moderate axial loads present at the drum pivot points. The double-lip contact seal on both sides prevents ingress of dust, chaff, and moisture, which are the primary causes of raceway pitting and premature failure. A worn bearing produces a growling noise during operation and allows shaft deflection that misaligns the feeder chain. As an INA original, the internal clearance and seal geometry match the housing bore and shaft diameter of the original assembly, so no shimming or adapter sleeves are required for installation.
