This bearing-with-housing assembly supports the deflector shaft on the threshing unit of a grain harvester. It carries the radial load from the rotating deflector and maintains alignment with the downstream auger or beater that receives the crop flow. A worn bearing allows shaft play, which can cause the deflector to contact the housing or throw the belt out of alignment. The housing bolts to the machine frame through its mounting holes; on reinstall, confirm the bolts are torqued to spec and the shaft rotates freely before locking the fasteners.
