The bearing assembly has a fixed lower housing with a stepped cavity containing bearings, and an upper housing rotatably carried in the bearings that has a through bore affording a lubricant chamber. The lower and upper housings have confronting external flanges between which is a metal-to- metal lubricant seal having elastomeric ring that must be compressed to make the seal effective. The bearing assembly in- cludes surface engaging preload means in the through bore to depress the upper housing and thus compress the elastomeric rings, after which a cover plate is fastened on the top of the upper housing member and the lower end of the auger shaft is seated on a mating square stub on the cover plate. The weight of the auger further depresses the upper housing to disengage the surfaces of the preload means.
