A bearing support assembly (10) comprising a bearing (12) supported within a bearing block (14) is provided. A shaft (26) is arranged to rotate within the bearing (12) and a disc member (34) is carried on the shaft (26) proximate to the bearing block (14). A ring member (20) is secured to the bearing block (14) so that in the event of bearing failure the disc member (34) engages with the ring member (20) so as to support the shaft (26) in rotational motion. The disc member has a diameter that is larger than the outer diameter of the ring member. The ring member (20) is at least partially recessed into the thickness of the disc member (34). The assembly may be utilized in agricultural machinery which include rotors (30) which are supported on rotating shafts. The ring member (20) may provide a labyrinth seal which inhibits the ingress of particulate matter into the bearing.
