A contamination-resistant bearing assembly includes an outer ring mounted within a housing and an inner ring rotatably supported from the outer ring. Inboard and outboard seal structures are disposed within a bearing space defined between the rings and prevent contaminants from entering a rolling element lubrication zone. A surface seal may also be included to protect the spherical interface between the housing and outer ring. The improved structure allows dynamic alignment of the bearing assembly when acted on by outside forces and also allows for extended operation under maintenance free conditions with no need for relubrication.

Self-aligning maintenance free bearing unit for agricultural applications

A bearing assembly for a shaft including an inner ring that mounts on the shaft and an outer ring disposed concentrically about the inner ring. Ball bearings are interposed between the inner and outer rings. Fingers are formed on one side of the inner ring and they extend axially with adjacent fingers defining longitudinally extending slots. An outwardly opening notch is formed in each of the fingers to create an outwardly opening circumferential groove around the inner ring. A compressible annular locking collar is positioned circumferentially around the fingers. A fastener screw is operable to compress the fingers into locking engagement with the shaft. A first elongated locking rod extends through the locking collar and into an outwardly opening notch in one of the fingers to secure the locking collar against axial movement relative to the fingers. A second locking rod extends through the locking collar to fit into a slot between a pair of fingers to secure the locking collar against circumferential movement relative to the fingers.

Bearing locking collar retainer

A bearing assembly comprising an inner ring for mounting on a shaft, an outer ring disposed concentrically about the inner ring, a plurality of roller elements interposed between the inner and outer rings. The inner ring includes fingers which extend axially from a side thereof and terminate in outer annular end walls. A compressible annular locking collar is positioned circumferentially about the fingers. The locking collar has a larger inside diameter and a smaller inside diameter. The larger inside diameter has an axial length not greater than the axial length of the fingers. The larger inside diameter is sized to fit over and engage the fingers. The smaller inside diameter is sized to define an annular radially extending wall which engages the outer annular end walls of the fingers. The locking collar has a fastener screw for causing the larger diameter of the locking collar to compress the fingers into locking engagement with the shaft.
