  • Patent number: 10082179
    Abstract: A seal for a bearing includes an annular retaining ring defining a first radially innermost portion and a first radially outer end; and a resilient ring defining a second radially innermost portion and a second radially outer end. The first radially innermost portion and the second radially innermost portion are aligned with one another and together define a securing root of the seal. The root is adapted to seat in a groove of an inner ring of the bearing. The resilient ring projects radially outward from the annular retaining ring. The resilient ring is more flexible than the annular retaining ring. The second radially outer end defines a sealing surface adapted to slidingly engage an inner bearing surface of an outer ring of the bearing. The first radially outer end of the retaining ring terminates between the first radially innermost portion and the second radially outer end of the resilient ring.

  • Patent number: 6283635
    Abstract: A bearing housing includes a mounting for securing a bearing housing to a support surface and a bore adapted for receiving a bearing. An intermediate ring having a mechanical interlock and configured to mount over the bearing housing is positioned adjacent the bearing housing bore. An adhesive connection between the bearing housing and the intermediate ring connects the intermediate ring to the bearing housing. A bearing cover is positioned over the housing bore and engages the intermediate ring such that the mechanical interlock retains the bearing cover.
