Center flange bearing suitable for use with electrical machinery

A bearing assembly for supporting a rotatable shaft, said bearing assembly comprising:

• a bearing housing having a base element and a cap element matable to facilitate mounting of said bearing housing about said shaft, said base element defining a sump for containing a lubricant fluid therein and further defining a first partial shaft receiving portion, said cap element defining a second partial shaft receiving portion complementary to said first partial shaft receiving portion to produce a complete shaft receiving portion when said base element and said cap element are mated;
• a bearing liner contained within said complete shaft receiving portion of said bearing housing, said bearing liner defining a shaft bore through which said rotatable shaft operatively extends;
• and
• said complete shaft receiving portion having a first axial length approximately equal to a second axial length of said bearing liner.

• first and second lubricant seals located at respective opposite axial ends of said complete shaft receiving portion of said bearing housing, each of said first and second lubricant seals having an attachment portion and a seal portion, said attachment portion being connected to said complete shaft receiving portion of said bearing housing and defining at least one lubricant fluid return path in a bottom portion thereof, said seal portion extending about said rotatable shaft;
• and
• said respective end faces of said complete shaft receiving portion each defining therein at least one lubricant fluid return bore providing fluid communication between said sump and said lubricant fluid return path defined in an associated of said lubricant seals.

A bearing assembly for supporting a rotatable shaft, said bearing assembly comprising:

• a bearing housing having a shaft receiving portion;
• a bearing mechanism located within shaft receiving portion of said bearing housing, said bearing mechanism defining a shaft bore through which said rotatable shaft operatively extends;
• first and second lubricant seals located at respective opposite axial ends of said shaft receiving portion, each of said lubricant seals including an annular flange portion integrally extending into an extension portion having an annular seal structure located on an inside thereof, said annular flange portion being connected to a respective end face of said shaft receiving portion and said extension portion being situated about said shaft;
• and
• said extension portion of at least one of said first and second lubricant seals defining therein at least one radial receiving hole for mounting a selected sensor device.
