Drain proof bearing assembly

A drain proof bearing assembly comprising:

• a seat having an axially arranged hollow space;
• and an upper end thereof being opened;
• a cylindrical bearing being receivable in a hollow space of the seat;
• the bearing being formed with an axial hole axially penetrating therethrough for receiving a spindle;
• an upper side of the bearing near an upper opening of the axial hole of the bearing being formed with an annual recess for receiving a drain proof ring;
• a plurality of radial notches being formed radially on an upper surface of the bearing;
• an outer surface of the bearing being formed with a plurality of oil guiding trenches;
• an upper end of each oil guiding trench being communicated with one end of a respective notch and another end of the notch being communicated to the annular recess;
• thus, by the notches, the oil guiding trenches being communicated to the annular recess;
• and
• a press plate having an inner hollow penetrating hole and receivable in the hollow space of the seat;
• wherein in installation, the bearing is received into the hollow space of the seat;
• then, the spindle is received into the axial hole of the bearing while the annual groove of the seat is at an upper side of the bearing;
• then the drain proof ring is fitted into the annular recess of the bearing so as to clamp the spindle tightly in the axial hole of the bearing;
• and finally the press plate is located at an upper side of the bearing and is received within the hollow space of the seat.
