Two-piece bearing cage with side face grease carrying cavities

A cage for rotational elements of a bearing, comprising:

• first and second like retainer portions each comprising concentric inner and outer ring sections, the inner and outer ring sections each having a cylindrical surface with an annular side edge, the outer ring section being separated from an inner ring section with a plurality of spokes extending radially therebetween, the plurality of spokes and respective portions of the annular side edges of the inner and outer ring sections bounded thereby defining a plurality of cavities of each retainer portion, each retainer portion inner ring section cylindrical surface having a plurality of arcuate cut-outs extending through an edge opposite the inner ring section annular side edge, each retainer portion outer ring section having a plurality of arcuate cut-outs extending through an edge opposite the outer ring section annular side edge, the arcuate cut-outs of the inner ring and outer ring cylindrical surfaces of each retainer portion being radially aligned to form a plurality of socket portions, each retainer portion socket portion communicating with a cavity, at least one of the socket portions of each retainer portion being defined by a chord portion extending generally radially between the inner ring section and outer ring section to form a radial side of the socket portion, the chord portion forming a catch, at least one of the spokes of each retainer portion having a latch projecting axially between the inner ring section and outer ring section circumferentially adjacent the at least one socket portion across from the chord portion, the latch of the first retainer portion engaging the catch of the second retainer portion and the latch of the second retainer portion engaging the catch of the first retainer portion in a manner to secure the retainer portions together to form the cage with the socket portions of each retainer portion being in register and forming a socket adapted to receive a rotational element of the bearing.

A cage for a bearing comprising:

• a first retainer portion comprising:
• a plurality of socket portions each adapted to in part receive a rotational element of the bearing, at least one of the socket portions having a latching member adjacent a first radial edge of the socket portion and a catching member adjacent a second radial edge of the socket portion, the first radial edge being across the socket portion from the second radial edge, and
• at least one antirotational interlock formed between at least two of the socket portions;
• a plurality of cavities formed on an annular side face of the retainer portion communicating with each of the socket portions;
• and
• a second retainer portion comprising:
• a plurality of socket portions each adapted to in part receive a rotational element of the bearing, at least one of the socket portions having a latching member adjacent a first radial edge of the socket portion and a catching member adjacent a second radial edge of the socket portion, the first radial edge being across the socket portion from the second radial edge;
• and
• at least one antirotational interlock formed between at least two of the socket portions;
• a plurality of cavities formed on an annular side face of the retainer communicating with each of the socket portions;
• wherein as the at least one antirotation interlock of the first retainer portion is engaged with the at least one antirotation interlock of the second retainer portion, the latching member of the at least one socket portion of the first retainer portion engages with the catching member of the at least one socket portion of the second retainer, and the latching member of the at least one socket portion of the second retainer portion engages with the catching portion of the at least one socket portion of the first retainer portion in a manner to secure the first and second retainer portions together.
