<p>AN EXEMPLARY BEARING CARTRIDGE ASSEMBLY (44) INCLUDES AN INNER SLEEVE (52). AN OUTER HOUSING (50) IS SUPPORTED FOR ROTATION RELATIVE TO THE INNER SLEEVE (52). A BEARING MEMBER (54) WITHIN THE OUTER HOUSING (50) AND RECEIVED ABOUT THE INNER SLEEVE (52) FACILITATES ROTATION OF THE OUTER HOUSING (50) RELATIVE TO THE INNER SLEEVE (52). THE BEARING MEMBER (54) HAS AN AXIAL DIMENSION (E.G., A WIDTH) THAT IS SMALLER THAN AN AXIAL INNER DIMENSION OF THE OUTER HOUSING (50). THE BEARING MEMBER (54) IS POSITIONED RELATIVE TO THE INNER SLEEVE (52) AND THE OUTER HOUSING (50) TO PROVIDE A FIRST LUBRICANT SPACE (70) BETWEEN ONE SIDE WALL OF THE OUTER HOUSING (50) AND THE BEARING MEMBER (54) AND A SECOND LUBRICANT (72) SPACE BETWEEN AN OPPOSITE SIDE WALL OF THE OUTER HOUSING (50) AND THE BEARING MEMBER. THERE IS AT LEAST ONE THROUGH PASSAGE BETWEEN THE FIRST AND SECOND LUBRICANT SPACES (70, 72) TO ALLOW LUBRICANT TO MOVE BETWEEN THEM. (FIG. 1)</p> |
