ABSTRACT:
The bearing assembly includes a bearing and a member mounted in the bearing and adapted for movement relative thereto. The bearing has a window therein and a contactor is positioned to substantially fill the window. There is a housing means for defining a chamber about the bearing and contactor, the contactor housing a portion projecting through the window to a position adjacent to the member and another portion in the chamber. An oil-impregnated wicking material substantially fills the chamber and is molded into intimate engagement with the portion of the contactor in the chamber. The oil-impregnated wicking material comprises a fluent mixture of oil and oil retaining particles. The contactor is formed as a solid mass with an interconnected network of pores therein, the pores being generally smaller than the interstices between the particles which make up the wicking material so that the lubricant in the wicking material will be drawn into the pores in the contactor by capillary action and transferred to the member.
