Abstract
A rolling bearing assembly for mounting a shaft or similar member which has a housing encircling the shaft with at least one rolling bearing installed between two securing rings. The assembly consists of an outer and an inner race and at least one row of rolling elements. It has annular chambers in the housing on either side of the bearing, closed off on their outer edges by annular seals which are attached to the housing and in contact with the bearing shaft. It has at least one hole opening into one of the annular chambers throught the wall of the housing, capable of being placed in communication on the outside with a feeding device for introducing a lubricant into the housing. There are two channels (17, 17') extending through the wall of the housing (1) and located diametrally opposed to each other, each opening into the closed annular chamber (8), and in that a trough-like receptacle (18) is accommodated in said channels, in which an excess of lubricant can be collected.
