Abstract: A device for supplying a lubricant comprises a receptacle to contain the lubricant with an opening arranged in the bottom thereof. A piston member is sealingly displaceable along the walls inside the receptacle and located in initial position near the top of the receptacle. At least one extendable or expandable member is supported by the receptacle at the circumference over the lubricant present in the receptacle with a bottom portion located near and above the piston member which member contains an electrolyte. At least one galvanic element is supported over the electrolyte inside the receptacle, and a flexible member and rupturable support are provided for bringing the galvanic element into contact with the electrolyte. The said extendable or expandable member with the electrolyte present therein and the galvanic element form a separate assembly detachable from the receptacle.

Abstract: Seal assembly for a rolling bearing assembly having an inner race ring (5) adapted to be mounted on a shaft member (18) and an outer race ring (4) radially spaced from the inner race ring (5) defining an annular space for rolling elements (16) comprising a contoured sealing ring (1) connected to the outer race ring (4) cooperatively associated with a closure member (2) mounted on the shaft member adjacent one axial end of said inner race ring (5) to seal the annular space at least at one axial end of the rolling bearing assembly, said sealing ring (1) having an outer portion (3) connected to the outer race ring (4) inner and outer axially directed annular wall portions (7, 10) connected by an intermediate wall portion (8) and spaced apart radially to define an enlarged chamber overlying and spaced radially outwardly of said closure member (2) annular lubricant chamber (13), said closure member comprising an annular body portion (2a) and an axially outwardly directed flange portion (14) spaced radially from th
