A device for lubricating bearings and the like including a housing for containing a lubricant, and a movable piston adapted to be inserted into the housing in contact with said lubricant. The piston includes an upper concave surface, for communication of the lubricant with a bearing to be lubricated, and a passage for flow of lubricant. Compression of the piston against the lubricant causes flow of lubricant from below the piston to above the piston. An adapter, or volume-filling means, is disposed on the upper piston surface for filing a portion of a volume defined between the upper, concave piston surface and the wheel bearing. The volume-filling means includes lubricant flow passages for allowing lubricant to flow from said upper concave piston surface to the wheel bearing.
