Abstract
A rotatable member (3) has on its outside surface a contoured surface portion (15) which widens conically upwards in diameter, is contiguous with a lubricant storage chamber (14) and extends axially to near a bearing (11) by which the rotatable member (3) is rotatably mounted in a housing (4). Lubricant discharging downwardly by gravity from the bearing (11) returns upwardly along the surface part (15) and reaches a zone which is below the bearing (11) and from which the same takes up lubricant. The bearing (11) is therefore supplied with lubricant during the rotation of the rotatable member (3) so that uniform lubrication in a thin layer is ensured. The mounting is used more particularly in a cap of a cap spinning machine or cap twisting machine.
