Abstract

A radial shaft sealing ring for the sealing separation of an internal space (6), from an external space (5), with a sealing lip (2) delimited by a first and a second annular surface (3, 4) of a cone frustum, wherein, the first annular surface (3) is oriented towards the external space (5), and the second annular surface (4) is oriented towards the internal space (6), wherein the annular surfaces (3, 4) are connected to each other via a ring-shaped contact surface (23) of the sealing lip (2), which rests on the shaft (7), wherein the first annular surface (3) forms with the shaft (7) a first angle ([beta]') of 23-40 DEG in the installed position, wherein an inner diameter (24) of the ring-shaped contact surface (23) is 1-15 mm in the installed position.

Description

technical field [0001] The invention relates to the sealing of a housing opening passed through by a shaft by means of a sealing ring, wherein the sealing ring separates an inner space, which at least partially surrounds the shaft, from an outer space. In this case, the interior can be a housing interior, which is separated by a sealing ring in a pressure-tight manner from the outer space surrounding the housing, so that liquids, gases and / or particulate matter cannot escape from the housing. The material cannot flow out of the cavity, and the material cannot enter the inner cavity of the housing from the outer cavity. The invention therefore also relates to a housing with such a sealing ring. Background technique [0002] A sealing ring designed as a radial shaft sealing ring is known from EP 1156242 B1, which is formed from an annular, metallic support body and a sealing lip connected thereto. In the installed position, the radial shaft sealing ring is passed through by ...
