发明名称 RADIAL NEEDLE BEARING UNIT
摘要 A radial needle bearing unit for supporting a shaft, which has an outer sleeve with at least one radially inwardly directed rim and a cage guiding hearing needles. For sealing purposes, a sealing element is disposed in an annular space delimited by the rim and the cage. The sealing element is an outwardly expanding sealing ring made of a polymer material resting radially outwardly against the inner lateral surface of the outer sleeve and radially inwardly against the lateral surface of the shaft so that a radial/radial seal is formed. The outer sleeve has, at least in one peripheral location, a holding lug which is formed by stamping or cutting and protrudes the lateral surface of the outer sleeve in a spring-loaded manner.
