BEARING WEAR INDICATOR

摘要

A bearing assembly (10) for supporting and guiding a moving member includes a first bearing member (16) and a second bearing member (14). The second bearing member (14) and the first bearing member (16) have movement relative to one another. The second bearing member (14) includes a wearing surface (26) in contact with the first bearing member (16). The wearing surface (26) wears in response to the relative movement between the first and second bearing members (16, 14). The second bearing member (14) also includes a chamber (34) and a wear identifier (35). The chamber is located behind the wearing surface (26). The wear identifier (35) is within the chamber (34). Upon sufficient wear of the wearing surface (26) the wear identifier (35) is released from the chamber (34) onto the wearing surface (26).
