Bearing wear indicator

摘要

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