ABSTRACT:
An improved wear-indicating pivot joint includes a bearing assembly which supports a stud for both axial and rotational movement. The bearing assembly prevents sidewise tilting movement of the stud during axial and rotational movement of the stud about its own central axis. A wear take-up arrangement is provided to compensate for normal wear between a bearing surface and the stud. The wear take-up arrangement includes a spring which applies a force to a bearing member to continuously urge the bearing surface into engagement with the stud to hold the stud against sidewise tilting movement. However, upon the occurrence of excessive wear between the bearing surface and the stud, the bearing surface is ineffective to hold the stud against sidewise tilting movement to thereby signal the occurrence of excessive wear.
