Abstract
A bearing assembly for a door linkage. The bearing assembly is placed about a shaft which runs through a central opening in an arm, and the arm rotates about the shaft. The bearing assembly comprises a central composition bushing, a boss which is rotationally locked with the arm, and a plate. The central opening is large enough such that all the elements of the bearing assembly can be removed without disassembling the arm. The plate retains the elements of the bearing assembly in place when the arm is in use. The plate may also provide torque transmission between the boss and the arm.
