Abstract
Disclosed is a pulley assembly including a pulley having an axis of rotation a pulley shell, and a bearing; a shaft having a pulley-receiving end that receives the pulley; and a first bearing shield disposed at the pulley-receiving end of the shaft. The pulley shell includes an annular wall that defines an opening for housing the bearing. The bearing is housed therein and has an inner race, outer race, and a rolling element. The first bearing shield includes a deflected sealing member biases against at least one of the outer race of the bearing and the pulley shell as a first contact seal to protect the bearing from contaminants.
