Flange bearings are used when the shaft is perpendicular to the mount surface. Flange bearings are a complete assembly consisting of a housing, means of lubrication, and rolling elements. Units often include a locking collar or setscrew to attach to the shaft. Flange bearings can utilize ball, roller, or plain components. Between two and four bolts are located within the flange to facilitate mounting. Flange bearings are often used in industries such as food, paper, automotive, and chemical.
