The SealMaster SF-21 1-5/16" Flange-Mount Ball Bearing is a rotating component used in the blower and fan assembly of air handlers and packaged units to ensure that rotating shafts move smoothly with a low friction value. It is mounted in a flange housing and aligned with the driven shaft and has precision rolling elements that helps to support radial and axial loads during usage. The mounting surface is attached to the shaft and set screws as specified, which assists in keeping the rotation stable, moving components, and ensuring the overall performance of the entire system.
