Details
Self-aligning ball bearings are designed to accommodate misalignment between the shaft and the housing without causing undue stress on the bearing or reducing its operational efficiency. They consist of an inner and outer ring with double-row steel balls and a cage that separates and guides the balls. It can handle both radial and axial loads, making it suitable for a wide range of applications.
