Bearing Nuers and Types Explained - Engineer Student

Self-Aligning Ball Bearing. This kind of ball bearing has a spherical outer race, allowing the axis of the bearing to "wander around". This is important because misalignment is one of the big causes of bearing failure. 2: Barrel and Spherical Roller Bearings. 3: Tapered Roller Bearing. Designed to take large axial loads as well as radial loads. 4
