  • Bearing Numbers and Types Explained - Engineer

    2021-1-31 · 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: Deep Groove Double-Row Ball Bearing

  • How to Identify Bearings by Bearing Number -

    2015-1-16 · Thus, we can easily identify now that in case of bearing 6305ZZ, the first digit ‘ 6 ‘ means the bearing type is ‘Single row deep groove ball bearing’. In case of Inch bearings, the bearing’s first digit will be ‘R’. After ‘R’, the size of the bearing will be given in 1/16 th of an inch. To understand it better, Lets take an example of Inch bearing.
