Bearing Number Codes [Part 1]

In this video, we will cover the bearing number code system for metric-series bearing. We will focus on the International Organization for Standardization (ISO) and the Japanese Industrial Standards (JIS). Through examples, we will explore the composition and arrangement of bearing numbers, covering the three main sections in detail. For instance, we will outline the code series numbers assigned to each bearing type — Code 1 for self-aligning bearings, Code 2 for spherical roller bearings, Code 3 for both tapered roller bearings and double-row angular contact bearings, Code 4 for double-row ball bearings, Code 5 for single-direction thrust ball bearings, and Code 6 for single-row deep groove ball bearings, among others. The sections that will be covered in this video are as follows: 1. Supplementary Prefix Code 2. Basic Numbers: a. Bearing Series Code b. Dimensions Series Code c. Bore Diameter Code d. Contact Angle Code 3. Supplementary Suffix Code: a. Internal modifications code b. Cage code c. Seal/Shield type code d. Raceway external configuration code e. Dublex arrangement code f. Internal clearance preload code g. Tolerance code h. Lubrication code You can find more videos on our channel: ‪@CAEPlus‬
