Do you understand all the bearing knowledge?

Bearings are generally composed of an inner ring, an outer ring, a rolling element, and a cage. For sealed bearings, add lubricant and a sealing ring (or dust cap). That's what bearings are all about. According to the working condition of the bearing, different types of approaches can be selected to better play the function of the bearing and extend the service life of the bearing. We choose bearings to consider the following factors: 1. Radial load 2. Axial load 3. Speed requirements 4. Radial runout 5. Axial runout 6. Operating temperature 7. Noise requirements 8. Lubrication status Bearing models are generally composed of pre-designation, primary designation, and post-designation. Under normal circumstances, the bearing type is only indicated by the primary type. The basic model generally contains three parts, type code, size code, and inside diameter code. The postcode is used to indicate the bearing structure, tolerance, and special requirements of materials with letters and numbers. The prefix code indicates the partial parts of the bearing, which are represented by letters. General bearing (rolling bearing) code method, divided into pre-code, basic code, and postcode.
