Size Range: Applications: Manufacturing Capability: Nine types of gearbox bearing with OD 30- 2500mm. Industrial Gearbox, Wind Turbine Gearbox and Vehicle Gearbox, etc. ZWZ can provide no less than 2000 specifications, 1 million gearbox bearings every month. Manufacturing cycle: 35 days by through hardened steel, and 50 days by case hardened steel. φ φ 1 Selection of Bearing 1.1 The use conditions and the surrounding conditions of the bearings The variety in kinds and types and dimensions of power train bearings makes the selection of the most appropriate bearings very important in order to achieve the expected functions of the mechanical devices. Analyses and evaluations from different viewpoints on the factors to be considered must be made in order to choose the bearings. There are no special regulations on such selection procedures, but the steps below are followed: Understand the work conditions of the mechanical device and the bearings. Define the requirements on the bearing to be chosen. Choose the type of the bearing. Choose the configuration way of the bearing Choose the dimensions of the bearing. Choose the specifications of the bearing Choose the mounting method for the bearing Correct definitions on the application position in the mechanical device and the use conditions and surrounding conditions are the pre-conditions of choosing the proper bearing. For this purpose, the following figures and data are required: The functions and structure of the mechanical device. The application position Loads (how big and in which directions); Rotate speed. Vibration and shock. Temperature of the bearing (surrounding temperature and rises). Surrounding ambience (corrosion, cleanness, lubrication).
