FYH high-speed housing unit (special symbol K3) 5 Blower unit (special symbol K5) Figure 2.3 Structure of blower unit Bearings for high-speed components use non-contact oil seals that are most suitable for high-speed rotation and low torque requirements. Suitable for textile machinery, printing machinery and other applications requiring high-speed rotation, low torque and low heat generation. Rolling bearings with seats used in blowers require high-speed rotation, low heat generation, low vibration, and low noise. Therefore, in order to meet the required performance, FYH has increased the machining accuracy of the bearing by one level, and has also formed a series of blower components (special symbol K5) using non-contact oil seals. It is suitable for applications such as blowers that require high-speed rotation, low heat generation, low vibration and low noise. 6 Purification series components are aimed at reducing the size and weight of equipment and machinery, and are installed on the shaft using a convenient set screw method. The inner ring is galvanized for rust prevention and combined with a special alloy bearing housing. In addition, since the surface of the dust cover is coated with rubber, it can be closely attached to the bearing housing, and has excellent dust and water resistance. FYH stainless steel housed bearing series components (special symbol S6) are required to have good water resistance and corrosion resistance. Therefore, in order to meet the required performance, FYH uses stainless steel for bearings and bearing housings, and uses USDA (United States Department of Agriculture) H1 certified food grease for the grease. FYH ceramic ball bearing assembly (special symbol Y1～Y7) ceramic ball bearing adopts silicon nitride ceramic in the rolling part, which can be used in special environments such as high temperature, corrosion, high speed rotation, low torque, low dust and vacuum. Bearings that maintain stable performance over a long period of time. The Y1 specification (high-speed rotation specification) utilizes the lightweight characteristics of ceramic beads and is suitable for high-speed rotation environments with a dN value exceeding 200,000. The Y2 specification (universal specification) is the standard type of the ceramic ball bearing series. The heat-resistant temperature is generally 250°C (up to 300°C). It can also be used in corrosive environments such as heating water vapor or chemicals and solvents. In addition, it can also adapt to low-dust environments such as clean rooms and low torque requirements, and can maintain good performance under insulation or vacuum conditions. The Y3 specification (ultra-high temperature specification) is a new type of bearing that uses a solid lubricant in the cage in a high temperature environment (above 300°C) where grease lubrication is difficult. The heat-resistant temperature is generally 450°C (up to 500°C). The Y7 specification (high corrosion resistance specification) is a model that is especially intended for use in strongly corrosive environments (in chemical solutions, water, etc.). Mainly used in low-load, low-speed rotation environments.
