Silent bearing is a kind of bearing which can reduce the noise of mechanical equipment. The traditional bearing will produce noise because of the friction and running of the internal parts, but the quiet bearing adopts a series of new materials and designs to reduce the noise by reducing the internal friction and optimizing the structure, etc. , so that the operation of the equipment more stable, better mute effect. This bearing is often used in music equipment, audio-visual equipment, computer maintenance and other fields. The advantages of quiet bearing: 1, low noise: due to the use of new materials and optimized structure, quiet bearing at high speed operation can reduce the noise caused by mechanical interference. Longer Life: silent bearings are generally better lubricated and therefore have a longer life than conventional bearings. Low friction: because they have less friction, they can consume less power, improve efficiency, and reduce wear and tear caused by excessive friction. Energy-saving: mechanical devices with mute bearings typically consume less electricity, which is good for the environment and energy savings. Disadvantages of silent bearings: high cost: due to its design and material properties, silent bearings are usually more expensive than traditional bearings. Reliability: some types of silent bearings may appear more frequent problems, such as high temperature, sound instability, vibration and other problems. In general, silent bearings can improve the efficiency of mechanical equipment, reduce noise pollution, energy saving and environmental protection, but they are not a foolproof solution. In the selection and use of mute bearings, different pros and cons need to be carefully considered to ensure that the desired benefits can be obtained.
