Ways to reduce bearing noise

Ways to reduce bearing noise (1) Method of using chemical additives Adding certain chemical additives to the bearing lubricant can reduce bearing noise. For example, a low-noise grease containing noise-reducing additives produced by a factory in Tianjin can reduce bearing noise by 3.9-9.2dB from the original basis. , Suitable for use in miniature or small bearings.
