General noise reduction roller bearings wholesale, mostly occurs at low speeds and radial load of large bearings. When NTN bearings operating under radial load, load bearing and non-load zone area, if the bearing has a radial clearance, rolling non-load bearing area is not in contact with the inner race, but the effect of centrifugal force may be associated with outer contacts, for spherical roller bearings sales agents, at low speeds, when the centrifugal force is less than the weight of the rolling elements, the rolling elements and the inner race fall or collision cage and stimulate the natural vibration and noise by employing NTN Bearing preload method can effectively reduce the noise roller bearings, NTN bearings work to reduce the installed capacity after the radial clearance, the choice of a good lubricant can also be improved, some foreign companies use light rolling elements Spherical roller bearings price, such as a ceramic roll child or hollow roller and other technical measures to prevent such noise. So that the roller between the track and the rolling elements generate small fluctuations in the natural vibration excitation vibration system. Although it is inevitable, but can take high-precision machining parts work surface, the correct selection and precise NTN Bearing NTN Bearing make use of noise damping.
