wind power bearing fall rolling sound

The noise in general, mostly large bearings at low speeds and bear radial load. When the operation of the bearing in the radial load, load and non load bearing, wind power bearing‍ if the bearing has a radial clearance, the non load area of the rolling body and the inner raceway no contact, but because of the action of centrifugal force may be associated with the outer ring contact, therefore, at low speeds, the centrifugal force is less than when rolling body weight when the natural vibration and noise, the rolling of the fall and and inner raceway or cage collision and motivate the bearing, Flange Slewing Bearing‍ and has the following characteristics:

Easy to produce A. grease lubrication, oil lubrication is not easy to produce. When use inferior lubricating grease are more susceptible to.                                                                                                                                                                               ‍
