Noise generally lower spherical roller bearings pictures, 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 at a certain radial bearing clearance Spherical roller bearings sales agents, non-load zone of rolling elements and the inner raceway no contact, but it may be due to the centrifugal force into contact with the outer ring, for which 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 and excitation cage bearing NTN Bearing natural vibration and noise should not be placed directly on the bottom, to prevent contact with the bottom bearing parts of the local heating is too high, or the bottom sediment of dirt into the bearing. Points to note are as follows sump heating, use non-corrosive good thermal stability of mineral oil roller bearings, preferably transformer oil, oil and containers should be kept clean. Sump capacity should be heated NTN Bearing size and oil may be, if the container is too small, in continuous operation, an oil temperature will quickly drop into the bearing, the effect on the poor. Shenzhen Spherical roller bearings supplier, Long Yu (certified), roller bearings provided by the Dongguan City, Long-Bearing Machinery Co., Ltd. Dongguan City, Long-Bearing Machinery Co., Ltd. (long-yu.net) Dongguan, Guangdong, thrust roller bearings leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
