Criteria for determining bearing life roller bearings, bearing life and reliability of the link. Due to manufacturing precision, uniformity of material differences, even in the same material, the same group of the same size bearings Spherical Roller Bearings, used under the same operating conditions, their life is not the same length. In terms of the statistical life expectancy of one unit, the longest life expectancy of 4 units relative Spherical roller bearings sales agents, the shortest 0.1-0.2 units, the longest and shortest life expectancy of more than 20 to 40 times. 90% of the bearing does not produce pitting, experienced support member relative to the axis of rotation is called a bearing. Typically lower spherical roller bearings picture, is the axis of rotation. Also the shaft does not rotate and the rotation of the housing, such as automotive wheel bearings. Rolling bearings and plain bearings into deep groove ball bearings deep groove ball bearing structure is simple, easy to use, is the largest production volume, most widely used class of bearings. It is mainly used for a bear radial load, but also bear certain axial load. When the bearing radial clearance increased, with angular contact bearings, can withstand greater axial load. Spherical Roller Bearing picture _ 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.
