Guangzhou jiangmen bearing factory meticulous planning bearing parameters

Guangzhou jiangmen bearing factory meticulous planning bearing parameters under certain load, bearing before pitting experiences of revolution or hours called bearing life. The using life of rolling bearings by revolution ( Or under a certain speed of working time) Definition: within the using life of the bearing should be on any bearing ring or rolling body produce initial fatigue damage ( Stripping or defect) 。 However, no matter in lab tests or in practice, can clear to see that under the condition of the same work, same bearing appearance and practice of life are quite different. In addition, the bearing's life there are several different definitions of one of them is the so-called 'working life. This means that the bearing before the damage can reach the practice of life was caused by wear and damage provoked, usually not because of tired, but by the wear and tear, corrosion, seal damage and other reasons make up. In order to sure the specification of the bearing life, the life of the bearing is associated with strong sex. Due to the average sex difference data of manufacturing precision and under the same working conditions using the same material and size of the same bearing the use of life is different also. If statistical life is 1 unit, the relative life is 4 units, short life is 0. 1 - 0. 2 units, short-lived and the ratio of the short life is 20 40 times. 90% of the high temperature bearing no pitting, the experience of revolution or hours called bearing rated life. Rated dynamic load bearing capacity and to compare the influence of pitting, rules when the bearing rated life expectancy of one million RPM ( 106). , it is able to accept the load as the basic dynamic load rating, expressed as a C. That is to say, under the action of dynamic load rating C, bearing in turn millions ( 106). No pitting corrosion failure of sex (90%), C, the greater the load to the higher. The basic dynamic load rating 1. The centripetal bearing means pure radial load 2. Thrust ball bearing is refers to the pure axial load 3. Of pure radial displacement of radial thrust bearing is refers to the radial weight on an article: guangzhou, foshan bearing manufacturers use bearing steel under the ideas of an article: guangzhou zhongshan insight into the bearing industry development present situation
